  • Publication number: 20220346659
    Abstract: Radiomic analysis of multiparametric magnetic resonance imaging (“MRI”) and magnetic resonance fingerprinting (“MRF”) data enhances delineation and mapping of tumor regions. Radiomic features are extracted from MRI and MRF tumor images. Distinct tumor regions, including but not limited to necrotic core, enhancing tumor, and peritumoral white matter, are segmented and mapped. Whole tumor as well as tumor region characteristics are evaluated. Tumors can also be differentiated and classified by pathology, grading, staging, and so on.

  • Patent number: 11231506
    Abstract: The present disclosure teaches a UV dosimeter comprising a UV-sensitive layer and a barrier that protects the UV-sensitive layer. The barrier is permeable to oxygen but impermeable to water and, thus, protects the UV-sensitive layer from water while allowing exposure of the UV-sensitive layer to oxygen. The UV-sensitive layer is accessible to both UV radiation and visible light. The UV-sensitive layer comprises a mixture of a semiconductor material, a UV-oxidizable dye, a sacrificial electron donor, and a matrix material. The semiconductor material has a band gap that corresponds to photon energy of the UV radiation. The dye has both an oxidation state and a reduction state. The oxidation state of the dye is visibly distinguishable from the reduction state of the dye. The sacrificial electron donor oxidizes when exposed to UV radiation. The matrix provides structural integrity to the mixture.
