Abstract
The XERG (Xonics-Electron-Radio-Graphy) system is the first ionographic system (High-Pressure-Gas-Iono-graphy) suitable for clinical application which became available for testing. The basic principle, the function and imaging qualities of the XERG system are described and first clinical experiences reported. The XERG mammogram is a transparent X-ray negative image, the image quality of which is characterized by good general image contrast, a moderate edge-effect and a high quantum-noise level but giving an extremely low dose rate (4.5% compared to screenless mammography film). Although the XERG quality is not satisfactory in contact technique, it yields results which are equal in quality, when using a 1.5-fold magnification technique, to the results obtained with screenless film mammography at one-tenth of the dose, and is superior to any commercially available film-screen system. Hence, in our opinion, the XERG mammography system is a step forward towards high-quality low-dose mammography.
