2. CT Subsystem: 64-slice diagnostic CT with a Performix tube.
3. Gantry Bore: 70 cm wide-bore design to maximize patient comfort and reduce anxiety.
4. Power Output: 100 kW nominal input power.
5. Patient Table: Supports a weight capacity of up to 500 lbs.
6. Computing Platform: Powered by an IBM BladeCenter for ultra-fast, high-volume data processing.

Advanced Imaging Technologies

1. Time-of-Flight (ToF) Architecture: Implements VUE Point FX intelligent reconstruction, which measures the precise arrival time of photons. This heavily reduces background noise and improves lesion contrast.
2. MotionFree Imaging: Features specialized motion management applications such as MotionMatch and Motion VUE. These tools align gated PET and CT studies to minimize blurring caused by patient respiration or cardiac cycles.
3. Point Spread Function (PSF): Uses advanced algorithms to correct geometric distortions at the edges of the field of view, maintaining sharp spatial resolution across the entire scan area.
