Physics & the Detection of Medical X-Rays
X-Ray Production
Students can study the detection of x-rays without knowing how they are produced. However, knowledge of the production processes will help them understand better the overall process and the way in which x-rays obtain their high energies. Prior to studying the material covered in the Web pages listed below, students should have a knowledge of
-
Conservation of energy
-
Light as a form of energy
Messprinzip Produktion
The diagram at the top of the page provides labels in both English and German of the important components of an x-ray tube. The rest of the page is in German.
A set of 35 PowerPoint slides that review the basic ideas of x-ray production. The approach is qualitative with very few numbers and no equations. This set contains several links to the Web pages in the next link.
Production of X-rays
Several short lessons on the production of x-rays.
These lessons focus on the atomic processes and are primarily visual.
Much of it can be viewed without a knowledge of English. This
sequence is part of a
larger set of materials that look at all aspects of the physics of medical
imaging.
This animated sequence is part of the same course as the ones in the link above. It provides some details on the process by which x-rays are produced in a modern x-ray tube but does not present the atomic level details. These animation can be viewed with a knowledge of English.
Part of a set of materials for teaching students in approximately year nine of school about modern physics. This site contains many animation, including one about the basic process of producing x-rays.
Radiation
This site is aimed at dental technicians. It contains
basic information on x-rays and their production. Then, it continues with
dosage and safety issues.
A German translation of Physics 2000, this material is part of a set of materials for teaching students in approximately year nine of school about modern physics. This site contains many animation, including one about the basic process of producing x-rays.
HyperPysics X-Ray Tube
Basic description of the x-ray tube with links to the types
of x-rays.
Zwei Arten von Röntgenstrahlung
These short screens provide an introduction to
characteristic rays and brehmstrahlung. An analogy with skiing is
presented for brehmstrahlung. These screens are part of a
larger set
on x-rays.
Virtual Physics in Radiology
Tutorials
The first three links give very short descriptions of x-ray
production. Most useful is
the third link
which is a diagram of a modern x-ray tube. The animations load rather
slowly and have limited value.
Bremstrahlung &
K X-Ray
Production
Two separate links to two animations. Each is rather
short and simple. Shown together they can help the students understand
the difference between the two types of x-ray production. Because no
words are on the screen, the presentation does not depend on language.
Electromagnetic Spectrum & X-Rays
A textual presentation of the propeties and production of
x-rays. These pages include appropriate equations.
Röntgestrahlung
This text-style description of x-ray production contains
several graphics and some equations. PDF.
