Characteristics of Photon Beamss known as filtration or beam hardening. Beam quality is a measure of a photon beam’s penetration, and can be measured by thickness of a half-value layer in a specified metal, or by percentage depth dose in water.

Special Topics: Hyperthermia and Computersingly important. Also of importance is the understanding of the various 3 dimensional treatment planning systems including measurement based systems, Monte Carlo, pencil beam, convolution/superposition, and collapsed cone algorithms. It is also important to understand the concept of simulated annealing for the purpose of IMRT planning.

Hierarchical Spline Approximations, decay (release a helium nucleus). If a nucleus is very light and proton heavy, it will undergo either positron emission or electron capture. If a nucleus is neutron heavy it will likely undergo beta-minus decay. Whenever any of these decay schemes result in an excited nucleus, the nucleus may resum
