Medizinische Physik 3: Medizinische Laserphysik

Die medizinische Physik hat sich in den letzten Jahren zunehmend als interdisziplinäres Gebiet profiliert. Um dem Bedarf nach systematischer Weiterbildung von Physikern, die an medizinischen Einrichtungen tätig sind, gerecht zu werden, wurde das vorliegende Werk geschaffen. Es basiert auf dem Heidelberger Kurs für medizinische Physik.

Generators Generators are units that contain a radioactive “parent” nuclide with a relatively long half-life that decays to a short-lived “daughter” nuclide. The most commonly used generator is the technetium-99m (99m Tc) generator (Fig. 3-1), which consists of a heavily shielded column with molybdenum-99 (99 Mo; parent) bound to the alumina of the column. The 99m Tc (daughter) is “milked” (eluted) by drawing sterile saline through the column into the vacuum vial. The parent 99 Mo (small grey circles) remains on the column, but the daughter 99m Tc (white circles) is washed away in the saline.

4-5). Once all the gas is involved, no greater gas amplification is possible so that any further increases in voltage have little effect on the size of the pulse of current. This is the so-called Geiger region. A detector operating in this region is called a Geiger counter, or Geiger-Mueller counter, after its early developers. In the Geiger region, not only is the size of the current pulse almost independent of small changes in voltage, but the size of the pulse is also independent of the amount of ionization produced by the incoming radiation.

The new atom is radioactive and emits gamma photons or charged particles to produce the daughter nuclide (Fig. 3-8). A gamma photon is emitted following capture of a thermal neutron. This reaction is written as Target (neutron, gamma) daughter nuclide For example, 98 Mo(n, γ ) 99 Mo When the target atom captures a fast neutron a proton can be emitted. This capture reaction is sometimes referred to as transmutation and is symbolized as Target (neutron, proton) daughter nuclide For example, 32 S(n,p)32 P A list of common medical nuclides and their methods of production, modes of decay, and decay products is provided in Appendix A.
