Summary
Stereotactic radiosurgery (SRS) equipment has advanced, offering various systems for intracranial lesions. The choice of SRS technology depends on institutional needs and program strategy for optimal patient care.
Area of Science:
- Neurosurgery
- Radiation Oncology
- Medical Technology
Background:
- Stereotactic radiosurgery (SRS) is an established treatment for intracranial lesions.
- Advancements in SRS equipment are continuously evolving.
- Focus on brain neoplasms and other intracranial pathologies.
Purpose of the Study:
- To review and update information on stereotactic radiosurgery (SRS) equipment.
- To highlight advancements in technology for treating intracranial lesions and brain neoplasms.
Main Methods:
- Review of current SRS equipment and technologies.
- Discussion of dedicated and adapted radiosurgery systems.
- Integration of advanced radiation therapy techniques.
Main Results:
- Gamma Knife radiosurgery (GKRS) remains a gold standard, with newer versions like Leksell Gamma Knife Perfexion.
- Linear accelerator (LINAC)-based SRS, including robotic systems like CyberKnife, are increasingly utilized.
- TomoTherapy integrates intensity-modulated radiotherapy with CT imaging for advanced delivery.
Conclusions:
- SRS is a vital alternative treatment for diverse intracranial lesions.
- No single SRS system is universally superior; selection depends on specific program needs.
- The minimally invasive nature and growing acceptance of SRS promise continued innovation in neurosurgery and radiotherapy.

01:10Computed Tomography
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

01:14Brain Imaging
Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans), magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and Transcranial Magnetic Stimulation (TMS).

01:29Positron Emission Tomography
Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body being...

DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...
01:17Radiation: Applications
The average temperature of Earth is the subject of much current discussion. Earth is in radiative contact with both the Sun and dark space; it receives almost all its energy from the radiation of the Sun and reflects some of it into outer space. Dark space is very cold, about 3 K, so Earth radiates energy into it. For instance, heat transfer occurs from soil and grasses, the rate of which can be so rapid that frost can occur on clear summer evenings, even in warm latitudes.
