VMAT Therapy, or Volumetric Modulated Arc Therapy, is an advanced form of radiation therapy that offers a highly efficient and precise method for delivering radiation treatment. It is an evolution of Intensity-Modulated Radiation Therapy (IMRT) that combines intensity modulation with rotational delivery. Instead of delivering radiation from a fixed number of angles, a VMAT system delivers radiation continuously as the treatment machine (linear accelerator) rotates 360 degrees around the patient. As the machine rotates, multiple parameters are dynamically adjusted: the speed of the rotation, the shape of the radiation beam (controlled by a multi-leaf collimator or MLC), and the dose rate of the radiation. This dynamic, continuous delivery allows VMAT to create a highly conformal dose distribution that precisely targets the tumor while sparing surrounding healthy tissues, often more effectively than traditional IMRT. A key advantage of VMAT is its speed. Because the radiation is delivered in continuous arcs rather than discrete beams, the entire treatment session can be completed in just a few minutes, significantly reducing the amount of time a patient spends on the treatment couch. This not only improves patient comfort but also minimizes the potential for patient movement during treatment, which further enhances precision. VMAT is particularly beneficial for treating complex tumors located near critical organs, such as those in the head and neck, prostate, lung, and spine. By combining high precision with rapid delivery, VMAT enhances both the effectiveness and efficiency of radiation therapy, leading to potentially better tumor control, fewer side effects, and an improved overall patient experience.
