The impact of networking on image acquisition system design.

Widespread integration of networking technology will change the hospital imaging environment, making computational, archiving, and film production services available to network-connected modalities. This change will be reflected in the designs of the image acquisition modalities themselves. A view of the future is presented in which the modalities depend on network-provided services, simplifying the modalities' designs and making them more cost-effective. Achieving this view will require cooperative efforts by standards groups, PACS and modality manufacturers, and hospital organizations.

Computed tomography/guided stereotactic surgery: conception and development of a new stereotactic methodology.

Computed tomography (CT) has become the first modality to provide the patient's self-brain map for stereotactic neurosurgery. This paper describes our development of a nearly artifact-free stereotactic frame designed for CT imaging. The surgical procedure is performed within the CT scanner itself. The scanner's computer, via a new software program, spatially integrates the new stereotactic frame with the CT images of the patient and with the scanner gantry to provide rapid coordinate determinations, calculate potential probe trajectories, obtain target accuracy within 1 mm, and observe for any procedural complications. Our initial clinical experience with this system is described.
