CT Simulation
A CT scan of the area of your body to be treated with radiation. The CT images acquired during your scan will be reconstructed and used to design the best and most precise treatment plan for you. Simulation is a critical preparation step before radiation treatment. During the simulation, the treatment setup will be simulated by positioning the patient on the flat couch immobilized by specially designed devices.
A 4D gating CT allows for the analysis of motion from breathing. It provides information on the true shape of the anatomical objects in motion, decreases distortion, and identifies the range of motion to help make radiotherapy planning assessment more precise.
3D Conformal Radiation Therapy (3D CRT)
Three-dimensional conformal radiation therapy (3D CRT) is a common radiation therapy used to treat cancers in many parts of the body. 3D CRT utilizes radiation beams that are shaped to enter the patient from multiple angles in such a way that it spares as much healthy tissues as possible.
Intensity Modulated Radiation Therapy, (IMRT)
An intense, controlled dose of radiation that allows treatment in sensitive areas
Volumetric Modulated Arc therapy (VMAT)
VMAT is a form of IMRT where the dose of radiation is applied to the tumor by continuous 360º rotation of the treatment unit. The dose distribution is precise with the shaping and adaptation of the dose to the form of the tumor.
Image Guided Radiation Therapy, (IGRT)
A type of cancer treatment that uses imaging technologies that allow physicians to pinpoint certain tumors with greater accuracy just prior to each treatment.
Deep Inspiration Breath Hold
Deep inspiration breath hold (DIBH) is a radiation therapy technique where patients take a deep breath during treatment, and hold this breath while the radiation is delivered. By taking a deep breath in, your lungs fill with air and your heart will move away from your chest.
Stereotactic Radiosurgery (SRS)
Highly precise and intense treatment delivered to the brain, given over a short treatment course (1-5 treatments).
High Dose Rate Brachytherapy
Involves temporarily inserting the source of radiation directly at or very near the tumor site which limits the amount of healthy tissue exposed to radiation.
Low Dose Rate Brachytherapy
Including prostate seed implants, radioactive implants that treat prostate cancer in a single treatment procedure
