Abstract: In accordance with embodiments of the invention, at least the potential presence of Special Nuclear Material (“SNM”) is determined by the detection of prompt neutrons, prompt gamma rays, delayed neutrons, and/or delayed gamma rays from photofission, via time-of-flight (“TOF”) spectroscopic methods. Methods and systems are disclosed.

Abstract: A facility for facilitating custom radiation treatment planning is described. During a distinguished radiation treatment session for a patient, the facility collects data indicating positioning of a predefined treatment site of the patient relative to a target treatment location throughout the distinguished radiation treatment session. The facility associates the collected positioning data with data describing one or more other aspects of the distinguished radiation treatment session. The facility provides the associated data to a treatment planning facility to determine a treatment plan for future radiation treatment sessions for the patient.

Abstract: Systems and methods for real-time target validation during radiation treatment therapy based on real-time target displacement and radiation dosimetry measurements.

Abstract: Several related inventions for estimating scattered radiation in radiographic projections are disclosed. Several of the inventions use scatter kernels of various forms, including symmetric and asymmetric forms. The inventions may be used alone or in various combinations with one another. The resulting estimates of scattered radiation may be used to correct the projections, which can improve the results of tomographic reconstructions. Still other inventions of the present application generate estimates of scattered radiation from shaded or partially shaded regions of a radiographic projection, which may be used to correct the projections or used to adjust the estimates of scattered radiation generated according to inventions of the present application that employ kernels.

Abstract: The invention relates to methods of obtaining an expanded population of mammalian ex vivo cells and/or for treating a mammalian subject by (a) administering to a subject an effective amount of an agent that confers a growth disadvantage to at least a subset of endogenous cells at the site of engraftment; (b) administering to the subject an effective amount of a mitogenic stimulus for the ex vivo cells; and (c) administering the ex vivo cells to the subject, wherein the ex vivo cells engraft at the site and proliferate to a greater extent than the subset of endogenous cells, to repopulate at least a portion of the engraftment site with the ex vivo cells. The repopulated cells can be harvested for further use or be left at the engraftment site of a subject to be treated. The invention also provides methods of treating brain injury in a subject by engrafting ex vivo cells at the site of injury.

Abstract: Techniques described herein generally relate to identifying, assessing, and managing cancer diseases.

Abstract: Liquid metal containment in an x-ray tube. In one example embodiment, an x-ray tube anode assembly includes a shaft terminated by a head and an anode connected to an anode hub. The anode hub is at least partially surrounding the head of the shaft. The anode hub is configured to contain a volume of a liquid metal and to rotate around the stationary shaft. The anode hub may also define a catch space within the anode hub that is configured to catch the liquid metal in order to contain the liquid metal within the hub while in a non-rotating state and regardless of the orientation of the x-ray tube anode assembly.
