An improved image acquisition system allows the angular displacement between two detectors to be adjusted between 90&deg; and 180&deg; to reduce the imaging time for both 360&deg; and 180&deg; scans. A patient table is displaced vertically and horizontally from a lateral axis to allow the body of a patient to be positioned next to the detectors and to improve resolution.

Adjustable dual-detector image data acquisition system

The imaging system has two detectors which can be rotated in a circular path about an object with the angular displacement between the detectors and their radial position with respect to the axis being adjustable. Preferably, the distance of the detectors from the lateral axis is adjustable to increase resolution of the system. A gantry has supports for drive gear rings for the detectors with radial motion mechanisms connecting one detector to the interior surface of a drive gear ring and the other to the exterior of its drive gear ring via a support arm. A drive gear and idler gear move one detector along the circular path and a radial drive motor moves the detectors radially with respect to the axis.

An improved image acquisition system allows the angular displacement between two detectors to be adjusted between 90.degree. and 180.degree. to reduce the imaging time for both 360.degree. and 180.degree. scans. A patient table is displaced vertically and horizontally from a lateral axis to allow the body of a patient to be positioned next to the detectors and to improve resolution.

An image data acquisition system for performing SPECT imaging and other types of imaging used in nuclear medicine includes an assembly of three detectors and a mechanical system for adjusting the relative angles of the detector image direction arrows, displacing the individual detectors along the image direction arrows, and rotating and displacing the detector assembly.
