A prototype instrument is presented for the indirect evaluation of the main physical parameters characterizing a mammographic X-ray beam. The instrument consists of an X-ray probe with four filtered solid-state detectors connected to a signal-conditioning electronic circuitry and a high-speed digitizer interfaced to a portable personal computer. The system, governed by an ad hoc developed software, can measure kVp, kV waveform, ripple, HVL, exposure time and exposure in a single shot of the X-ray beam with good accuracy. The system should prove very useful to any quality-control programme for mammography.

Abstract

A prototype instrument is presented for the indirect evaluation of the main physical parameters characterizing a mammographic X-ray beam. The instrument consists of an X-ray probe with four filtered solid-state detectors connected to a signal-conditioning electronic circuitry and a high-speed digitizer interfaced to a portable personal computer. The system, governed by an ad hoc developed software, can measure kVp, kV waveform, ripple, HVL, exposure time and exposure in a single shot of the X-ray beam with good accuracy. The system should prove very useful to any quality-control programme for mammography.
