Overview Radiation therapy Open pop-up dialog box Close. Radiation therapy External beam radiation uses high-powered beams of energy to kill cancer cells. Request an Appointment at Mayo Clinic.
External beam radiation therapy Open pop-up dialog box Close. External beam radiation therapy During external beam radiation therapy, you're positioned on a table and a large machine moves around you sending beams of radiation into precise points in your body.

What is Winston Lutz test? For instance, the cone-beam computed tomography CBCT technology available on the modern day linacs allows acquiring 3D images of the patient's head in the treatment position. What is wedge factor? I am a bit confused in definition of wedge factor.
KHAN defines it as the ratio of the doses with and without the wedge, in a phantom at a suitable depth beyond the depth of maximum dose.
Podgorsak defines the ratio usually at Dmax. What is DMAX radiotherapy? When a radiation beam interacts with tissue, a certain depth of tissue is required before we see the maximum amount of radiation maximum dose or dmax.
What is enhanced dynamic wedge? Enhanced dynamic wedges substitute the physical wedges. This technique achieves wedge-shaped dose distributions by computer-controlled movement of one of the collimator jaws Fig.
What is PDD in radiotherapy? In radiotherapy, a percentage depth dose curve PDD sometimes percent depth dose curve relates the absorbed dose deposited by a radiation beam into a medium as it varies with depth along the axis of the beam.
You may get to a point during your radiation therapy when you feel too sick to work. Talk with your employer to find out if you can go on medical leave.
Check that your health insurance will pay for treatment while you are on medical leave. Menu Contact Dictionary Search. Understanding Cancer.
