An efficient, gaseous detector with good low-energy resolution for (less than or equal to 50 keV) imaging.
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.
