dosemodulated

Dosemodulated refers to a technique used in radiation therapy where the radiation dose delivered to a patient is adjusted during the treatment course. This adjustment is based on real-time information about the tumor or surrounding tissues. The goal is to optimize the therapeutic effect by delivering a higher dose to the tumor when it is most responsive, or to reduce the dose to healthy organs at risk when they become more sensitive.

Several factors can trigger dosemodulation. These include changes in tumor size or shape due to shrinkage or swelling, or changes in patient anatomy, such as weight loss or organ movement. Imaging technologies like cone-beam computed tomography (CBCT) or ultrasound are often used to acquire this real-time information.

The implementation of dosemodulation requires sophisticated treatment planning and delivery systems. It allows for a more personalized approach to radiation oncology, potentially leading to improved tumor control and reduced side effects compared to conventional, fixed-dose treatments. However, it also presents technical challenges and requires careful quality assurance to ensure accuracy and safety. This adaptive approach aims to enhance the precision of radiation delivery throughout the entire course of treatment.
