Imaging techniques for reducing blind spots
First Claim
1. An imaging system for imaging a region of interest (ROI) of a subject, the system comprising:
- at least one orientator;
at least one translator;
at least one detector, coupled to the orientator and to the translator; and
a control unit, which is configured to;
during a first portion of an image acquisition procedure, drive the translator to position the detector in a first position, and, while the detector is thus positioned, drive the orientator to orient the detector in distinct angular orientations with respect to the ROI, by orienting the detector at only a portion of the distinct angular orientations during an initial sweep of the detector, and at remaining distinct angular orientations during a subsequent sweep of the detector, andduring a second portion of the image acquisition procedure, drive the translator to position the detector in a second position, and, while the detector is thus positioned, drive the orientator to orient the detector in distinct angular orientations with respect to the ROI.

Abstract
An imaging system is provided for radioimaging a region of interest (ROI) of a subject. The system includes a housing, a support structure, which is movably coupled to the housing, and at least one motor assembly, coupled to the housing and the support structure, and configured to move the support structure with respect to the housing. The system also includes at least two detector assemblies, fixed to the support structure, and comprising respective radiation detectors and angular orientators. A control unit drives the motor assembly to position the support structure in a plurality of positions with respect to the housing, and, while the support structure is positioned in each of the plurality of positions, drives the orientators to orient the respective detectors in a plurality of rotational orientations with respect to the ROI, and to detect radiation from the ROI at the rotational orientations. Other embodiments are also described.
