Chapter 10: Point Dose Calculations
Cards in this deck (5)
- 1Monitor Units (MUs)Machine output; it is calibrated to give 1 cGy/MU at a certain point (ex: dmax along CAX) under certain conditions (ex: 10x10 FS, 100 cm SSD or SAD).
- 2DoseEnergy deposited per unit mass. A point quantity
- 3MUs and DoseDifferent points inside the tissue, along the CAX, receive different amounts of dose with the same Muscle delivered. The dose at a point along the CAX depends on:
1) distance from the source (ISL)
2) depth (attenuation, energy, absorber dependent)
3) scatter (energy and absorber dependent) - 4MU Calculation (SSD Technique)
- 5MU Calculation (SAD Technique)
