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