Stereotactic radiation can be used either as single-fraction radiosurgery (SRS) or by dividing the radiation dose into several sessions, which is called fractionated stereotactic radiotherapy (FRS). Both forms of radiation (SRS and FSR) affect the human body in the same way, damaging the DNA inside tumor cells. The cells can no longer divide and eventually die, a process called necrosis. Both methods are performed practically on an outpatient basis and do not require general anesthesia or a long hospital stay.
Over the past few decades, as technology has improved, "delivery to the point of application&Stereotactic radiation, an increasing number of patients are choosing stereotactic radiosurgery as their primary treatment, for example, acoustic neurinoma. There are several different devices available in practical use that are used to treat acoustic neurinomas using technologies that differ in the source of radiation and the method of its delivery.
For example, Gamma Knife machines receive their radiation from a fixed set of Cobalt-60 sources. These machines are usually used to deliver SRS in a single session, although the latest platform (Leksell Gamma Knife® Icon) allows fractional delivery (FRS).
Linear accelerator (LINAC) machines operate by accelerating electrons to produce high-energy X-rays. The beam of X-rays (photons) then forms a path to the tumor as it exits the machine, using a series of collimators and rotating the patient or machine. LINAC machines are manufactured by various manufacturers with common trade names, including CyberKnife, Trilogy, Novalis Tx, and TruBeam, among others, with each machine available for both single-session (SRS) and multi-session (FSR) therapy.
Proton beam machines use a particle accelerator to generate radiation energy in the form of protons, which can be delivered as SRS or FSR.
Despite all their differences, similar results in terms of effective treatment of acoustic neuritis and avoidance of side effects were recorded for each of the stereotactic radiation modulating machines.
Staff for comprehensive maintenance and work at similar facilities should not include a neurosurgeon or neuropathologist and a radiation oncologist, except for support technical staff.
A number of factors are usually considered before determining whether radiation therapy is appropriate, including the degree of growth of acoustic neurinoma and the rate at which it grows, the patient's age and general health, as well as the patient's symptoms, including the degree of hearing loss, vestibular problems, and severity of dizziness. As a rule, acoustic neurinomas larger than 2.5 - 3 cm are not considered ideal candidates for radiation therapy, since these tumors often compress the surrounding brain stem, and the likelihood of side effects from radiation increases. http://www.1xbet.io/ gaming platform is designed for fans of virtual gambling who value variety and convenience.
