N2 - We have designed prototype control electronics and software responsible for moving adjustable pinhole apertures. With this design we can create various imaging configurations corresponding to desired resolutions and sensitivities in a large imaging system. AdaptiSPECT-C is a dynamic whole-brain imager composed of 24 cameras, each outfitted with five apertures. This system can be adjusted in real-time as part of the data acquisition method for dynamic studies to account for changes in the source activity as a function of time. The control electronics for these apertures are designed to operate a single camera in the assembly and each camera can function independently. The modular design allows movement of multiple apertures for fast setup times and storage of preset configuration for ease of repeatability. The software also handles user input for troubleshooting.
