摘要： A curved beam apparatus adapted for mounting thereon a scintillation detector. The apparatus comprises a circular C-arm which is balanced with a counterweight at one end and a scintillation detector pivotally mounted by means of a yoke at the other end. The C-arm is mounted in a carrier member which in turn is attached to a base. The carrier member is rotatable about an axis passing through its center. In addition, the C-arm rotates circumferentially along a plane defined by the shape of the C-arm and intersecting said axis. The combination of the rotation of the C-arm and the rotation of the carrier member permits the scintillation detector to be quickly and easily manually positioned to any desired location on an imaginary sphere surrounding a portion of patient to be examined.

摘要： A radiation imaging system including a rotatable scintillation detector (50) for non-circular emission computed tomography. The radiation imaging system includes a rotatable scintillation detector (50) and a linearly movable detector stand (10). With the stand (10) stationary, the scintillation detector (50) is capable of circularly orbiting about the longitudinal axis of the patient for emission computed tomography and with the detector (50) stationary the detector stand (10) may be linearly displaced for whole body scanning with the patient aligned parallel to the detector stand path in an orientation orthogonal to the tomographic orientation. The circular rotational motion is combined with the linear translation such that the detector (50) orbits about a section of the patient in a non-circular path. The path assures a minimum distance between the face of the scintillation detector (50) and the boundary of the patient during the entire tomographic orbit to thereby improve resolution of the tomogram.
