AbstractID: 8151 Title: The use of scatter to monitor patient dose in fluoroscopy
It is becoming increasingly important in fluoroscopically guided procedures such as
interventional radiology, electrophysiology and cardiac catheterisation to monitor the
patient dose as prolonged fluoroscopic times can lead to severe radiation burns. There
are several direct and indirect methods to estimate patient dose; however most are
expensive, inaccurate or inconvenient. This paper describes a technique whereby
a compact direct ion storage device, which can be easily mounted and removed from the
x-ray housing, gives a direct measure of integrated patient exposure by measuring
scatter from the patient. This technique has been validated in the laboratory and by
comparison with dose-area product meters and film in clinical practice. This paper also
presents correlations of patient dose with exposure time and patient weight
