ProBeam (system of proton therapy)

The system of proton therapy ProBeam from Varian Medical Systems company provides beam cancer therapy. By 2018 proton therapy is considered the most exact and least toxic method of radiation therapy.

Design feature of the ProBeam system is use of an isochronous cyclotron with the supercarrying-out electromagnets (the so-called supercarrying-out cyclotron). Its power opportunities allow to perform delivery of doses of radiation to the tumors lying at a depth of 4-30 cm, providing broad power range for treatment - without use of switches of range of action.

For ProBeam it is necessary much less the place, than for the multiroom centers: a system can be unrolled on the square approximately in the amount of the tennis court or about 20 parking spaces.

2020: Varian will use ProBeam at tests of FLASH therapy for cancer therapy

In the middle of October, 2020 the Varian Medical Systems company began the first-ever clinical trials of devices for FLASH therapy. Developers hope that favorable results of tests will allow to use everywhere new approach to radiation therapy using an ultrahigh dose of radiation lasting less than a second which allows to destroy cancer cells with the minimum ghost effects.

2018: Release of the version of ProBeam 360 °

On October 20, 2018 the Varian Medical Systems company released the compact system of proton therapy of ProBeam 360 °. A new system takes 30% less places, than the previous model and by that it cuts down expenses on its installation for a quarter, saving and expanding clinical opportunities. A new system is equipped gentr, rotating by 360 degrees, by the most powerful of available for October, 2018 the accelerator of particles, the system of an iterative conic computer tomography and technology of high-quality scanning by a narrowly targeted beam. A system can be also used for performing therapy of new generation, for example, of high-speed radiation therapy ("flash" are therapies).

ProBeam 360 rotating gentr ° accelerates process of intensive proton therapy, minimizing movement and repeated impact on the patient, and allows to receive the high-quality image at a conic beam tomography almost at any angle of shooting. The RapidScan technology used in ProBeam 360 ° simplifies process of scanning and therapy thanks to the program of control of respiratory movements that in turn increases a share of patients for whom it is necessary performing stereotaksichesky radiation therapy of lungs, at which breath of the patient can displace a tumor. The powerful accelerator of particles provides a high dose of radiation therapy, reducing time of treatment and improving its quality.

Varian released the system of proton therapy of ProBeam 360 °. 30% more compact than the predecessor

Besides, the technology of scanning by a narrowly targeted beam with high resolution capability gives to clinical physicians the chance to process exclusively malignant tumor, minimizing impact on surrounding healthy fabrics. In combination with technology of an iterative conic computer tomography the ProBeam 360 system ° provides highly effective and exact radiation therapy with the minimum side effect.^[1]

Use in Russia

In March, 2018 it became known that the Medical  institute  of  Berezina  of Sergey  (MIBS)  carried out the first procedure of proton therapy to the child, using the ProBeam system from Varian Medical Systems company. According to forecasts of organization, thanks to ProBeam every year in the center it will be possible to cure about 1000 cancer patients.

Scanning by a pencil bunch (pencil beam scanning, PBS) or an ostronapravlenny beam — the advanced method in use of protons for cancer therapy applied so far in the few proton centers of the world. The command of the Center of proton therapy of MIBS mastered PBS technology.

System of proton therapy ProBeam

In March, 2018 at a meeting with workers of health sector in St. Petersburg the Russian President Vladimir Putin said that the oncology becomes one of priorities in development of health care, and the state will allocate additional resources for treatment of oncological diseases using radiological methods.^[2]

Use in the world

In the fourth quarter 2017 Varian Medical Systems received orders for installation of a system of proton therapy of ProBeam at the University of Alabama (the University of Alabama) in Birmingham and in the oncological center of the University of Miami (University of Miami).
