Dosimetry Competency Form

Record and Verify Competency

The goal is to have a solid working foundation of the tools available in the system

 Record and Verify System: MET UNMET COMMENTS Enter simulation fields Enter treatment fields Primary dose tracking Secondary dose tracking Troubleshoot dose tracking problems Dose action points When to use Add dose action point Acknowledge dose action point Manually record treatments Necessity Document reason Treatment calendar Create new treatment calendar Changing treatment calendar Schedule films Dose tracking Schedule unusually patterned treatments Prescriptions Information needed Signatures Images

Calculation Competency
The goal is to understand factors involved in MU and dose calculations. Students are expected to be proficient in mu calculations for all types of fields.

 Calculations: MET UNMET COMMENTS Interpolation Single fixed SSD MU calculation Extended distance MU calculation Mayneord F factor Inverse square Given dose Dose to a point Bolus Transmission factors SAD MU calculation Weighted fields Mixed energy fields Normalization Bolus Transmission factors Electron MU calculation Extended distance MU calculation Bolus Cutouts Pb shielding on skin Rotational field MU calculation understanding the difference when calculating for rotational fields: average TAR and MU/degree Equivalent square Unblocked field Blocked field Clarkson Calculation – When it is used Candidates must demonstrate competence calculating doses for each of the following treatment set-ups Single, Open Field Parallel Opposed Fields with Blocks Geometric Gap Weighted Fields Wedged Fields Computer Generated Isodose Plan Electron Field

Treatment Planning Competency
The goal is to understand treatment planning techniques, what makes a valid plan vs. a nontreatable plan.

Students should understand the effect of beam modifying devices through hands on learning. Students should be

able to interpret information in a plan.

 Treatment Planning: MET UNMET COMMENTS Contours Normal tissue CTV, GTV, PTV, ITV Beams Beam parameters Independent jaws Split beam Beam modifiers Use of MLC vs cerrobend and limitations Use of hard wedges vs EDW and limitations Beam weighting Prescription Normalization Isodose lines Goals Dose Target volume Normal tissue tolerance 2-D planning 3- D planning Breast/CW tangents Breast/CW with bolus 3 0r 4 field Breast Lung Pelvis Rectum IMRT H & N Prostate Gyn Cumulative plans What they are When they are needed DVH Interpreting the information DRRs Generate DRRs Generate electron cutouts Documentation Secondary MU calculation Plan check IMRT QA Plan approval In planning system In record and verify system

Mould Room Competency
The goal is to learn about different techniques used in patient setup and treatment through actual

involvement in the design and creation of blocks, bolus, etc.

 Blocks, Bolus MET UNMET COMMENTS Create cerrobend Photon and electron blocks in planning system Cut cerrobend photon and electron blocks Aquaphor bolus Superflab Custom bolus Moulds
