The Use of Ultrasound Imaging in the External Beam Radiotherapy Workflow of Prostate Cancer Patients

Abstract EN

External beam radiotherapy (EBRT) is one of the curative treatment options for prostate cancer patients.

The aim of this treatment option is to irradiate tumor tissue, while sparing normal tissue as much as possible.

Frequent imaging during the course of the treatment (image guided radiotherapy) allows for determination of the location and shape of the prostate (target) and of the organs at risk.

This information is used to increase accuracy in radiation dose delivery resulting in better tumor control and lower toxicity.

Ultrasound imaging is harmless for the patient, it is cost-effective, and it allows for real-time volumetric organ tracking.

For these reasons, it is an ideal technique for image guidance during EBRT workflows.

Review papers have been published in which the use of ultrasound imaging in EBRT workflows for different cancer sites (prostate, breast, etc.) was extensively covered.

This new review paper aims at providing the readers with an update on the current status for prostate cancer ultrasound guided EBRT treatments.
