Introduction

Introduction

Advanced Radiotherapy Eqipments uses the ionizing radiation (high-energy radiation that displaces electrons from atoms and molecules) to destroy cancer cells

These technologies have improved the quality of radiation treatment, by enabling precise positioning of the patients, and targeting of tumours minimising doses to normal healthy tissues.

What is SBRT and it's Purpose?

What is Streotactic Body Rdtation Therapy

Stereotactic Body Radiation Therapy (SBRT) is a radiation therapy approach which delivers high dose radiation to a target within the body, in either a single or up to five treatment sessions. It is similar to central nervous system stereotactic radiosurgery, except that it deals with tumors outside the central nervous system (CNS).

How does it works?

How does it work?

  • Specifically designed coordinate- system
  • multiple, highly precise radiation beams
  • use of better quality imaging e.g. CT scans, PET, MRT
  • this type of treatment requires millimeter precision
  • Immobilisation devices are equipment to ensure the patient does not move during the entire radiation therapy. These include head and neck ‘masks’ and body moulds.

What is CyberKnife system?

What is CyberKnife System?

  • The CyberKnife System is a non-invasive treatment for cancerous and non-cancerous tumors
  • It is used to treat conditions throughout the body, including the prostate, lung, brain, spine, head and neck, liver, pancreas and kidney.
  • CyberKnife treatments are typically performed in 1 to 5 sessions.
  • The CyberKnife System has more than two decades of clinical proof and has helped thousands of cancer patients
  • The CyberKnife System is the first and only fully robotic radiotherapy device

Working

Working

  • The CyberKnife System is the only radiation delivery system that features a linear accelerator (linac) directly mounted on a robot to deliver the high-energy x-rays or photons used in radiation therapy.
  • The robot moves and bends around the patient, to deliver radiation doses from potentially thousands of unique beam angles.
  • This robotic delivery and real-time image guidance have set the standard for delivery precision.

What iS IMRT?

What is IMRT?

Intensity-modulated radiation therapy (IMRT) is an advanced mode of high-precision radiotherapy that uses computer-controlled linear accelerators to deliver precise radiation doses to a malignant tumor or specific areas within the tumor. IMRT allows for the radiation dose to conform more precisely to the three-dimensional (3-D) shape of the tumor by modulating—or controlling—the intensity of the radiation beam in multiple small volumes. IMRT also allows higher radiation doses to be focused on the tumor while minimizing the dose to surrounding normal critical structures.

Procedure

Equipments and Procedure

  • A medical linear accelerator (LINAC) generates the photons, or x-rays, used in IMRT.
  • The intensity of each beam's radiation dose is dynamically varied according to treatment plan.
  • The time in the treatment room depends on the specific plan, but usually is between 15 minutes and one hour.

In the beginning of the treatment session, the radiation therapist positions the patient on the treatment table, guided by the marks on the skin (tattoos) defining the treatment area. If molded devices were made, they will be used to help the patient maintain the proper position. The patient may be repositioned during the procedure. Imaging systems on the treatment machine such as x-ray or CT may be used to check positioning and marker location.
