Acquisition Station

Acquisition Station

acquisition provides a simple user interface to gamma camera functions including detector calibration and tuning, display of gantry position, real-time display of camera images and energy spectra, image review, definition and set-up of acquisition protocols including static, dynamic, multigated, tomographic and gated tomographic studies.

The acquisition system provides basic acquisition types with predefined default parameters and clinical acquisition protocols comprised of multiple acquisition types in a predefined sequence which come with default parameters.

Acquisition Station Hardware

PC acquisition station attached to the gantry; driven by Windows™ XP Professional Operating System
The acquisition control monitor and keyboard are integrated in the gantry structure
Five channel AD acquisition card per head simultaneously sampling the signals at the rate of 40 MHz
1024 multichannel analyzer energy channels (40-400 keV), with digitized picture binned up to 4096 x 4096 image pixels
