Abstract: In some embodiments, a safety system for a close range scanning machine inhibits collision of moving detector heads with a patient or other object. For example a proximity sensor and/or a collision sensor may guide to bring the head close enough to a patient and/or warn to prevent a collisions and or reduce impact. Parts that are in that are in the FOV of the detector may be transparent to the detected signal and/or uniformly affect the signal, facilitating identification of the source of the signal from the detector. In some embodiments, a dynamic motion restrictor is set during scanning according to the desired scanning position and/or the position of the patient. In some embodiments, a motion restrictor acts to prevent unbalanced motions.

Abstract: An N-M tomography system comprising: a carrier for the subject of an examination procedure; a plurality of detector heads; a carrier for the detector heads; and a detector positioning arrangement operable to position the detector heads during performance of a scan without interference or collision between adjacent detector heads to establish a variable bore size and configuration for the examination. Additionally, collimated detectors providing variable spatial resolution for SPECT imaging and which can also be used for PET imaging, whereby one set of detectors can be selectably used for either modality, or for both simultaneously.
