Clinical application
Benefits of CBCT compared to 2D x-Ray imaging
•
Match in 3D
•
See anatomical changes
•
Visual verification of target coverage
Drawbacks
•
Not as easy to include the imaging dose in the treatment plan
–
Could be more than 1 Gy for a 30 fraction treatment
•
Time
–
Both acquisition and reconstruction takes time
But MRI has potential to provide better soft tissue contrast, real
time imaging without any dose, so why not go for that?
