How a Linear Accelerator Functions – Video Reveals an Elekta Synergy utilized for Radiation Treatment.

A direct accelerator produces a beam of either electrons or very high energy X-rays. The radiation beam can be shaped and directed to match the growth shape. The beam of radiation is directed on to the patient within a precision of 2mm. This is accomplished by a mix of:.
– control and shaping of the X-ray beam.
– accurate patient positioning with respect to the X-ray beam.
Shaping of the beam can be achieved in three ways:.
– usage of the main and secondary collimators. These are large tungsten blocks which can form the X-ray beam into the suitable square shape.
– custom-made obstructs– these are cast blocks which are specifically for an individual patient to shield delicate tissue or structures and can be made to the specific shape.
– Multileaf Collimator (MLC)– these are great leaves (usually1cm large) that are computer-controlled to match the shape of the tumor. Usage of MLC is now typical practice in many countries.
