Three dimensional x-ray imaging system
Three dimensional x-ray imaging systems are described in this application. In particular, this application describes a 3D dental intra-oral imaging (3DIO) system that collects a series of 2D image projections. The x-ray imaging system comprises a housing, an x-ray source attached to a articulating or motion gantry configured to move the source within the housing to multiple positions, an x-ray detector array located on an opposite side of an object to be imaged from the x-ray source, where the detector array is synchronized with the x-ray source to capture 2D images of the object when the x-ray source is located in multiple imaging positions, and a processor configured to accept the 2D images and reconstruct a 3D image. The multiple imaging positions can be located on a plane substantially parallel to the x-ray detector array. Other embodiments are described.
X-ray system error tracking and calibration
Mechanical image acquisition systems (such as medical C-arms) frequently accumulate geometrical errors which must be calibrated out using a calibration phantom. A more frequent regime of system calibration implies a less frequent use of the C-arm for clinical applications. The present application proposes to identify common biases between the acquired projection frame sequences from the same mechanical image acquisition system in first and second acquisitions, and to compare this to expected calibration data of the mechanical image acquisition system to generate frame deviation measures. If a resemblance between the first and second sequences of frame deviation measures is obtained, one or more calibration actions are performed (such as alerting the user that calibration should be provided, and/or automatically correcting for the geometry deviation).
Setting an x-ray emission unit
Setting an x-ray emission unit includes acquiring image data with the aid of a number of image recording units. A body region to be recorded of an examination object is identified based on the image data. Position data of the body region to be recorded is established, and the x-ray emission unit is set using the position data.
X-ray imaging apparatus and method for controlling the same
An imaging apparatus includes a camera to capture a camera image of a target disposed on an examination table; an X-ray source to generate and radiate X-rays; a memory to store imaging protocols; a display; and a controller. The controller is configured to receive information regarding a selection of an imaging protocol, identify a position of an imaging region of the target based on the camera image, the imaging region corresponding to the selection of the imaging protocol and the camera image being acquired with the examination table at a first distance from the X-ray source, control the display to display the camera image of the target and an indicator indicating the imaging region on the camera image based on the identified position, and control the X-ray source to radiate the X-rays toward the target disposed on the examination table at a second distance from the X-ray source.
Coordinated motion of a rotating 2D x-ray imager and a linear accelerator
A method of and apparatus for operating a radiation treatment delivery system. The method includes generating, by a processing device, a set of instructions for a volumetric imager based on a set of directionalities for a radiation beam of a linear accelerator (LINAC) to avoid a collision between the volumetric imager and the LINAC, wherein the set of instructions comprises physical locations of the volumetric imager and timing values corresponding to the physical locations. The method further includes operating the volumetric imager during the radiation treatment delivery according to the set of instructions.
Radiography control apparatus, radiographic imaging apparatus, and radiographic imaging system
A console 3 included in a radiographic imaging system 100 includes a hardware processor that acquires a plurality of radiographs from a radiographic imaging apparatus 2 that repeatedly generates radiographs in a predetermined cycle, determines whether there is an anomaly that occurred during radiography of the acquired radiographs, and on determining that there is an anomaly, performs a predetermined anomaly operation.
IMAGING SUPPORT DEVICE, AND OPERATION METHOD AND OPERATION PROGRAM FOR THE SAME
An imaging support device used in a radiography apparatus including a radiation source and a radiation image detector that detects a radiation image of a subject on the basis of radiation emitted from the radiation source and transmitted through the subject, and includes an optical camera that optically images a region including an irradiation field of the radiation applied to the subject from the radiation source, and at least one processor. The processor acquires, as a first optical image, an optical image indicating the subject in the region by causing the optical camera to perform imaging in conjunction with radiography performed by the radiography apparatus, and stores a radiation image acquired through the radiography and the first optical image in a storage unit in association with each other.
