The invention includes a method including the steps of obtaining a plurality of images, each of the images in the plurality having at least one corresponding region, generating a merged image, the merged image also having the corresponding region. The step of generating includes selecting an image source from the plurality of images to source image data for the corresponding region in the merged image by comparing attributes of the corresponding regions of the plurality of images to identify the image source having preferred attributes.

An intraoral scanner generates 2D images of a dental site and 3D intraoral scans of the dental site. The computing device receives the 2D images of the dental site and the 3D intraoral scans of the dental site from the intraoral scanner, generates a 3D model of the dental site based on the 3D intraoral scans of the dental site, and processes at least one of a) one or more of the 2D images of the dental site, b) one or more of the 3D intraoral scans of the dental site, or c) data from the 3D model of the dental site to identify one or more intraoral areas of interest (AOIs) at the dental site. The computing device determines a dental condition associated with the one or more intraoral AOIs, and determines a manner for scanning the one or more intraoral AOIs.

A processor is configured to generate a structure-highlighted synthesized two-dimensional image from a plurality of tomographic images, to detect a structure of interest from the plurality of tomographic images or the structure-highlighted synthesized two-dimensional image, and to set at least some of the plurality of tomographic images as either storage-required images or non-storage-required images based on a detection result of the structure of interest.

A radiographic image detection device subtracts a first offset image from a radiographic image to generate a primary corrected image, subtracts a second offset image from an immediately preceding offset image to generate an offset difference image, performs gain correction on the primary corrected image on the basis of a first gain image to generate a secondary corrected image, performs gain correction on the offset difference image on the basis of a second gain image to generate a gain-corrected offset difference image, performs a low-pass filtering process on the gain-corrected offset difference image, and subtracts the gain-corrected offset difference image subjected to the low-pass filtering process from the secondary corrected image to generate a tertiary corrected image.

Provided is an image processing apparatus for a C-arm, including: a movement control unit which moves a C-arm which irradiates a radiation onto a bone of a subject located on a table and detects the radiation which penetrates the bone to generate a projection image for the bone, along a predetermined route; an image acquiring unit which acquires a plurality of projection images generated by the moving C-arm at every predetermined interval; and an image processing unit which generates a combined projection image in which the plurality of acquired projection images is combined, and the predetermined interval may be an interval at which a continuous panoramic image may be generated by connecting the plurality of acquired projection images.

The present invention relates to matching a field of view for mobile 3D imaging, for example mobile C-arm 3D imaging In order to provide image data that is improved for comparing purposes, for example when using a mobile X-ray imaging system, first location information of a first reconstruction volume based on a first sequence of X-ray images of a region of interest of a subject acquired along a first trajectory in a first position of an X-ray imaging device is received. Further, a planned second trajectory for acquiring a second sequence of X-ray images in a second position of the X-ray imaging device is received and a resulting second reconstruction volume for the second sequence of X-ray images is calculated. Then, second location information for the second reconstruction volume is determined. Further, a degree of comparability for the first reconstruction volume and the second reconstruction volume is determined based on the first location information and the second location information. An adapted second trajectory is calculated that results in.

An imaging system is disclosed to include an elongate member supported by a plurality of wheels, where the elongate member is extendable in a horizontal axis such that a distance between two of the plurality of wheels is increased when the elongate member is extended in the horizontal axis; a trolley slidably secured to the elongate member, where the trolley includes a base portion and an upper portion. The base portion moves in the horizontal axis along the elongate member and the upper portion is rotatably mounted to the base portion, where the upper portion is configured to rotate at least 90 degrees relative to the base portion and elongate member.

A dynamic imaging quality control device performs quality control of dynamic imaging in which a dynamic state of a subject is imaged by irradiating the subject with radiation. The device includes a hardware processor that: determines a target frame image as a target of quality control from among multiple frame images constituting a dynamic image obtained by the dynamic imaging; generates quality information regarding quality of the dynamic imaging by using the determined target frame image; and outputs the quality information

A medical imaging system includes a movable station having a C-arm, a collector, an X-ray beam emitter, and a controller. The collector is attached to a first end of the C-arm. The X-ray beam emitter faces the collector to emit an X-ray beam in a direction of the collector and is attached to a second end of the C-arm. The controller moves one of the X-ray beam emitter and the collector to a first offset position along a lateral axis orthogonal to the arc, and obtains a first set of images by rotating the collector and the X-ray beam emitter along the arc about a scanned volume. The controller moves the one of the X-ray beam emitter and the collector to a second offset position along the lateral axis, and obtains a second set of images. The controller combines the first and second set of images to generate a three-dimensional image of the scanned volume.

The present disclosure relates to the generation of partial surface models from volumetric datasets for subsequent registration of such partial surface models to surface topology datasets. Specifically, given an object that is imaged using surface topology imaging and another volumetric modality, the volumetric dataset is processed in combination with an approach viewpoint to generate one or more partial surfaces of the object that will be visible to the surface topology imaging system. This procedure can eliminate internal structures from the surfaces generated from volumetric datasets, thus increases the similarity of the dataset between the two different modalities, enabling improved and quicker registration.
