IMART+ is our advanced radiation technology program for IMRT (Intensity-Modulated Radiation Therapy).

Is an advanced mode of high-precision treatment that “paints” radiation doses onto the tumor with pinpoint precision while at the same time minimizing dose delivery to important nearby organs. This is achieved by modulating - or controlling – the intensity of the radiation beam in numerous small volumes. While IMRT has become widely available in recent years, we view IMRT as both an art and a science that requires much more than just a radiation machine and a computer.
In conjunction with IMRT is a highly sophisticated computational process where the optimal treatment plan for an individual patient is identified among a virtually infinite number of possible solutions. This is based on criteria specified by the radiation oncologist to maximize radiation dose delivery to the tumor and minimize exposure of healthy organs.
Is a prerequisite for accurate IMRT planning and delivery in body parts where there is breathing motion, i.e., the chest and upper abdomen. 4DCT simulation involves the acquisition of multiple CT scans during a patient’s breathing cycle, thereby logging the tumor position not only in space but also in time, so that the radiation beam will never miss the tumor.
Involves the use of imaging technology, such as X-rays or ultrasound, to accurately deliver the desired radiation doses to the tumor on a regular basis. The benefits of IMRT can only be realized with daily IGRT.
Is a form of IGRT where a CT scan is obtained right before the daily treatment, which allows the radiation therapy technicians and the treating radiation oncologist to fine tune a patient’s position for high-precision delivery of radiation doses.
