Alternating electric fields (e.g., TTFields) may be applied to a subject's body using one or more electrode assemblies that includes a sheet of graphite, at least one layer of conductive material disposed on the front face of the sheet of graphite, and an electrode element positioned behind the sheet of graphite. The electrode element has a front face disposed in electrical contact with the rear face of the sheet of graphite. The sheet of graphite spreads both heat and current out in directions that are parallel to the front face of the sheet, which eliminates or at least minimizes hot spots on the electrode assembly. This in turn makes it possible to increase the current without exceeding a temperature safety threshold (e.g., 41° C.).

In a radiation therapy system, treatment X-rays are delivered to a target volume at the same time that imaging X-rays are also delivered to the target volume for generating image data of the target volume. That is, during an imaging interval in which imaging X-rays are delivered to the target volume, one or more pulses of treatment X-rays are also delivered to the target volume. In each pixel of an X-ray imaging device of the radiation therapy system, image signal is accumulated during portions of the imaging interval in which only imaging X-rays are delivered to the target volume and is prevented from accumulating in each pixel during the pulses of treatment X-rays.

The invention relates to a method for the production of milk with a high content of native vitamin D3, comprising the irradiation of one or more lactating animals in a roofed enclosure, having at least one luminaire with a lamp emitting UV-A and UV-B radiation, and the milking of animals. The method allows producing milk having a high content of native vitamin D. The method also leads to an improved milk yield per animal.

A structure includes a base comprising a first ramp and an opposing, second ramp. The structure further includes a shell frame having an inner surface configured to a shape of a body part and an outer convex surface, wherein the outer convex surface of the shell frame rides upon, and moves relative to, upper surfaces of the first ramp and the second ramp to enable a pitch of the shell frame to be adjusted relative to the base.

The present invention provides a device for rejuvenating a region of skin or mucosal tissue, comprising: a pulsed electromagnetic frequency generator; a plurality of electrodes in communication with the pulsed electromagnetic frequency generator and an RF tissue diathermy device. The electrodes apply the pulsed electromagnetic power and the RF tissue diathermy to the tissue, heating it such that one portion of the region of mucosal tissue is maintained at a predetermined temperature range T.sub.1 while another portion of the region of mucosal tissue is at least temporarily maintained at predetermined temperature range T.sub.2.

Systems and techniques may be used to estimate a patient state during a radiotherapy treatment. For example, a method may include generating a dictionary of expanded potential patient measurements and corresponding potential patient states using a preliminary motion model. The method may include training, using a machine learning technique, a correspondence motion model relating an input patient measurement to an output patient state using the dictionary. The method may include estimating, using a processor, the patient state corresponding to an input image using the correspondence motion model.

A pain relief device and method or system to aid in the resolution of pain in a body including at least one layer of PVDF film and at least one other layer for directional purposes, as well as a polarizing layer. The device can be packaged in various ways. Also described is a device that uses a combination of LED bulbs, polymer based materials and a near field accelerator to provide pain relief.

Methods and systems for modulating intraosseous nerves (e.g., nerves within bone) are provided. For example, the methods and systems described herein may be used to modulate (e.g., denervate, ablate) basivertebral nerves within vertebrae. The modulation of the basivertebral nerves may facilitate treatment of chronic back pain. The modulation may be performed by a neuromodulation device (e.g., an energy delivery device).
