Summary

Physics Prior¶

We have updated the model with a special gaussian tube, which is a continous line along the gantry angle and a gaussian decay in every other direction. This forces the model to concentrate in this section. Additionally we added a similar prior, but it estimates a possible endpoint for the beam energy deposition, making it easier to learn.

The model backbone is just a simple Encoder->Transformer->Decoder pipeline inspired by DoTA.

Mechanism

Since this algorithm was designed for the DoseRad Challange it takes CT images, initial energy and ray source/target pairs that are used to generate the priors.

Interfaces

This algorithm implements all of the following input-output combinations:
