Instrumentation in positron emission tomography.
The past 40 years have seen PET scanning evolve from a tool that was used predominantly for research to a valued clinical, imaging modality. Current PET scanners must perform high quality, whole-body, as well as brain, PET. There are several levels of PET devices that range from the dedicated, high-end scanners down to the hybrid PET-SPECT systems that offer varying levels of performance. The incorporation of PET into single, hybrid, multi-modality units that can provide functional and anatomic information is becoming extremely popular. Several manufacturers now provide hybrid PET-CT scanners. There is also a growing interest in dedicated devices for specific applications, such as high-resolution scanners for imaging small animals.
