Had brain surgery and the application of radiation

In general, the tumors that develop in the brain are often good candidates for radiosurgery. It is a demand for radiation that passes through the skull and tissues and focuses on the mass targeted. The whole process was without bloodshed, skin and the skull are not required to be open to apply.

Radiosurgery is the common term for a type of radiotherapy which is usually done on the brain. Also known as stereotactic surgery, it usually involves radiation of high demand focused on the tumor, but saving the normal healthy tissue. The patient received radiation via linear accelerator or a source of radiation directed by a collection. There will be many small beams sent through the skull into the brain converge on the estate. Radiation therapy will work for both malignant and non-malignant tumors.

Types of radiation, the brain surgery
Radiation therapy has been a great boost for the field of brain surgery. This is a technique that is not only mean less invasive methods, but the patient cost and recovery time is greatly reduced.

Radiation particles come in many forms, such as the Elekta radiosurgery tool, the "Gamma Knife", using doses of gamma rays that bombard cancer growth. This uses beams of 201 small focused radiation to converge on cancer of the tumor. From the source of radiation from the isotope cobalt. The concept was created more than 30 years by a scientist named Lars Leksel, professor of neurosurgery at Karolinsk Institute in Stockholm, Sweden.

Another tool radiosurgery, with the trade name Cyberknife, killing tumor sends x-rays instead of Gamma. The beam is controlled by a robotic arm that uses data mapping software to target the mass. The software is used, called 6D, maps of the tumor in an unusual way. It will compensate for patient movement, as well as the use of X-ray data to determine the target area while offsetting the projected error. They claim to be making the accuracy of 0.5 mm error. As Gammaknife, it can be used for both benign and malignant. However, one of the main differences between the two is that Gammaknife is designed only for the cranial radiotherapy.

Expectations of patients with radiosurgery
Because radiation therapy is non-invasive, patients spend less time to recover, often without even needing to rest to recover at all. In the example of the use of the Gamma Knife procedure, the patient can resume normal activities the day after the procedure.

The Gamma Knife will take a long time to administer it. It may take 15 minutes to an hour to set up. There are some surgical procedures that are performed on the skull to adjust the headset when the beamlets are to be sent through.
