This program instructs PET Technologists and Physicians in the operation and clinical application of the AW Workstation Cortex ID. Instruction is delivered by a GE PET Applications Specialist at the customer's facility. The training produces the best results when 1 to 4 Technologists are dedicated to the complete training session. It is also critical that key physicians are available to review processing protocols and images. In addition, the patient schedule should be modified as indicated in the agenda to allow time for instruction.
