The Scans and Dummy run
Following the successful creation of your mask, you are taken to the CT scanner. This is another room with a large white machine resembling a doughnut with a table in front.
From the scans the radiographer and/or consultant then plots the areas to be treated and calculates the direction of the beams for your radiotherapy.
A few days after your scans, once all the information has been analysed and marked up, you are called back for the dummy run.
This is a run through to check everything and gives you a good idea of what to expect when having the treatment. Although not recieving any treatment at this point, you are placed on a radiotherapy machine which takes an x-ray scan. This allows the staff to check all the markers and calculated directions.
Again you lie on the table with a support under your legs and your head resting on a cradle after which your mask is put over you and clamped to the table. The radiographers then line up the laser beams with the markers on your mask and the machine is set to go.
