Radiosurgery is an exceptional avant-garde technology. It offers the possibility of treating certain brain disorders without the need for invasive surgery. It uses high-precision mini-beams of X-rays to precisely target tumors, vascular malformations and neurological disorders.  <\/p>\n\n\n\n

What is radiosurgery?<\/h2>\n\n\n\n

Radiosurgery is a sophisticated stereotactic radiotherapy<\/strong> technique that uses precisely directed beams of radiation to eliminate a specific tumor, vascular malformation or treat certain neurological disorders, while preserving surrounding healthy tissue.<\/p>\n\n\n\n

<\/div>\n\n\n\n

In practice, radiosurgery works on the principle of a magnifying glass that focuses sunlight. <\/p>\n\n\n\n

<\/div>\n\n\n\n

Taken individually, each beam is of low intensity and harmless to the tissue it passes through. But when they meet exactly on the target area, their combined force is powerful enough to eliminate abnormal cells. <\/p>\n\n\n\n

<\/div>\n\n\n\n

This technique is based on the use of a highly precise three-dimensional tracking system<\/strong> (called stereotaxis), to map the area to be treated and guide the rays with surgical precision. <\/p>\n\n\n\n

<\/div>\n\n\n\n

In this setting, sessions are quick, painless and require neither incision nor hospitalization<\/strong>.<\/p>\n\n\n\n

Where does radiosurgery come from?<\/strong><\/h3>\n\n\n\n
<\/div>\n\n\n\n

Radiosurgery was invented in 1951 by Swedish neurosurgeon Karl Leksell. <\/p>\n\n\n\n

<\/div>\n\n\n\n

After several trials with proton beams, he developed the Gamma Knife<\/strong>, a device that uses cobalt-60 sources to treat brain lesions with millimetric precision<\/strong>.<\/p>\n\n\n\n

<\/div>\n\n\n\n

In the 1980s, conventional linear gas pedals for radiotherapy were adapted to use this technique with X-ray beams.<\/p>\n\n\n\n

<\/div>\n\n\n\n

In the 1990s, the arrival of dedicated linear gas pedals <\/strong>, i.e. those designed exclusively for this activity, <\/strong> further expanded treatment possibilities: <\/p>\n\n\n\n
