Summary
A program of measurements was made to determine the spectral fluence distributions at locations of significance in a heterogeneous, hominoid phantom exposed to x rays in a manner simulating medical diagnostic radiology. The measurements were made with a specially constructed NaI(Tl) scintillation detector. The detector had a spherically shaped active volume 0.6 cm in diameter. The resolution of this detector was five times worse than that of a more conventional NaI(Tl) spectrometer. Resolution broadening and other distortions were removed from the observed pulse height spectra with a computer-coded, iterative unfolding technique. The performance of the spectrometer and the unfolding scheme was assessed by comparing, in a few cases, the unfolded NaI(Tl) spectra with spectra determined with a high resolution Ge(Li) spectrometer. The measurements were made in a physical model of an idealized representation of an average adult patient.
