Abstract:
An imaging system for generating SPECT images, the system for use with a table positionable to support an object to be imaged within an imaging area, the table capable of vertical and lateral movement to position the object within the imaging area in required positions relative to SPECT cameras, the system for minimizing the degree of table movement necessary to achieve the required positions, the system comprising:a gantry formed about a rotation axis through the imaging area; andfirst and second cameras having first and second camera axis which pass through first and second camera fields of view, respectively;wherein, each of the first and second cameras is mounted to the gantry for radial movement relative to the rotation axis and for rotational movement about the rotation axis, the cameras positionable on the gantry in at least an opposing position wherein the second camera opposes the first and the camera fields of view are aligned and an L position wherein the first and second camera axis intersect at an intersection point and essentially form an L and neither camera blocks the field of view of the other camera, the cameras mounted such that when in the L position the camera axis intersection point is further than the rotation axis from each of the cameras thereby enabling the cameras to be moved radially inward while still maintaining identical distances from the rotation axis to reduce the distance between the rotation axis and each of the cameras.
