The role of nonelastic reactions in absorbed dose distributions from therapeutic proton beams in different medium.
Many new techniques for delivering radiation therapy are being developed for the treatment of cancer. One of these, proton therapy, is becoming increasingly popular because of the precise way in which protons deliver dose to the tumor volume. In order to achieve this level of precision, extensive treatment planning needs to be carried out to determine the optimum beam energies, energy spread (w...
متن کاملComments on 'Converting absorbed dose to medium to absorbed dose to water for Monte Carlo based photon beam dose calculations'.
Current clinical experience in radiation therapy is based upon dose computations that report the absorbed dose to water, even though the patient is not made of water but of many different types of tissue. While Monte Carlo dose calculation algorithms have the potential for higher dose accuracy, they usually transport particles in and compute the absorbed dose to the patient media such as soft t...
متن کاملResponse functions for computing absorbed dose to skeletal tissues from neutron irradiation.
Spongiosa in the adult human skeleton consists of three tissues-active marrow (AM), inactive marrow (IM) and trabecularized mineral bone (TB). AM is considered to be the target tissue for assessment of both long-term leukemia risk and acute marrow toxicity following radiation exposure. The total shallow marrow (TM(50)), defined as all tissues lying within the first 50 µm of the bone surfaces, i...

study cultured stem cells from human embryos can proceed without violating the federal ban on embryo research in general. Since that decision, a great deal of excitement has arisen over the possibility that treatment of neurological disease may take a giant leap forward in the near future. The secrets to everything from preventing Alzheimer's Disease to reversing spinal cord damage may soon be ...
متن کاملThe absorbed dose to blood from blood-borne activity.
The radiation absorbed dose to blood and organs from activity in the blood is relevant for nuclear medicine dosimetry and for research in biodosimetry. The present study provides coefficients for the average absorbed dose rates to the blood from blood-borne activity for radionuclides frequently used in targeted radiotherapy and in PET diagnostics. The results were deduced from published data fo...
