title: An efficient, gaseous detector with good low-energy resolution for (less than or equal to 50 keV) imaging.
abstract: An imaging detector with good energy resolution and reasonable spatial accuracy has been designed for biomedical applications. It is based on a scintillating proportional gas chamber. The energy resolution is typically 5.4% (FWHM) at 27 keV and the spatial resolution is 2.7 mm (FWHM) for 22-keV x-rays. The physical processes involved in this detector are discussed along with its main limitations and merits.
