When performing a patient scan to collect patient data for reconstruction into one or more image volumes, a combination nuclear-radiographic subject imaging device (10) includes first and second detector heads (22a, 22b), which move on respective positionable tracks (14a, 14b). The positionable tracks move on stationary tracks (12) coupled to a rotatable gantry structure (16). Each detector head is rotatably coupled to its positionable track by a rotation arm (24). When a radiographic scan is performed, the first detector head (22a) is rotated so that a radiographic detector (26) mounted to the first detector head (22a) faces the patient, and an X-ray source (28) mounted to the second detector head (22b) also faces the patient, opposite the radiographic detector (26). When a nuclear imaging scan is performed, the detector heads (22a, 22b) are rotated to face the patient during the scan. |
