ELEKTA AND IMPAC MEDICAL SYSTEMS AGREE TO JOINTLY DEVELOP DICOM-RT

LINEAR ACCELERATOR INTERFACE

Interface will be the first complete linear accelerator DICOM-RT

interface and will facilitate connectivity between Elekta's digital

linear accelerators and IMPAC's Oncology Management System

Elekta, a world-leading supplier of advanced and innovative radiation

oncology solutions and services, and IMPAC Medical Systems, Inc.

(NASDAQ:IMPC), a leading provider of information management solutions

for cancer care, announce today their agreement to use a full DICOM-RT

compliant specification for the development of an interface to connect

the Elekta product lines of digital linear accelerators (Elekta

Synergy(TM) and Precise Treatment System(TM)) with IMPAC's oncology

information management products.

This interface will provide a vendor-independent means of facilitating

universal connectivity of next-generation radiation treatment devices,

such as linear accelerators and proton therapy delivery systems as well

as treatment simulation devices to information management systems. IMPAC

and Elekta are the first to formally adopt the standard. Both companies

have been working together towards this goal over the past months.

"This agreement will further improve seamless connectivity for

customers by expanding the use of new technology systems as well as

shorten the start-up time for new and expanding cancer centers ," stated

Tomas Puusepp, Executive VP Sales, Marketing & Service at Elekta. "More

importantly, patients will benefit from a more rapid deployment of

leading edge treatments. We encourage all oncology vendors to join

Elekta and IMPAC in adopting this standard."

"This is a collaborative development effort aimed at improving the

process of managing increasingly complex cancer treatment techniques,"

stated Joseph K. Jachinowski, president and CEO of IMPAC. "IMPAC is

delighted to team with Elekta in this agreement to adopt the DICOM-RT

standard in a complete manner," he added.
