A medical image processing apparatus according to an embodiment includes processing circuitry. The processing circuitry obtains X-ray images that are sequentially collected during a partial period of time in a cardiac phase of a subject who has a device inserted into the body. Then, the processing circuitry identifies a characteristic region of the device captured in a plurality of obtained X-ray images, and performs registration in which the position of the characteristic region identified in a reference image, which is one of the plurality of X-ray images, serves as the reference position, and in which the position of the characteristic region identified in the plurality of X-ray images collected after the reference image is adjusted based on the reference position.

A method for distinguishing between types of intraoral areas of interest (AOIs) includes receiving or generating a first 3D model comprising teeth; receiving or generating a second 3D model comprising the teeth; comparing the first 3D model to the second 3D model; determining a difference between the first 3D model and the second 3D model at a dental site comprising a tooth; determining an intraoral AOI that is associated with the difference; determining whether the difference comprises a first type of change indicative of a first type of intraoral AOI or a second type of change indicative of a second type of intraoral AOI; and responsive to determining that the difference comprises the first type of change, determining that the intraoral AOI is the first type of intraoral AOI and generating an indicator of the first type of intraoral AOI for the tooth.

3D image data of a skeletal portion is acquired. A location of a proximal portion of a tool is calculated and a location is derived of a distal portion of the tool with respect to the skeletal portion, with respect to the 3D image data. A display indicates the derived location. First and second 2D images of the distal portion of the tool are acquired from two different poses of a 2D imaging device with respect to the subject and registered with the 3D image data. The location of the distal portion with respect to the 3D image data of the skeletal portion is determined based on the registration and an identified location of the distal portion within the 2D x-rays. Based upon the determined location, the display updates the indicated location of the distal portion. Other embodiments are also described.

A radiation image capturing system includes a capturing room and a console. The capturing room includes a bucky apparatus, a radiation irradiating apparatus and a detecting unit. A plurality of portable radiation image capturing apparatuses can be loaded on the bucky apparatus. The radiation irradiating apparatus is able to simultaneously irradiate radiation to the plurality of portable radiation image capturing apparatuses. The console is associated with the capturing room and obtains capturing order information. The console allows the portable radiation image capturing apparatuses to advance to a capturing possible state when the console judges that capturing in the capturing order information is long length capturing. The console allows only one of the portable radiation image capturing apparatuses to advance to the capturing possible state when the console judges that the capturing is not the long length capturing.

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.

The present apparatus, system, and method relate to reliably capturing multiple x-ray images for later combination. An exposure shield blocks a portion of the x-rays emitted from a traditional emitter and collimator. The orientation of exposure shield may then be modified to block a second portion of x-rays while ensuring appropriate overlap of the captured images without intentionally moving the emitter or collimator and without the need for a patient to wear protective garb.

A recording and reconstruction of image data of a predetermined object of an examination object is performed by an x-ray system. The x-ray system determines a number of elliptical cylinders so that the object is arranged entirely in the volumes of the cylinders. Data within each of the cylinders is recorded by the x-ray system. The image data of the object is reconstructed based on the data recorded for each of the cylinders.

A method and apparatus for Cone-Beam Computerized Tomography, (CBCT) is configured to increase the maximum Field-Of-View (FOV) through a composite scanning protocol and includes acquisition and reconstruction of multiple volumes related to partially overlapping different anatomic areas, and the subsequent stitching of those volumes, thereby obtaining, as a final result, a single final volume having dimensions larger than those otherwise provided by the geometry of the acquisition system.

A radiographing system and a radiographing method capable of improving the image quality of a long-sized image by appropriately correcting scattered radiation are disclosed. The radiographing system includes a plurality of radiation detecting apparatuses that can detect radiation and output radiographic images, a composition processing unit configured to generate a long-sized image by composing a plurality of radiographic images acquired from the plurality of radiation detecting apparatuses, and a scattered radiation correction unit configured to perform processing for correcting scattered radiation for a radiographic image output from at least one of the plurality of radiation detecting apparatuses.

A radiographic imaging control method includes combining a plurality of images by applying a first weight to the plurality of images, displaying a composite image, acquired by combining the plurality of images, newly receiving a second weight with respect to the composite image, recombining the plurality of images based on the received second weight, and displaying a recombined image, acquired by recombining the plurality of images.
