Abstract:
Apparatus for acquiring tomographs of a subject, the apparatus comprising a pair of plane scintillation detectors (1, 2) carried by a support (32) rotatable about an axis of rotation (4), and connected to an image processor (90-94), the apparatus being characterised in that:the two detectors are secured to each other,the detection fields (7, 8) of these two detectors are inclined at an angle relative to each other;the bisector plane (11) bisecting the angle formed between these detection fields includes the axis of rotation;and in that the apparatus includes:means (35-42) for displacing the pair of detectors together relative to the subject in a direction (13) which is radial to the axis of rotation; andmodification means (94) for modifying an effective detection field (98) of these detectors as a function of said displacement.
