A nuclear medicine tomography system comprising: a detector carrier having a circular or partially circular aperture and defining a plane; a plurality of SPECT detector assemblies attached to the detector carrier and arranged around the aperture; a patient carrier movable relative to the plane; each detector assembly comprising an arm defining an extension axis and at least one detector head movable along the axis, wherein each detector assembly has a rounded distal portion; wherein each detector head is extendible along the axis, from the detector carrier toward the patient carrier; and a controller to: control, based on desired bore size and shape, extension and retraction of the detector heads to a spatial arrangement defined by the extension and retraction, control data acquisition by the detector heads, and control image reconstruction of acquired data; the controller further configured to control data acquisition and/or image reconstruction, based on the spatial arrangement.

Gantry rotation

Methods for calibrating a Nuclear-Medicine (N-M) imaging system including calibrating an N-M imaging system scanning unit for scanning detector uniformity map and energy resolution as well as generating an angular orientation map of a plurality of scanning units and a line source of radiation. There is further disclosed a jig for holding a line source during a calibration process of an N-M imaging system.

Calibration and quality control of a nuclear-medicine (N-M) radio imaging system

A nuclear medicine tomography system including: a detector carrier; a detector carrier housing including an inner space; a plurality of detector units, coupled to the detector carrier, each detector unit comprising: a detector camera; a cooling channel which guides air to the detector camera from the inner space; an exhaust channel which guides air from the detector camera to the inner space; a heat pump configured to cool air within the inner space.

Nuclear medicine tomography system comprising a detector carrier housing and a heat pump configured to cool air within the detector carrier housing

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.

Proximity detection

Counterbalancing of detectors for nuclear medicine tomography systems

A Nuclear Medicine (N-M) imaging system including a gantry having a stationary stator and a rotor rotatably mounted on the stator and including detection units. The rotor is driven by a rotor driving assembly including a linear encoder. The detection units mounted on the rotor include scanning columns having one or more Multi-Pixel Photon Counter (MPC) mounted on one or more extendable arm. The gantry also includes flat cables connecting the controller with gantry components, e.g., the scanning column Multi-Pixel Photon Counters (MPC). The scanning columns are pivotably moveable by a scanning column driver system including a rotary encoder.

Moving parts in a nuclear medicine (N-M) imaging system

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.
