    Abstract: Portions of the radiation source are obscured so that the radiation only passes through the specific areas of the patient related to the regions-of-interest to the doctor. Scattered radiation received by detector pixels that are obscured by direct-line of sight radiation are used to estimate the scattered radiation in the un-obscured portion, which can be used to increase the accuracy of the image taken through the un-obscured portion.

    Abstract: A photodetector for detecting megavoltage (MV) radiation comprises a semiconductor conversion layer having a first surface and a second surface disposed opposite the first surface, a first electrode coupled to the first surface, a second electrode coupled to the second surface, and a low density substrate including a detector array coupled to the second electrode opposite the semiconductor conversion layer. The photodetector includes a sufficient thickness of a high density material to create a sufficient number of photoelectrons from incident MV radiation, so that the photoelectrons can be received by the conversion layer and converted to a sufficient of recharge carriers for detection by the detector array.

    Abstract: Techniques described herein generally relate to identifying, assessing, and managing cancer growth rates and potential metastasis. Some example methods may include constructing one or more quantitative metrics for the potential metastasis in a selected population of other patients, acquiring a first set of numeric biomarker data for the patient before having placed a biomarker in the patient, acquiring a second set of numeric biomarker data for the patient after having placed the biomarker in the patient, determining a set of biomarker surrogate values for microvessel density information based on a mean numeric biomarker difference derived from the first set of numeric biomarker data and the second set of numeric biomarker data, determining a set of biomarker surrogate values for microvessel density information based on a mean numeric biomarker difference derived from the first set of numeric biomarker data and the second set of numeric biomarker data, and predicting quantitative and objective risk for the cancer growth rates and potential metastasis and adjusting a treatment plan based on the biomarker surrogate values and at least one of the one or more quantitative metrics.
