Computer Aided Diagnosis and Decision Making (CAD) is becoming more prevalent in radiology departments. Many classes of exams now routinely go through a computer screening process prior to reading. One potential barrier to more widespread use of CAD screening is that the various vendors of CAD applications typically only allow their applications to run on servers or workstations provided by those companies. A clinical site that wishes to utilize, for example, mammo CAD from one vendor and lung CAD from another often is forced to acquire two different servers or workstations from the two different vendors.

The Hosted Application concept described in PS3.19 could be used to facilitate the running of multiple CAD applications from multiple vendors on the same computer system.
