     SUMMARY INFORMATION AND RISK FACTORS.

     On June 12, 1989 Interspec, Inc. ("Interspec") issued
certain convertible subordinated notes (the "Notes") by private 
placement to five Noteholders for the total principal amount 
of $10 million.  Under the terms of the Notes, the unpaid principal 
amount could be converted at the option of the Noteholders or
Interspec, under certain defined conditions, into common stock
of Interspec at a defined conversion price.  Repayments of
principal were made by Interspec through May, 1994, at which
time the unpaid principal amount was $6.5 million.

     On May 17, 1994 ATL acquired Interspec through a stock
for stock acquisition which was approved by the shareholders
of both companies.  The Company registered 2,588,000 shares of
Common Stock in April, 1994 to effect the merger. An election
to convert by either party at the time of the merger would
have resulted in the issuance of 383,480 shares of Common Stock 
to the Noteholders based upon the then outstanding principal 
amount of the Notes, $6.5 million, and the conversion ratio 
applicable to all Interspec shareholders.

     On November 30, 1995 the conditions under which the
Company had the right to convert the remaining principal
amounts of the Notes into Common Stock were satisfied, and the
Company gave the four remaining Noteholders notice of its
intent to effect such a conversion on February 1, 1996.  The
repayments of principal since the time of the merger had, by
November 30, 1995, reduced the principal amount of the Notes
to $3,375,000, and have thereby reduced the number of shares
required for the conversion.  The Shares registered hereby 
comprises Common Stock which which has been received by the 
Noteholders in lieu of cash payments of principal under the Notes.  
Details on all holdings of Common Stock by the Noteholders 
which are known to the Company are given in the table below.  
See "The Notes and the Noteholders."

     A prospective purchaser of the Shares should take into
account the following:

     Lack of Diversification.  The Company is engaged
primarily in the diagnostic medical ultrasound business.
Consequently, the Company is subject to adverse developments
in the healthcare industry generally, and in particular in the
medical ultrasound business as a result of competition,
technological change, governmental regulation, change in third
party reimbursement policies, third party intellectual
property claims, seasonal fluctuations in medical equipment
purchasing, or other factors to a greater extent than a
company with a more diverse business.

     Volatility of Stock Price; Absence of Dividends. The
market price for securities of medical technology companies
has historically been volatile.  Among other things, 
announcements of technical innovations or new commercial products 
by ATL or its competitors, development concerning proprietary 
rights, including patents and litigation matters, publicity 
regarding actual or potential medical results with products under 
development by ATL or its competitors, and regulatory developments 
in both the United States and foreign countries, as well as period-
to-period fluctuations in revenues and financial results, can have 
a significant impact on the market price of ATL Common Stock.  The 
Company does not pay cash dividends on shares of Common Stock.

     Intense Competition.  The markets for diagnostic medical
ultrasound products are intensely competitive.  ATL faces
competition from many domestic and foreign companies.  Several
of the Company's competitors have far greater financial,
marketing, servicing, technical and research and development
resources than those of ATL.  Several of these competitors
have recently intensified their efforts in the market for

Page 3



diagnostic ultrasound and have introduced new lines of
products which compete with those of ATL.  Several of these
competitors have the ability to combine their resources in
ultrasound with those of other medical imaging modalities,
including the servicing of these product lines.  There can be
no assurance that actual or potential competitors will not
develop and market products which compete effectively with
those of ATL.  Competition could adversely affect the
Company's revenues and profitability.

     Recent Losses.  For the fiscal year ending December 31, 1994 
the Company reported a loss of $20.2 million, including non-
recurring charges of $12.0 million comprising $7.0 million for 
the acquisition of Interspec and restructuring expenses associated 
with corporate streamlining activities and a provision of $5.0 
million for a patent litigation claim.  For the first nine months 
of 1995 the Company reported a net loss of $0.2 million, including 
restructuring and relocation expenses of $4.7 million associated 
with the consolidation of the Company's Interspec operations in 
Ambler, Pennsylvania.  The Company has reported that it expects to 
incur relocation and restructuring expenses in 1995 of 
approximately $6.0 million associated with this consolidation.  
There can be no assurance that losses will not be sustained in the 
future or that profitability will be achieved by the Company on a 
short or long term basis.

     Rapid Technological Change.  The diagnostic medical ultrasound 
business is characterized by rapidly evolving technology and 
continuing competitive pressure to develop and market new products 
and product features.  The complexity of the Company's products could 
result in delays in product delivery as improvements and new features 
are made to the hardware and software of the products.  There can be 
no assurance that the product changes and modifications in the 
factory and in the field will not result in disruption of product 
sales and shipments, or additional expense, in any particular period.  
There can be an assurance that the Company will be able to develop 
and market new competitive products on a cost-effective and timely 
basis, that such products will compete favorably with products 
developed by others, or that the Company's existing technology will 
not superseded by new technology developed by competitors. 

     Government Regulation.  ATL's manufacturing facilities, products, 
and product labeling are subject to extensive and rigorous governmental 
regulation by the U.S. Food and Drug Administration (FDA) and 
corresponding state and foreign agencies.  In conjunction with the 
processing of the Company's PMA application (see "Recent Developments"), 
the FDA is currently auditing the Company's products and processes for 
compliance with FDA rules and regulations.  There can be no assurance 
that the Company will be able to timely obtain necessary regulatory 
approvals in the future, and delays in the receipt of or failure to 
receive such approvals, the loss of existing approvals, failure to 
comply with regulatory requirements, and the cost of bringing products 
and processes into compliance with regulatory requirements could have 
a material adverse effect on the business, financial condition
and results of operations of the Company.

     Uncertain Healthcare Environment.  Uncertainty of healthcare 
legislation and economic conditions in recent years have caused 
healthcare providers who purchase capital medical equipment including 
ultrasound equipment to exercise caution in making capital purchases.  
This has led to a deferral in the purchase of ultrasound and other 
capital equipment.  These conditions and others have led to the 
consolidation of many healthcare providers and a consequent reduction 
in the medical capital equipment markets in some countries.  The 
continuing effects of such uncertainty both domestically and in 
international markets may continue to adversely affect the Company's 
unit volumes, product pricing, and profit margins.

     Dependence on Third-Party Reimbursement.  ATL's products are used 
by healthcare providers for medical services for which the provider 
may seek reimbursement of purchase and/or use costs from various 
third-party payors such as government programs and private health 
insurance plans.  Such reimbursement is subject to the regulations 
and policies of governmental agencies and third-party payors.  The 
Company cannot predict what changes may occur in these regulations 
and policies, nor the effect of such changes on the business of the 
Company.

     Uncertainty of Patents and Proprietary Rights.  Companies in 
technology businesses routinely review the products of others for 
possible conflict with their own patent rights.  ATL from time to time 
receives notices of claims from others alleging patent infringement.  
ATL is currently awaiting a decision on damages payable by the Company 
in an infringement action on an expired patent in which the plaintiff 
is seeking over $5 million in 

Page 4


damages, and a threefold enhancement of damages.  There can be 
no assurance that the Company will not be subject to other claims 
of patent infringement or that a claim will not require that the 
Company pay substantial damages or delete certain features from 
its products or both. Such claims could temporarily interrupt the 
Company's ability to ship affected products.

     Dependence on Suppliers For Critical Components.  ATL
depends on some single-source vendors for certain important
component parts for certain products.  Such vendors can
occasionally experience problems with their ability to deliver
components needed by the Company, and certain components have
long lead-times for delivery.  An abrupt disruption in the
supply of these components could have a material adverse
effect on the Company's production of affected products.


     RECENT DEVELOPMENTS.

     On December 11, 1995 a U.S. Food and Drug Administration
(FDA) Advisory Committee Panel voted unanimously to recommend
FDA approval, with certain modifications, of the pre-market
approval (PMA) application of ATL which would allow a new
clinical application of ultrasound that, in conjunction with
mammography, would provide a high level of confidence in
differentiating benign from malignant or suspicious breast
lesions, and thereby reduce the need for breast biopsy.  The
FDA usually follows the recommendation of its Advisory
Committee Panel but is not obliged to do so.  On January 25, 
1995 the FDA determined the PMA to be approvable pending the
satisfaction by ATL of certain conditions and requirements.
The Company is in the process or responding to the FDA.  
A final determination on approval of the PMA is expected later 
in 1996.

     USE OF PROCEEDS.

     The Shares offered are being registered for the accounts
of the Noteholders and, accordingly, the Company will not
receive any proceeds from the sale of the Shares.


     THE NOTES AND THE NOTEHOLDERS.

     The Notes were issued to the Noteholders on June 12, 1989
by Interspec, Inc., and interest of 11% per annum on the
outstanding principal amount of the Notes has been paid
semiannually since their issue date.  The initial principal
amount of the Notes was $10 million.  Of this initial amount,
$3.5 million was repaid prior to the merger of Interspec and
the Company in May, 1994, and $2,632,353 has been repaid in
accordance with the terms of the Notes since May, 1994.  The
principal amount of the Notes which has been repaid in the
form of the Shares which are the subject of this registration 
statement is $3,617,605.

     On May 17, 1994 the Company acquired Interspec in a stock
for stock acquisition approved by the shareholders of both
companies.  As a consequence thereof, the Company guaranteed
the repayment of the Notes and the Notes were amended to
become convertible into Common Stock at the option of the
Company at a conversion price of $16.95 per share (subject to
certain adjustments which have not occurred) in the event the
market price of the Common Stock exceeded the conversion price
by at least 20% for fifteen consecutive trading days.  These
criteria were satisfied on November 30, 1995 and notice of the
Company's election to convert the Notes was given to all
Noteholders on November 30, 1995. The Company intends to
complete the conversion by the issuance to the Noteholders of
all Shares by February 1, 1996.

     The Shares are being registered pursuant to the terms of
a Registration Agreement of July 14, 1988 between Interspec
and various Interspec securityholders, as amended June 12,
1989, which provides the Noteholders with certain "demand"
registration rights.  The demand registration rights of the
Noteholders terminate on May 17, 1999.  Pursuant thereto, the
Company has agreed to keep any registration statement and 
prospectus filed in connection therewith effective for a
period of not less than six months.  The Registration
Agreement includes a right of the Noteholders to be
indemnified against losses due to a material omission or
untrue statement in a registration statement or prospectus
filed pursuant thereto.

     The following table sets forth certain information
regarding the beneficial ownership of shares of Common Stock
by the Noteholders as of December 31, 1995, as adjusted to
reflect the acquisition and sale of the Shares to be
registered hereby.  Other than their status as Noteholders, no
Noteholder held any position or office or other material
relationship with the Company or with Interspec during the
past three years.  As of December 31, 1995 there were
13,609,731 shares of the Company's Common Stock outstanding.

(1) Includes all Shares issuable upon conversion of the Notes
held by the Selling Shareholders.

(2) Assumes a disposition of all Shares, and retention of all
previously owned Common Stock, at the conclusion of the
offering.

(3) Includes 14,315 Shares to be issued to State Farm in

     PLAN OF DISTRIBUTION.

     The sale of Shares by the Selling Shareholders may be
effected from time to time in one or more transactions (which
may involve block transactions), in special offerings,
secondary distributions, in negotiated transactions, or a
combination or such methods of sale, at market prices
prevailing at the time of sale, at prices related to such
prevailing market prices or at negotiated prices.  Such
transactions may be effected on the over-the-counter market.
The Selling Shareholders may effect such transactions by
selling the Shares to or through broker-dealers, and such
broker-dealers may receive compensation in the form of
underwriting discounts, concessions or commissions from one or
more of the Selling Shareholders for whom they may act as
agent (which compensation may be in excess or customary
commissions).  Without limiting the foregoing, such brokers
may act as dealers by purchasing any and all of the Shares
covered by this Prospectus either as agents for others or as
principals for their own accounts and reselling such
securities pursuant to this Prospectus.  The Selling
Shareholders and any broker-dealers or other persons acting on
their behalf that participate with such Selling Shareholders
in the distribution of the Shares may be deemed to be
underwriters, and any commissions received or profit realized
by them on the resale of the Shares may be deemed to be
underwriting discounts and commissions under the Securities
Act.  As of the date of this Prospectus the Company is not
aware of any agreement arrangement or understanding between
any broker or dealer and any of the Selling Shareholders.

     At the time that any particular offering of Shares is
made, to the extent required by the Securities Act, an
amendment or a prospectus supplement will be distributed,
setting forth the terms of the offering, including the
aggregate number of Shares being offered, the names of any
underwriters, dealers or agents, and discounts, commissions
and other items constituting compensation from the Selling
Shareholders and any discounts, commissions or concessions
allowed or reallowed or paid to dealers.

Page 6



     The Selling Shareholders may from time to time pledge the
Shares owned by them to secure margin or other loans made to
one or more of the Selling Shareholders.  Thus the person or
entity receiving the pledge of any of the Shares may sell
them, in a foreclosure sale or otherwise, in the same manner
as described above for a Selling Shareholder.

     The Company intends the term of effectiveness of this
registration statement to continue for six months from the
date the registration statement becomes effective.
