IMRT often requires multiple treatment sessions or divided. There are several factors to take into account when determining the total number of sessions of IMRT and dose of radiation. The oncologist takes into account the type, location and size of the malignant tumor, doses to critical normal structures, and the patient’s health. Typically, patients are scheduled for IMRT sessions five days a week for five to eight weeks.

At the beginning of the treatment session, the therapist places the patient on the table and guided to the skin tags that define the treatment area. If you have molded devices are used to maintain the patient in the proper position. You may have to place the patient in another position during the procedure. Imaging systems in the treatment machine such as x-rays or CT can be used to verify the positioning and location markers. Read the rest of this entry »
