Abstract: An image of an object is synergistically reconstructed using two or multiple imaging modalities. A first reconstructed image, showing structural information of the object is produced using a first imaging modality. The first reconstructed image is segmented, and known optical properties of the object are then mapped to the first reconstructed image. Optical signal emissions from the object are detected and registered with the first reconstructed image. A second reconstructed image volume is then produced using a second imaging modality, based on the mapped optical properties after registration between the first image and the data from the second modality. The second reconstructed image depicts some optical property, such as a bioluminescent source distribution, or optical properties, such as, attenuation and scattering properties, of the object.

Abstract: 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.
