A method and apparatus for detecting radiation including x-ray, gamma ray, and particle radiation for radiographic imaging, and nuclear medicine and x-ray mammography in particular, and material composition analysis are described. A detection system employs fixed or configurable arrays of one or more detector modules comprising detector arrays which may be electronically manipulated through a computer system. The detection system, by providing the ability for electronic manipulation, permits adaptive imaging. Detector array configurations include familiar geometries, including slit, slot, plane, open box, and ring configurations, and customized configurations, including wearable detector arrays, that are customized to the shape of the patient. Conventional, such as attenuating, rigid geometry, and unconventional collimators, such as x-ray optic, configurable, Conpton scatter modules, can be selectively employed with detector modules and radiation sources. The components of the imaging chain can be calibrated or corrected using processes of the invention.

A ball grid array presentment apparatus and associated method are provided. The apparatus has a stationary guard defining a first passage. A core is mounted adjacent to the stationary guard, the core being operably moveable between an unload position and a second position. The core defines a second passage and supports a workpiece fixture operably retaining the ball grid array. The unload position of the core operably aligns the second passage to the first passage, the aligned passages being sized to permit access to unload the ball grid array from the workpiece fixture. The second position of the core operably misaligns the second passage from the first passage whereat the core and the stationary guard cooperatively form an enclosure around the workpiece fixture containing a supply of balls that are not retained in the ball grid array.
