Summary
This chapter explores radiosurgery principles, focusing on conformity and selectivity. These crucial parameters, influenced by beam properties and delivery methods, are evaluated using dose-volume histograms and specific indices.
Area of Science:
- Medical Physics
- Radiation Oncology
Background:
- Radiosurgery involves precise radiation delivery.
- Understanding beam characteristics is fundamental.
Purpose of the Study:
- To detail the principles of conformity and selectivity in radiosurgery.
- To explain how physical beam properties and dose delivery impact these principles.
Main Methods:
- Discussion of ionizing radiation, beam production, and beam characteristics.
- Evaluation of conformity and selectivity using specific indices.
- Utilizing dose-volume histograms for analysis.
Main Results:
- Conformity and selectivity are key radiosurgery considerations.
- These parameters are affected by beam properties, delivery devices, and dose delivery methods.
- Target volume ratio and normal volume ratio are key evaluation indices.
Conclusions:
- Conformity and selectivity are essential for effective radiosurgery.
- Dose-volume histograms provide a basis for evaluating treatment precision.

Radiation: 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.

X-ray Imaging
German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with X-rays, and by 1900, X-ray was widely...
Positron 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...

Radiological Investigation III: Pulmonary Angiogram and PET Scan
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Isotopes and Radioisotopes
In the early 1900s, English chemist Frederick Soddy realized that an element could have atoms with different masses that were chemically indistinguishable. These different types are called isotopes — atoms of the same element that differ in mass. Isotopes differ in mass because they have different numbers of neutrons but are chemically identical because they have the same number of protons. Soddy was awarded the Nobel Prize in Chemistry in 1921 for this discovery.
