Nuclear imaging apparatus

A nuclear imaging apparatus is described for producing images of an object under examination which emits nuclear radiation, comprising in combination (a) a scintillation camera for receiving the radiation and for determining the locations of scintillation events generated by the nuclear radiation, the scintillation camera issuing x and y coordinate signals corresponding to the intensity of the scintillation events; (b) display means having a screen for displaying image points under the control of the z unblank signals on screen locations determined the x and y coordinate signals; (c) means for generating a relative movement between the scintillation camera and the object along a first and a second arc-shaped scanning path; (d) transferring means generating a shift movement between the object and the scintillation camera from a first pass position to a second pass position along a linear shift direction; and (e) electronic means for enclosing a square field of view when the imaging points are displayed on the display means
