IGRT - Image guided radiation therapy

IGRT - Image guided radiation therapy.

IGRT is a radiation therapy with a help of imaging. This is useful because of the variation of tumor after each treatment and the difference of patient position.

In an article about contour extraction and compression of Andrzej Dziech, there are many methods to export contour of image.

Virtual Wedge of Siemens


The use of wedge filters in radiotherapy to produce dose gradients across the beam profile is widespread.

Traditionally this is done using physical wedges made of metallic material shaped in such a way so as to produce graduated attenuation across the radiation beam.

Controlling the movement of one of the collimator jaws and the delivered dose rate throughout irradiation can produce similar beam profiles.

The Siemens Virtual Wedge™ uses this philosophy to replace physical wedge filters.
