Abstract: In certain embodiments, an interactive diagnostic display system comprises a database, a digital data processing device, and a display. The database includes: (1) diagnostic data based on measurements of one or more characteristics of a patient's body; (2) denoising algorithms, each corresponding to a value of a denoising parameter; and (3) enhancement algorithms, each corresponding to a value of an enhancement parameter.

Abstract: In preparation for a scan, a camera head (B) is positioned (30, 32, 34, 36) about a patient on a patient table (20) to determine the minor axis (54) and major axis (56). Based on a comparison (60) of a difference in the major and minor axes with preselected standards (62a, 62b, . . . ) one of a corresponding plurality of correction factor tables (64a, 64b, . . . ) is selected. During a scan as the camera head is rotated about the patient by an angular position clock (70). The radial distances of the camera head from the scan center are calculated (72, 74, 78) which cause the camera head to follow a generally ellipsoidal path. The size of the ellipse is adjusted (74, 78) in accordance with the major and minor axes. At each of a plurality of angular positions, the enabled correction factor table is addressed by the angular position and a corresponding correction factor is combined (80) with the radius. In this manner, the shape, as well as the size, of the orbit is adjusted.
