How does a linear particle accelerator work?

radiotherapy tolerance tests

SHORT VERSION

A linear particle accelerator is a radiation therapy machine that creates a radiation beam specifically directed to the tumor to kill cancer cells. This machine is composed of different parts: an electron gun that produces the electron beam an accelerator section to bring kinetic energy to the beam a target against which the electron beam strikes, causing reactions that will create a photon beam (this part is removed when using an electron beam) accessories (such as collimators) that are located in the machine head and allow modulating (sculpting) the beam shape and to direct it towards the area to be treated. Once directed towards the patient, the radiation beam will reach the tumor tissue/cells.

FIRST TESTS TO PREDICT A PATIENT’S RADIOSENSITIVITY

NovaGray develops and commercializes the first radiotherapy tolerance tests for patients treated for breast or prostate cancer.

Performed before the start of radiotherapy with a simple blood draw, the tests assess the patients’ individual radiosensitivity and determine their risk of developing late complications after radiotherapy.

WHY DO A RADIOSENSITIVITY TEST?

Knowing a patient’s individual radiosensitivity is important information that can help:

  • Reassure the patient in preparation for radiotherapy
  • Guide physicians in choosing the most appropriate treatment plan
  • Adapt patient follow-up after radiotherapy

Team NovaGray

NovaGray develops radiotherapy tolerance tests for breast and prostate cancer patients. NovaGray's mission is to help personalize cancer treatment by assessing each patient's individual sensitivity before starting radiotherapy. NovaGray technology has been validated by multi-center prospective clinical trials. NovaGray tests are recommended by the French Society of Radiation Oncology (SFRO).
