What is RapidArc radiation therapy?

What is RapidArc radiation therapy?

RapidArc radiotherapy technology, produced by Varian Medical Systems, is an extremely fast and precise form of image-guided, intensity-modulated radiation therapy (IMRT). Image guidance improves tumor targeting. IMRT shapes the radiation dose so that it conforms closely to the 3D shape of your tumor.

Is IMRT the same as CyberKnife?

Intensity Modulated Radiation Therapy (IMRT). Stereotactic radiation therapy, also known as radiosurgery, GammaKnife, CyberKnife, or SBRT. Brachytherapy.

Is CyberKnife better than radiation?

Cyberknife Is More Accurate Than Traditional Radiation Therapy. Because it’s able to target diseased tissue, Cyberknife SBRT is much more accurate than traditional radiation therapy. SBRT can deliver radiation to a margin of one to five millimeters surrounding a tumor.

Is proton beam the same as CyberKnife?

Proton beam releases its energy only after travelling to its target, causing little damage to the tissues the beams pass through. Both photon beams and proton beams can be produced by a linear accelerator. CyberKnife is a specialized type of linear accelerator and is one way to perform stereotactic radiosurgery (SRS).

What is the difference between Vmat and RapidArc?

Even though target coverage was almost the same for RapidArc and IMRT, dose distribution homogeneity was better with the VMAT treatment. RapidArc showed a further improvement in healthy-tissue sparing and in OAR avoidance as compared with conventional IMRT without jeopardizing target coverage.

How effective is IMRT?

The meta-analysis demonstrates that IMRT provides improved long-term tumor overall survival and local control including LRFS and PFS. Additionally, IMRT yields a lower incidence of late toxicities induced by irradiation in NPC patients. Compared to 2D-RT, IMRT may be an effective treatment for patients with NPC.

Which is better IMRT or IGRT?

IGRT uses imaging with the therapy to increase the efficiency by improving the precision and accuracy of the treatment procedure. The IMRT therapy uses high-edged software and sophisticated hardware to vary the intensity and shape of radiation used for different parts of the treatment area.

Which is better VMAT or IMRT?

IMRT can improve dose conformity, but it requires longer delivery time (5–8). Compared with IMRT, volumetric modulated arc therapy (VMAT) has significantly improved the delivery efficiency and treatment time (7). IMRT has been previously compared with VMAT in various types of cancer (7,9–19).

Is rapid arc VMAT?

RapidArc™ Volumetric Arc Therapy (RapidArc™ VOLUMETRIC ARC THERAPY (VMAT)) is a modern treatment technique that allows for a faster treatment time and lower radiation dose to you using Volumetric Modulated Arc Therapy (RapidArc™ VOLUMETRIC ARC THERAPY (VMAT)).
