Abstract
Two noninvasive methods of measuring half-value-layer (HVL), the ring and localization techniques, were evaluated and compared with an invasive technique to determine accuracy and reproducibility. Both noninvasive techniques were accurate and reproducible at isocenter. However, the measured HVL was dependent upon the bowtie filter and the location of the ionization chamber with respect to isocenter.
