A single-ring positron camera has been completed to the point where a variety of different objects have been imaged. This includes the construction of six position-sensitive single-crystal detectors with their associated electronics, the data acquisition system which acquires data simultaneously from nine possible coincident pairs of detectors, and the necessary software to reorganize the data into the appropriate format, reposition scintillation events to account for nonlinearities in the detectors, and reconstruct a transverse section image using a filtered backprojection algorithm. A spatial resolution below 8 mm full-width-half-maximum (FWHM) has been measured; other performance parameters have yet to be determined.
