Intensity-Modulated Radiation Therapy, or IMRT, delivers radiation using beams whose intensity can be adjusted across the treatment field. It helps shape the radiation dose around a tumour while reducing exposure to nearby healthy tissues. Treatment planning is based on detailed imaging and clinical assessment.
Image-Guided Radiation Therapy uses imaging before or during treatment to verify the position of the target area. It helps improve radiation delivery accuracy when anatomy or positioning may vary. The technique is commonly combined with advanced radiotherapy planning.
Volumetric Modulated Arc Therapy, or VMAT, delivers radiation while the treatment machine rotates around the patient. The beam shape and intensity are adjusted during delivery. It can provide highly conformal treatment for selected tumour sites.
Stereotactic Radiosurgery delivers precisely focused high-dose radiation to selected abnormalities, often within the brain. Despite its name, it does not involve a surgical incision. Treatment requires careful imaging, planning and immobilisation to protect surrounding structures.
Stereotactic Body Radiotherapy delivers highly focused radiation to selected tumours outside the brain, usually over a limited number of sessions. Detailed planning and motion management help maintain accuracy. Suitability depends on tumour size, location and surrounding organs.
Gated radiotherapy coordinates radiation delivery with particular phases of breathing or other monitored motion. It may be used when tumours move during respiration. The technique aims to improve targeting and reduce radiation exposure to surrounding healthy tissues.
Brachytherapy places radioactive sources inside or close to a treatment target. It allows high radiation doses to be delivered locally in selected cancers. The treatment schedule, source placement and safety procedures depend on the tumour and treatment plan.
Precision radiation planning uses medical imaging and specialised software to define tumour targets and nearby organs. The radiation dose is designed according to clinical goals and safety constraints. Planning may involve collaboration between radiation oncologists, physicists and radiation therapists.
External beam radiotherapy directs radiation toward a tumour from a machine positioned outside the body. It may be used alone or alongside surgery, chemotherapy or other cancer treatments. The appropriate technique and number of sessions depend on the diagnosis.
Radiation oncology care often requires coordination with medical oncologists, surgeons, radiologists and other specialists. Treatment decisions consider the cancer diagnosis, stage, previous treatment and individual goals. This approach helps integrate radiation therapy into the overall cancer care plan.
