Radiotherapy apparatus with on-board stereotactic imaging system

The present invention provides a radiotherapy apparatus (100) to generate both photon and electron beam mounted with dual KV beam ray source used for stereotactic imaging and CBCT (Cone Beam Computed Tomography) image with a greater FOV (Field Of View). The apparatus (IOO) comprises of a ring gantry (101), which includes at least two KV sources (102a and 102b), at least two movable detector (103 and 104) and a LINAC X-ray tube (106). The two movable detectors (103, 104) include a first movable detector (104) and a second movable detector (103). The second movable detector (103) has mechanism capture a half fan mode of X-ray beam of imaging radiation with a greater FOV having 250450 mm. The half fan mode of X ray is captured by moving the second movable detector (103) or first movable detector (104) further towards the ISO centre (105) of the ring gantry (101).

Computer generated three-dimensional models of microstructural features based on stereomicroscopy

3D information may be extracted from two 2D images by capturing a first image of a sample at a first orientation. The sample may be titled at a second or different orientation, resulting in a second image of the titled sample to be captured. Third dimension of information may be extracted from the images.

X-ray imaging apparatus, medical image processing apparatus, X-ray imaging method and medical image processing method

According to one embodiment, an X-ray imaging apparatus includes an X-ray image acquisition unit, a control system and a display processing part. The X-ray image acquisition unit acquires X-ray image data of an object by using at least one imaging system. The control system controls the imaging system to acquire X-ray image data corresponding to different directions by reciprocating the imaging system repeatedly. The display processing part acquires X-ray image data for stereoscopic viewing out of the X-ray image data corresponding to the different directions to generate and display stereoscopically visible image data on a display unit based on the X-ray image data for the stereoscopic viewing. The X-ray image data for the stereoscopic viewing are acquired in a period without a motion or a possibility of the motion in an imaging part of the object.

3-DIMENSIONAL X-RAY IMAGER

The invention utilizes one exposure without moving parts to provide multiple x-ray views of an object. It relies on a 3D detector, which can be a stack of film plates, and a specified focusing x-ray optic. The x-ray optic, discussed below, allows collection of x-rays from a localized volume, just like an ordinary optical lens, and the stacked film plate, or other 3D detector design, allows collection of the multiple focal plane information from one line of sight.

APPARATUS AND METHOD FOR THREE-DIMENSIONAL INSPECTION OF AN OBJET BY X-RAYS
20190139244 · 2019-05-09 ·

An apparatus and method for three-dimensional inspection of an object by X-rays. The apparatus includes an X-ray generator and a digital imaging device spaced from each other by a distance which defines a magnification by 1 on the imaging device. The apparatus also includes a means for moving the X-ray generator and identically the imaging device by unitary movements in two orthogonal directions. Each unitary movement corresponds to an integer number fraction of the side of the imaging device, and obtains, by successive shots after each unitary movement, a matrix set of sub-images overlapping in the plane of extension of the imaging device. Each sub-image has a center with coordinates in a plane of magnification equal to N. An image processing means performs magnification of each sub-image and determines a stretch factor enabling the coincidence of the sub-images representing all or part of a predefined element of interest.

X-ray imaging system comprising a shutter and method

An X-ray imaging system includes an X-ray detector; a plurality of X-ray sources configured to illuminate the X-ray detector from different perspectives; a shutter in a transmission plane between each X-ray source controlling transmission of X-rays from each X-ray source to the X-ray detector; and a processor configured to receive and process X-ray data from the X-ray detector. The shutter may be configured to illuminate the X-ray detector alternately with each X-ray source. The processor may determine 3D information about an object from the processed X-ray data. Also provided are methods for processing X-ray data and different embodiments of shutters to alternately illuminate X-ray detectors.
