Virtual CT simulation

All treatments are planned and calculated on the bases of CT images of the patient in the same position he/she will be in on the accelerator table. Therefore, maximum reproducibility of treatments is guaranteed.

Advantages: MD Anderson Madrid Radiation Therapy Service uses a GE VCT 64-slice CT scanner capable of taking whole-body images in just a few seconds. 4D CT scan studies, in which over 1,000 images are reconstructed, take under a minute to do.
