Radiation oncology is one of the three primary specialties, the other two being surgical and medical oncology, involved in the treatment of cancer. Radiation can be given as a curative modality, either alone or in combination with surgery and/or chemotherapy. It may also be used palliatively, to relieve symptoms in patients with incurable cancers.
Ionizing radiation (US, ionising radiation in the UK), including nuclear radiation, consists of subatomic particles or electromagnetic waves that have sufficient energy to ionize atoms or molecules by detaching electrons from them. [1] Some particles can travel up to 99% of the speed of light, and the electromagnetic waves are on the high ...
It has also been used with Stereotactic Body Radiation Therapy to assist with the initial set-up and detect intrafraction patient motion throughout treatment. For stereotactic surgery , SGRT allows a frameless system to be used to monitor the surface of the patient within an open-face immobilization mask.
Radioterapia de intensidade modulada, também conhecida como IMRT (Intensity Modulated Radiation Therapy), é uma técnica de radioterapia [19] conformal que tem por objectivo máximo preservar os órgãos de risco (tecidos adjacentes saudáveis), utilizando como táctica a modulação da intensidade da radiação que chega ao paciente, através da segmentação do feixe incidente em segmentos ...
Radionuclide therapy ( RNT, also known as unsealed source radiotherapy or molecular radiotherapy) uses radioactive substances called radiopharmaceuticals to treat medical conditions, particularly cancer. These are introduced into the body by various means ( injection or ingestion are the two most commonplace) and localise to specific locations ...
Intraoperative radiation therapy (IORT) is radiation therapy that is administered during surgery directly in the operating room (hence intraoperative ). Usually therapeutic levels of radiation are delivered to the tumor bed while the area is exposed during surgery. IORT is typically a component in the multidisciplinary treatment of locally ...
