Image guided radiotherapy
Today, using advancements in digital imaging devices, the use of image guided radiotherapy portal imaging has developed into both a tool for accurate field placement and as a quality assurance tool for review by image guided radiotherapy oncologists during check film reviews. This section does not any. Often, a patient will receive corrections to their treatment via on-line strategies during their first radiation session, and physicians make subsequent adjustments off-line during check film rounds. Tolerance of normal tissue to therapeutic irradiation. Advances in Image-guided Radiotherapy - The Future is in Motion. If not all of the radiation beam is absorbed or scattered in the patient, the portion that passes through may be measured and used to produce images of the patient. Onc, 2007 Zhang et al,IJROBP, Vol. The patient is localized in the treatment room in the same position as planned from the reference imaging dataset. The British Journal of Radiology. Escalated-dose versus standard-dose conformal radiotherapy in prostate cancer: first results from the MRC RT01 randomized controlled trial.
By aligning the markings with the radiation field or its representation in the radiation therapy treatment room, the correct placement of the treatment field could be identified. Long-term results image guided radiotherapy the MD Anderson randomized dose-escalation trial for prostate cancer. A test unit using a single linear detector, consisting of 75 cadmium tungstate crystals, was mounted on the linear accelerator gantry. Current reviews of Electronic Portal Imaging Devices EPID show acceptable results in imaging irradiations and in most clinical practice, provide sufficiently large fields-of-view. Such changes can include tumor shrinkage or expansion, or changes in shape of the tumor and surrounding anatomy.
Onc, 2007, 17: 268. Both serve their purposes in the clinical setting, and have their own merits. Proceedings of the 49th Conference of the Particle Therapy Co-Operative Group PTCOG. This article is about radiation therapy, including EPID as Electronic Portal Imaging Devices. The effect of amorphous silicon EPID spectral response on the dosimetry of IMRT beams. One such factor is uncertainty in patient position on the treatment unit.

Onc, 2007, 17: 268. Alternatively, products such as AlignRT from Vision RT allow for real time feedback by imaging the patient directly and tracking the skin surface of the patient. Analysis of prostate patient setup and tracking data: potential intervention strategies.
