Abstract
&ggr;-ray emissions ( ) are detected by a rotating, one-dimensional detector array ( ). Slats of a convergent or divergent collimator ( ) are mounted between detector elements. The slats are canted by an angle &agr; from focusing on a focal spot ( ) on a perpendicular bisector to the detector array. As a detector head ( ) revolves around a longitudinal axis ( ) of the subject, the head is canted (FIG. ) to generate angularly offset data sets. Data sets with the detector array rotated to 180° opposite orientations are processed ( ) to generate a first derivative data set. Parallel lines or planes ( ) of the canted data sets are processed ( ) to generate a second derivative data set which is backprojected ( ) in accordance with the Radon transform into a three-dimensional image representation.
