8.4 - Photon Beam Modification

There are several techniques used to alter a standard, square photon beam incident on a patient.

Techniques

• 8.4.1 - Field Size Modification (MV Photons)
• 8.4.2 - Field Size Modification (kV photons)
• 8.4.3 - Compensation (Photon Beams)
• 8.4.4 - Shielding Of Organs At Risk
• 8.4.5 - Modification Of Skin Dose Photons
