Imaging apparatus comprising a ring-shaped gantry

摘要

An imaging apparatus having a ring-shaped gantry is provided. The gantry has a rotor arrangement rotating therein and a radiation source as well as at least one radiation detector. The gantry has at least one gantry segment which can be detached from the ring shape to allow the gantry to be opened laterally. The gantry is arranged on a supporting structure so as to be movable in space. The supporting structure is a ceiling-mounted stand having at least two degrees of freedom of movement. The gantry has at least two radiation sources disposed offset by an angle on the rotor arrangement and associated with each of which is at least one radiation detector.

1. An imaging apparatus, comprising:
a ceiling-mounted stand having at least two degrees of freedom of movement; and a ring-shaped gantry arranged on the stand to be moved in space comprising:
a rotor arrangement rotating in the gantry,at least two x-ray radiation sources disposed offset by an angle on the rotor arrangement, andat least two x-ray radiation detectors each associated with each of the x-ray radiation sources, wherein the gantry comprises at least one gantry segment which can be detached from the gantry to allow the gantry to be opened laterally, and wherein the gantry is rotatably mounted on the stand by a revolute joint having at least one degree of rotational freedom, and wherein the revolute joint is arranged such that the gantry is rotatable in a first direction and pivotable in a second direction different from the first direction about a common axis extending through the revolute joint.
