Computer-assisted radiology--requirements and solutions for digital diagnostic imaging

More and more digital imaging equipment is used in the daily routine of radiology departments. Computerized diagnostic equipment provides new capabilities for radiologists. It provides improvement of the work flow within the department, of the exchange of information between radiologists and referring physicians, and the exchange of information between radiologists specialized in specific diagnostic procedures. This exchange of information has to be performed locally within the department, between different buildings belonging to one department or between widely separated buildings in different hospital. The penetration of 'computer-assisted radiology' makes the organization of an imaging department and the information to be handled within it more and more complex. Specific requirements result from this increasing complexity. To meet these requirements, Siemens has developed technical solutions for integrated digital diagnostic imaging. These solutions allow the functional integration of physically separated systems such as multiple computed tomography (CT) units or CT plus magnetic resonance (MR) units belonging to one department, centralized archiving, hard-copy generation and image display, rapid access to images from multiple locations and effective image communication for intensive care units, child care units and trauma patients. Some of these requirements are discussed and the corresponding products are described. It is shown how these solutions will migrate to future comprehensive picture archiving and communication systems (PACS) configurations.
