ABSTRACT:
Computerized tomographic apparatus is described in which a radiation source and an associated detector array execute, concomitantly, reciprocating lateral scanning movements and rotational scanning movements relative to a patient's body, the scanning movements being effected in the plane of a cross-sectional slice of the body which intersects the patient's heart. The patient is located so that the heart is substantially at the center of the scanning movements. The lateral movements are substantially sinusoidal, arranged so that a substantially linear portion of the movement occurs when the source irradiates the heart, and the rotational movement is continuous or substantially continuous and any pauses are only brief, and during alternate lateral scans when the aforementioned substantially linear portions of movement occur. The scanning movements are synchronized to the patient's heart beats so that the heart is irradiated during a quiescent phase of its movement.
