Tissue in front of the affected area in the body as the beam comes in will be dosed with radiation at a high level as well. If it always comes from the same direction (if you had one beam) then the same tissue is affeted so the damage is concentrated in one area, but also the dose to the tumour is uneven as the xrays will lose energy and effectiveness as they move through the body. If you add more beams, you target the tumour from more directions, making the dose to the tumour more even but also spreading out the damage to healthy tissue over more of the body, so no healthy tissue is affected severely
goated physicist
Thank you
how much valuable will be automating the medical image segmentation part for this hole process of radio therapy?
Good presentation
What program is used to process these images?!
very nice presentation
Why was it necessary to add more beams?
beams are the solution for everything
To decrease concentrated dose to normal risk organs
