Medical physics Interview Question:

What is dose Calculation Matrix?

Submitted by: Muhammad

The area in the 3D treatment planning system that dose is calculated. It is split into units called voxels (indicating a volume, hence 3D). The higher the resolution (smaller the voxel size) the more accurate the dose calculation, however, the trade off is a longer period of time to make the calculation as there are now more voxels to calculate.
