ELGEMS, 一个 wholly-owned subsidiary of GE Medical Systems, was searching for the means to reduce production costs in its Millennium VG series Gamma camera, while at the same time maintaining top accuracy and efficiency.
The Millennium VG camera performs highest-quality functional anatomic mapping. It contains a complex array of devices that enable the patient to sit or lie on a movable table while the camera performs real-time automatic body contouring. Imaging is performed by two Nal detector assemblies with high-precision collimators mounted on the gantry. The collimators incorporate variable geometry detectors that feature 90° and 180° positioning for complete anatomical coverage.
In order to control the various motors driving the movable table and the adjustable collimators along the various axes, several drive controllers were needed. Such a configuration tended to be both costly and space consuming. What was needed was a compact and cost-efficient assembly of m that could concurrently control the scanner motors while guaranteeing the highest level of reliability and functionality.
