A radiation detector includes a wiring board, a first image sensor, a second image sensor, a first fiber optic plate, a second fiber optic plate, and a scintillator layer. The first fiber optic plate can guide light between a first light entering region and a first light exiting region. The second fiber optic plate can guide light between a second light entering region and a second light exiting region. One side of the first light entering region and one side of the second light entering region are in contact with each other. The first light exiting region is positioned on a first light receiving region. The second light exiting region is positioned on a second light receiving region. One side surface of a first side surface and one side surface of a second side surface exhibit shapes along each other and in contact with each other.

A hand-held probe for measuring radiation or magnetic activity includes a probe having a handle having a longitudinal axis and a shaft portion adapted to be inserted or held above a radiation or magnetic emitting source implanted within a patient's body or tissue of interest, the shaft portion includes a radiation or magnetic activity sensor configured to detect and measure radiation emitted from the radiation emitting source or magnetic activity from a magnetic source; the radiation emitting source being an implanted seed or a radioisotope that is injected near a tumor site in the patient's body; the probe including a signal processing device for further processing the measured radiation or magnetic activity; and a communication medium to exchange data from the hand-held probe with an external data processor unit.

To produce 3D x-ray images, it is necessary to compensate for patient movement during the emission and detection of x-rays; this may be achieved by providing an x-ray sensor 20 comprising a digital x-ray detector 40, and an inertial sensor 50, 60 for providing positional information relating to changes in the relative position of the x-ray sensor during detection of x-rays.

An imaging capsule including, a radiation source, a collimator that provides a collimated beam from the radiation source, at least one detector configured to detect particles resulting from X-ray fluorescence and/or Compton backscattering in response to the collimated beam to reconstruct images of a user's gastrointestinal tract, wherein the imaging capsule is configured to identify an inflamed area, within the user's gastrointestinal tract, based on a count of the detected particles and initiate actions responsive to detecting the inflamed area.

Disclosed herein is an apparatus comprising an insertion tube; an image sensor inside the insertion tube; wherein the image sensor comprises an array of pixels; wherein the image sensor is configured to count numbers of particles of radiation incident on the pixels, within a period of time. Also disclosed herein is a method of using this apparatus.

Various embodiments of a device for in-vivo measurements radiopharmaceuticals used for diagnosis and monitoring of radiotherapy are presented. In some embodiments, the present disclosure relates to a device having a cannula that may include a measurement chamber, a radiation detector and a delivery lumen, wherein the device may be used to both deliver material to the patient (e.g., radiotracers used in radiopharmaceuticals) and measure levels and concentrations of radioactive material in, for example, the patient's blood both during and after administration of the radioactive material. In some embodiments, particles emitted by the radioactive material interact with a scintillation material, resulting in the release of light that may be transmitted, via the scintillation material and/or fiber optic material, to an optical detectors or processor for processing. In some embodiments, particle absorbing materials may be used to limit measurements to materials within the measurement chamber or other area of interest.

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.

The present invention is an improved barrier-contained radiological sensor holder. In particular, the present invention is directed to radiological sensor holder contained in a barrier sheath to reduce or prevent contamination. The radiological sensor holder preferably comprises a sensor holder at least partly contained within a barrier sheath having a closed end and an open end. The barrier sheath preferably comprises elastomer latex material and the sensor holder preferably comprises an exterior attachment and an interior container, where the exterior attachment presses a portion of the barrier sheath into a gapped attachment port on the interior container. The sensor holder may alternately include an expansion slit along the opposing face. The sensor holder can also have snap on articles for positioning the sensor for posterior, anterior and vertical image capture.

A dual-mode microwave applicator for treating tissue comprises a control unit, a rod-shaped element, a coaxial line, and a metal sleeve. The control unit controls the applicator in an application mode and a sensing mode. In the application mode microwave radiation is applied and during the sensing mode tumorous tissue is detected. The rod-shaped element comprises a tip. The coaxial line is formed in the rod-shaped element to relay microwaves to the tip for treatment of the tissue. The coaxial line comprises an inner conductor and an outer conductor. The outer conductor includes a slot of a slot length formed at a slot distance from the tip. The metal sleeve at a sleeve distance from the slot. The sleeve distance is about 0.55 mm, the slot length is about 1.75 mm, and the slot distance is about 7.7 mm.
