A medical doctor specialized in the use of radiation for the treatment of cancer, responsible for determining and prescribing the appropriate course of treatment.

A type of equipment that uses high-energy x-rays to treat cancer by delivering radiation beams to the tumor site, sparing normal tissue.

A method of delivering radiation from outside the body, using a linear accelerator to target tumors with high-energy beams.

Radiation therapy that uses imaging techniques such as CT, MRI, or X-rays during treatment to improve the precision and accuracy of treatment delivery.

A highly precise and intense form of radiation therapy that targets tumors in the body with high doses of radiation, while minimizing the dose to surrounding healthy tissues.

Contours that represent the distribution of a prescribed radiation dose within the treatment area, used to visualize and optimize the dose delivered to the tumor and surrounding tissues.

The amount of radiation energy absorbed by the body's tissues, measured in Grays (Gy), a fundamental aspect of planning and delivering radiation therapy.

A type of radiation therapy that uses protons rather than X-rays to treat cancer, allowing for more precise targeting of radiation doses with less impact on surrounding healthy tissue.

A serious illness that occurs when the entire body (or most of it) receives a high dose of radiation, usually over a short period of time, with symptoms depending on the exposure level.

A healthcare professional trained to administer the prescribed radiation treatment plans and operate radiation therapy equipment.

An advanced mode of high-precision radiation therapy that uses computer-controlled linear accelerators to deliver precise radiation doses to a malignant tumor or specific areas within the tumor.

The study of the interactions between ionizing radiation and living cells, critical for understanding the effects of radiation and improving radiation therapy treatments.

A treatment schedule in radiation therapy where the total dose of radiation is divided into smaller doses and treatments are given over a period of time.

A radiation treatment technique that shapes the radiation beams to closely approximate the shape of the tumor, thereby protecting nearby healthy tissues from radiation.

A professional who specializes in radiation treatment planning, calculating the dose distributions and machine settings to deliver the prescribed dose to the patient.

Refers to the susceptibility of cancer cells or normal tissues to the damaging effects of radiation, influencing how they respond to radiation therapy.

The four key mechanisms that contribute to the effectiveness of fractionated radiation therapy: Repair, Redistribution, Reoxygenation, and Repopulation.

A form of internal radiation therapy where radioactive material is placed directly into or near a tumor, providing a high dose with minimal exposure to surrounding healthy tissues.

A form of radiation therapy where the entire body is exposed to radiation, often used as part of the conditioning regimen for bone marrow or stem cell transplantation.

Refers to the side effects or complications that arise from radiation therapy, affecting both the cancer cells as well as potentially the normal tissues.

A radiation therapy technique that uses computerized imaging to create a 3D representation of the tumor, allowing for more accurate delivery of radiation to the cancerous area while sparing healthy tissue.

Prior to actual radiation treatment, a process where imaging studies are used to plan the precise location and dose of radiation that will be delivered.

The process of determining the radiation doses, methods, and techniques to be used for patient treatment, ensuring maximum tumor control with minimum harm to healthy tissue.

A measure that defines the three-dimensional space occupied by the tumor, which is essential for accurate dosage calculation and efficient radiation therapy planning.
