This invention relates to single session image guided all field simultaneous radiation therapy combined with hyperthermia. Hyperthermia renders the radiation resistant cells as more radiation sensitive cells. The high and super-high dose rate radiation greatly improves the RBE of the photon radiation. It also minimizes photon radiation therapy's OER and cell cycle dependent tumor cell kill by minimizing the repair capacity of cell after photon radiation. Single session hyperthermia and radiation therapy overcomes the thermotolerance-associated inefficiency of hyperthermia treatment as it is when hyperthermia is combined with fractionated, lower dose rate radiation. The synergetic effects of sublethal damage repair inhibiting single session hyperthermia-combined with high dose and dose rate single session radiation therapy, and combined chemotherapy brings the photon radiation therapy's tumor cure and control capabilities closer to high LET radiation therapy.

A method of cellular evaluation based on the electronic nature of cells is reveled though cellular reproductions use of a magnetic force. The dynamic process of nuclear response is shown to be electronic in nature relative to DNA mediating electrons hydrogen bonding in bases pairing of DNA though out the a cell cycle and finally during metaphase one see the magnetic component of interaction. The electrostatic understanding of magnetic force is not well defined in physics in the process of electrodynamic. Cells use electrodynamic interaction within the cell are being studied as the basis and using the cell to measure and define electrodynamic interaction with the system that is biological a call. Specifically DNA thought the electronic interaction interactions. It appears infrared spectrum holds promises to help in revel these mechanisms. The promise of understanding or merely evaluation of electrodynamic interaction holds great promise to science with the greatest medical implication to understand genomic responses in cells. Understanding how the DNA interacts within a cell dynamic transition are known to take place and these are regulated thought electrodynamic interaction.
