This invention relates the use of cortisol blockers (glucocorticoid receptor [GR] antagonists) for the treating or preventing treatment resistant prostate cancer, treating or preventing neoplasia, and treating or preventing infection related to acute or chronic injury or disease.

A system and method for planning surgical procedure including importing CT image data of a patient; generating a 3D reconstruction from the CT image data; presenting a slice of the 3D reconstruction; selecting a target anatomical feature from the slice of the 3D reconstruction; setting a treatment zone including presenting at least one slice of the 3D reconstruction including the target anatomical feature, and presenting a treatment zone marker defining a location and a size of the treatment zone on the presented at least one slice of the 3D reconstruction; setting an access route to the treatment zone; and presenting a three-dimensional model including the treatment zone and the access route.

A brachytherapy afterloader device, comprises at least one transmit wire that is suitable for being inserted and driven in an advance or retract motion in an external first delivery channel and for delivering drive energy to a test field source, which is arranged at a distal end region of the transmit wire, for generating a magnetic test field; at least one receive wire that is suitable for being inserted and driven in an advance or retract motion in an external second delivery channel for a measurement of the magnetic test field, the receive wire having a transducer that is configured to detect magnetic-field changes in the magnetic test field; and a wire driving unit which is configured to controllably advance or retract the transmit wire and the receive wire in response to a corresponding test drive control signal.

A neutron activator for neutron activation of a material, the neutron activator being configured to produce neutrons from an interaction with a proton beam (7), the neutron activator comprising: a neutron source comprising a metallic target (1), and a Beryllium first reflector-moderator (4) peripheral to the neutron source and comprising a neutron activation area (10) configured to accommodate the neutron source and the material to be activated, the neutron activation area (10) of the first reflector-moderator (4) comprising a bore configured to accommodate the neutron source. FIG. 1

Apparatuses and methods described herein relate to treating cancerous tumors using radiation therapy and chemotherapy. In some embodiments, a method of treatment includes administering radiation therapy targeting a tumor, isolating a segment of a vessel proximate to the tumor, and administering a dose of a chemotherapeutic agent to the segment of the vessel. The method can further include waiting a period of time after administering the radiation therapy before administering the dose of the chemotherapeutic agent. In some embodiments, a catheter device including first and second occluding elements can be used to isolate the segment of the vessel.

Misconnected applicators are eliminated in a brachytherapy treatment system by associating the output channels of an afterloader with the channel numbers after the applicators have been coupled to the output channels. In addition, the brachytherapy treatment system ensures the delivery of a proper dose by identifying the exact locations of the distal ends of the applicators right before the radiation treatment is to begin, and determining the final dose based on the exact locations.

An x-ray treatment system includes an electron beam generator configured to generate an electron beam and an x-ray treatment head comprising an array of pixel source cells including side walls defining an x-ray transmissive interior. The side walls include an x-ray absorptive material. A target element is positioned to, when impacted by the electron beam, generate x-ray photon radiation within the x-ray transmissive pixel source cell interior. An electron beam control system includes a controller configured to control responsive to a treatment plan at least one of the direction and intensity of the electron beam to a particular one of the pixel source cells, and then responsive to the treatment plan to control at least one of the direction and intensity of the electron beam to at least one additional pixel source cell. A method of treating a patient with x-ray photon radiation is also disclosed.
