Abstract

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.
