Interventional Oncology Suite at University of Wisconsin Hospital, equipped with 4-slice GE Lightspeed scanner and GE Smart-Step technology

The Department of Radiology currently operates 6 state-of-the-art helical CT scanners. Five of these scanners are GE Lightspeed units (GE Medical Systems, Milwaukee, WI), and all are equipped with multiple detectors. One of these scanners is equipped with Smart-Step, which allows three consecutive images to be taken at low dose radiation for interventional procedures (GE Medical Systems, Milwaukee, WI). A PACS system with three independent workstations for image reconstruction and cine mode viewing (ALI GLx) are present in adjacent reading rooms and two Advantage Windows workstations are used for 3D-reconstruction. A new 1050 GSF small animal imaging suite is currently under construction in the K4 animal facility in the Clinical Science Center and is slated for occupancy in January of 2005. Located in the Contrast Agent Development Lab is a first generation MicroCAT-1 (ImTek, Inc, Knoxville, TN) scanner. Coupled with sophisticated Amira (TGS Inc, San Diego, CA) 3D-image processing software, the unit is capable of simultaneous multiplanar as well as 3-dimensional reconstruction.

The Department of Radiology has 10 clinical ultrasound units: four Phillips IU-22, three GE Logiq 9 with Breakthrough 2005 software, three Sequoias with software version 8.5 from Seimens. All units have color Doppler velocity and energy modes. The systems are linked via a McKesson (ALI) 5.0 Radstation and a Sono Station 5.0 PACS system with softcopy workstations. An upgrade to McKesson Version 11 is expected when it becomes available in March 2006.
