IGRTi

IGRTi is a term that has emerged in discussions related to advanced radiotherapy techniques. It refers to Image-Guided Radiotherapy integrated with imaging, specifically highlighting the use of sophisticated imaging technologies within the radiotherapy process. The 'i' in IGRTi emphasizes the crucial role of real-time or near real-time imaging to precisely locate and track the tumor and surrounding organs during treatment delivery.

This integration allows for adaptive radiotherapy, where treatment plans can be adjusted during the course of therapy based on changes observed in the patient's anatomy or the tumor's position. Technologies commonly employed within IGRTi frameworks include cone-beam computed tomography (CBCT), ultrasound, and magnetic resonance imaging (MRI), which are often mounted on or integrated with the linear accelerator. The primary goal of IGRTi is to maximize the radiation dose delivered to the tumor while minimizing exposure to healthy tissues, thereby improving treatment efficacy and reducing side effects. The continuous advancements in imaging and treatment delivery systems are driving the evolution and adoption of IGRTi protocols in clinical practice.
