A radiographic three dimensional imaging apparatus capable of focusing on a center of rotation point, includes at least two gamma ray detectors, each having a radiation input face, with each detector positioned on a linear path, wherein each detector is movable along the detector’s linear path, while simultaneously swiveling to maintain the detector’s input face towards the rotation point. The apparatus is adjustable to conform to the needs and dimensions of individual patients and the surgical procedure to be performed. By properly removing a portion of the printed circuit board, the electronic component can be exposed. The adjusted data are used to print a new hardcopy.
