High resolution imaging system for digital dentistry
A structured dental x-ray detector implements an array of holes or channels filled with at least one of polycrystalline, amorphous, or nano-particle semiconductor x-ray or gamma ray converter materials. Readout electronics are configured for acquiring and analyzing signals from the detector; e.g., operating in a signal integration or photon detecting mode, or in a photon detecting mode with energy resolution. In dental application, a protective shell or frame can be provided to encapsulate the detector and readout electronics, with a wired or wireless communications link to a computer system configured for image data post-processing and storage of the readout signals, with an electronic display for the image data.
Multi-axis linear X-ray imaging system
Systems for large animal fluoroscopy having independently positionable X-ray emitter and X-ray detector arms on either side of the animal providing independent movement of the X-ray emitter and X-ray detector in multiple degrees of freedom.
Radiation imaging apparatus
A radiation imaging apparatus for supplying power in a non-contact manner includes a power reception coil disposed inside a housing together with a radiation detector and a detector contact conductive member, and configured to receive electric energy to be supplied to the radiation detector in a non-contact manner from a power feeding coil disposed outside the housing. The power reception coil is disposed in a second range including a first range in which the detector contact conductive member is formed in the normal direction (y direction) to an incident surface of the radiation detector where the radiation is incident so that an orientation of the center of a generated magnetic flux coincides with an in-plane direction (x direction) of the incident surface and coincides with a direction toward the radiation detector.
Time-resolved positron emission tomography encoder system for producing real-time, high resolution, three dimensional positron emission tomographic image without the necessity of performing image reconstruction
A Time-Resolved PET imaging system for producing real-time, high resolution, three-dimensional positron emission tomographic images without performing sinogram formation or image reconstruction. The third dimension is provided by measuring the T between the arrival times of gamma rays from a positron event being detected by two cooperating detectors. In order to determine the location of a positron event along the lines of response, the measurement includes a fast scintillator, constant fraction discriminator and the digital intervalometer. The arrival time of each photon in the annihilation process is recorded with respect to a clock frequency with picosecond resolution. This approach requires significantly fewer positron events, thus requiring fewer detectors, thereby resulting in a new, real-time TPET imaging system that is more efficient and more economical to produce than conventional PET systems.
STORAGE SLOTS FOR DIGITAL RADIOGRAPHIC DETECTORS
A mobile radiography apparatus includes a moveable transport frame and an adjustable support arm attached thereto to support an x-ray source. At least one digital detector storage slot in the transport frame is configured to receive and to controllably lower at least one portable radiographic detector into the slot at a controlled speed.
METHODS FOR X-RAY IMAGING OF A SUBJECT USING MULTIPLE-ENERGY DECOMPOSITION
Methods for quantitatively separating x-ray images of a subject having three or more component materials into component images using spectral imaging or multiple-energy imaging with 2D radiographic hardware implemented with scatter removal methods. The multiple-energy system may be extended by implementing DRC multiple energy decomposition and K-edge subtraction imaging methods.
Method and system for determining virtual outputs for a multi-energy x-ray imaging apparatus
The disclosure is directed at a method and apparatus for determining virtual outputs for a multi-energy x-ray apparatus. Based on the application that the x-ray apparatus is being used for, a general algorithm can be determined or selected. Inputs received from the x-ray apparatus can be substituted into the general algorithm to generate a virtual output algorithm for the x-ray apparatus. Virtual outputs can then be calculated using the virtual output algorithm.
SIMULTANEOUS MULTI-AXES IMAGING APPARATUS AND METHOD OF USE THEREOF
The invention comprises a method and apparatus for imaging a tumor with X-rays while, simultaneously or alternatingly, treating or imaging the tumor with positively charged particles. An X-ray imaging system, such as one or two sets of a cone beam X-ray source coupled to an X-ray detector, is rotatable about a first axis and a patient. The X-ray imaging system is positioned off axis a path of charged particles delivered through an exit port of a nozzle system from a synchrotron and does not block a path of the positively charged particles from the exit nozzle to the patient or an imaging path from the patient to a scintillation detector. Fiducial indicators are used to confirm an unobstructed path of the positively charged particles in a treatment room comprising many movable elements, such as the X-ray imaging system and a patient positioning system/couch.
IMAGING ASSISTED INTEGRATED TOMOGRAPHY - CANCER TREATMENT APPARATUS AND METHOD OF USE THEREOF
The invention relates to a method and apparatus for determining actual points along a positively charged particle beam path and/or vectors of the charged particle beam path, where the determined points and vectors aid tomographic construction of a three-dimensional image of a tumor and surrounding tissue. Further, the determined points and vectors of the positively charged particle beam are used in beam control safety, to modify a tumor treatment plan in real time, and/or in combination with co-gathered X-ray images to form a hybrid proton tomographyX-ray three-dimensional image. Preferably, common elements, such as an injector, accelerator, beam transport system, and/or patient positioning system are used for both tumor treatment and tumor imaging.
X-ray phosphor plate system
An x-ray phosphor plate system has an x-ray phosphor plate, which is configured to be exposed by x-ray light in a recording region, and which carries a shadowing marker, which is arranged in the recording region, on at least one side of the x-ray phosphor plate. The system also has a phosphor plate reader, which is configured to read the exposed x-ray phosphor plate in order to produce an x-ray recording. The shadowing marker has a shadowing effect in respect of x-ray light that is so small that the shadowing marker is only weakly identifiable, and/or only identifiable by way of image artefacts, and/or not identifiable when the x-ray recording is observed by a user. The phosphor plate reader instead has an identification algorithm, which is configured to identify whether or not the x-ray light was shadowed by the shadowing marker during the exposure.
