MEASUREMENT OF TMR AND PDD - Scott Crowe

SpletPercentage depth dose (PDD) is a quotient used in medical physics to measure the dose at a specified depth compared to the depth where dose is maximum.1 Thus, the equation: ρ = Dd/Dmax x 100. where Dd is any depth and Dmax is the depth of maximum absorbed dose shows this relation.1 The PDD is a percentage so it is multiplied by 100. SpletStep 1 Open the PDD curves in myQA Accept - Data Window and Rescale all the PDD curves to Dose Maximum at 100%. Step 2 Go to Common Settings > Calculations > Click Depth Dose Vs. Field Size tables. Create New Template and Change the Template Name. In Details Section Change the Resolution of the Depths in a manner convenient to you. recovered翻译

TMR point measurements were measured with a Wellhofer tank and Edge detector, at multiple depths from 0.5 to 20 cm and 100 cm SDD. PDDs for converting to TMR were scanned with a Wellhofer system and SFD detector.

SpletIn this study, zero-field percent depth dose (PDD) and tissue maximum ratio (TMR) for 6 MV x rays have been determined by extrapolation from dosimetric measurements over the field size range 1 x 1-10 x 10 cm2.
