During the generation of a panoramic x-ray recording, the use of semi-transparent x-ray screens allows the patient's x-ray exposure to be reduced when partial x-ray images are created, in spite of relatively large overlapping areas between the partial x-ray images.

A non-contact angle measuring apparatus includes a matter-wave and energy (MWE) particle source and a detector. The MWE particle source is used for generating boson or fermion particles. The detector is used for detecting a plurality peaks or valleys of an interference pattern generated by 1) the boson or fermion particles corresponding to a slit, a bump, or a hole of a first plane and 2) matter waves' wavefront-split associated with the boson or fermion particles reflected by a second plane, wherein angular locations of the plurality peaks or valleys of the interference pattern, a first distance between a joint region of the first plane and the second plane, and a second distance between the detector and the slit are used for deciding an angle between the first plane and the second plane.

An apparatus for detecting a locating medium in tissue includes a probe, and a console. The probe includes a handle and a detector disposed on a distal end of the probe. The console is in communication and includes a display. The display has a first graphical representation and a second graphical representation. The first graphical representation is configured to depict a count real-time count based on a signal from the detector. The second graphical representation is configured to depict a target count.

A system and corresponding method for detecting one or more high-atomic-number elements in a patient includes a Bremsstrahlung x-ray source that produces x-rays in an energy spectrum including an energy of at least 160 kiloelectron-volts (keV), a filter configured to absorb the x-rays in a region of the energy spectrum, and a collimator configured to receive the x-rays and output a collimated x-ray beam to be incident on a patient. The system and method can also include one or more collimated, energy-resolving x-ray detectors to detect fluorescent radiation emitted from the one or more high-atomic-number elements in the patient in response to the collimated x-ray beam incident on the patient. An alternative x-ray source can include a radioactive isotope. Scanning of the x-ray beam may also be performed. Embodiments enable practical clinical, in vivo measurements of lead in bone.

The invention comprises a patient specific tray insert removably inserted into a tray frame to form a beam control tray assembly, which is removably inserted into a slot of a tray receiver assembly proximate a gantry nozzle of a charged particle cancer treatment system. Optionally, multiple tray inserts, each used to control a different beam state parameter, are inserted into corresponding slots of the tray receiver assembly where the multiple inserts are used to control beam intensity, shape, focus, and/or energy. The beam control tray assembling includes an identifier, such as an electromechanical identifier, of the particular insert type, which is communicated to a main controller, such as via the tray receiver assembly along with slot position and/or patient information.

According to one embodiment, a medical information processing apparatus includes processing circuitry. The processing circuitry is configured to receive data acquired by scan for an object, and output a reconstructed image data based on the data and a trained model that accepts the data as input data and outputs the reconstructed image data corresponding to the data. The trained model is trained by learning using raw data generated based on a numerical phantom and the numerical phantom.

The invention comprises a system for determining the state of a charged particle beam, such as beam position, intensity, and/or energy. For example, the charged particle beam state is determined at or about a patient undergoing charged particle cancer therapy using one or more film layers designed to emit photons upon passage of a charged particle beam, which yields information on position and/or intensity of the charged particle beam. The emitted photons are used to calculate position of the treatment beam in imaging and/or during tumor treatment. Optionally and preferably, updating a tomography map uses the same hardware with the same alignment used for cancer therapy at proximately the same time.

The invention comprises an apparatus and method of use thereof for determining a charged particle beam state after passage through a final beam modification insert and prior to entering a patient, such as in cancer treatment or tomographic imaging. The insert comprises a range shifter, a known energy absorber, a ridge filter, a focal length altering insert, an aperture defining element, a compensator, and/or a patient specific beam modifier. The monitoring element comprises one or more sheets, configured to emit photons upon passage therethrough of the charged particle beam, where the emitted photons are detected, tested, such as against a predetermined cancer treatment plan, and/or used to aid in three dimensional tomographic image generation.
