NUCLEAR MEDICINE SPECT-CT MACHINE WITH INTEGRATED ASYMMETRIC FLAT PANEL CONE-BEAM CT AND SPECT SYSTEM

When performing nuclear (e.g., SPECT or PET) and CT scans on a patient, a volume cone-beam CT scan is performed using a cone-beam CT X-ray source (20) and an offset flat panel X-ray detector (22). A field of view of the X-ray source overlaps a field of view of two nuclear detector heads (18), and th...

Zusammenfassung:When performing nuclear (e.g., SPECT or PET) and CT scans on a patient, a volume cone-beam CT scan is performed using a cone-beam CT X-ray source (20) and an offset flat panel X-ray detector (22). A field of view of the X-ray source overlaps a field of view of two nuclear detector heads (18), and the offset of the X-ray detector (22) minimizes interference with nuclear detector head movement about a rotatable gantry (16). Additionally, a locking mechanism (80) provides automatically locking of the X-ray detector (22) in each of a stowed and operation position, improving safety and CT image quality.
