Backscatter factors in the mammographic energy range.
Backscatter factors for kVps and half-value layers typical of mammographic beams have been determined as a function of beam diameter and half-value layer. The method utilized thin TLD-100 chips with the scattering medium alternately present and absent. Results indicate that the field-size dependence of the backscatter factor for lower half-value layers is less than that shown in the British Journal of Radiology Supplement 11.
