Abstract: According to the present invention, there is provided a gamma camera system for brain SPECT imaging including slanted detectors with slanted hole collimators and a special hood-shaped head support device. The present invention eliminates the need for radial detector motion and therefore for collision sensing devices and safety related circuitry as required in prior art gamma cameras. Furthermore, the design and shape of the present invention reduces the necessary camera setup procedure, thereby improving camera workflow and output. The present invention's hood-shaped head support encapsulates the patient's head, preventing long hair from being entangled with the detectors while providing increased patient safety and comfort. Furthermore, the hood gently restrains the patients head, leading to less patient movement and improved image quality. In addition the hood enables very close detector proximity to the patient's head leading to further improvements in image quality.
