Abstract: A medical imaging system for detecting ionizing radiation. The system includes one or more pixilated imagers positioned to acquire patient image data and one or more position sensors positioned to acquire patient position data. Once the patient image data and patient position data are acquired, one or more processors operably connected to each of the one or more pixilated imagers and one or more position sensors calculate a three-dimensional mass distribution based on patient image data and patient position data.

Abstract: An environmentally controlled enclosure having a cable system that supports a curtain. The use of a cable system to support curtain reduces the cost to manufacture the environmentally controlled enclosure. In this regard, rather than producing an enclosure system substantially formed of steel beams, the cable system requires only a frame formed to support the cable system. The reduction in steel used to form enclosures reduces the overall cost to manufacture the enclosure. Moreover, the cable system is relatively simple in design, which reduces the time to manufacture and set up enclosure.
