Processing logic makes a comparison between first image data and second image data of a dental arch and determines a plurality of spatial differences between a first representation of the dental arch in the first image data and a second representation of the dental arch in the second image data. The processing logic determines that a first spatial difference is attributable to scanner inaccuracy and that a second spatial difference is attributable to a clinical change to the dental arch. The processing logic generates a third representation of the dental arch that is a modified version of the second representation, wherein the first spatial difference is removed in the third representation, and wherein the third representation comprises a visual enhancement that accentuates the second spatial difference.

A multi-modality imaging system allows for selectable photoelectric effect and/or Compton effect detection. The camera or detector is a module with a catcher detector. Depending on the use or design, a scatter detector and/or a coded physical aperture are positioned in front of the catcher detector relative to the patient space. For low energies, emissions passing through the scatter detector continue through the coded aperture to be detected by the catcher detector using the photoelectric effect. Alternatively, the scatter detector is not provided. For higher energies, some emissions scatter at the scatter detector, and resulting emissions from the scattering pass by or through the coded aperture to be detected at the catcher detector for detection using the Compton effect. Alternatively, the coded aperture is not provided. The same module may be used to detect using both the photoelectric and Compton effects where both the scatter detector and coded aperture are provided with the catcher detector. Multiple modules may be positioned together to form a larger camera, or a module is used alone. By using modules, any number of modules may be used to fit with a multi-modality imaging system. One or more such modules may be added to another imaging system (e.g., CT or MR) for a multi-modality imaging system.

A method includes placing a set of electrodes on a body surface of a patient's body. The method also includes digitizing locations for the electrodes across the body surface based on one or more image frames using range imaging and/or monoscopic imaging. The method also includes estimating locations for hidden ones of the electrodes on the body surface not visible during the range imaging and/or monoscopic imaging. The method also includes registering the location for the electrodes on the body surface with predetermined geometry information that includes the body surface and an anatomical envelope within the patient's body. The method also includes storing geometry data in non-transitory memory based on the registration to define spatial relationships between the electrodes and the anatomical envelope.

A method of identifying injury to soft connective tissues in complicated body joints deploys use of motion x-ray images as the joint moves to identify suspected abnormal pathology followed by Dynamic Upright MRI images of the joint under conditions that express the abnormal pathology. The Dynamic Upright MRI parameters are based on the suspected pathology. The method is particularly useful in detecting disco/ligamentous and other injuries that often times will not be visualized on conventional recumbent MRI, or static x-rays.

One or more techniques and/or systems described herein provide for generating a radiographic image and ultrasound image depicting parallel planes of an object under examination and may be used in conjunction with radiographic or ultrasound techniques known to those in the field (e.g., x-ray tomosynthesis, computed tomography ultrasound imaging, etc.). An ultrasound frontend component is configured to transmit ultrasound waves in a direction substantially parallel to a trajectory of radiation. In one example, one or more radiographic images of an object are spatially coincident to one or more ultrasound images of the object in the same position and/or geometric shape/volume, and the images may be combined to generate a combined image depicting features of the ultrasound image (e.g., the sensitivity of the ultrasound image) and features of the radiographic image (e.g., the morphological details of the radiographic image).

An apparatus, system, and method are disclosed for mapping the location of a nerve. The apparatus includes at least one stimulation module, a stimulation detection module, a distance module, and a mapping module. The stimulation module stimulates a nerve with an electrical stimulation current from at least one stimulation electrode. A stimulation detection module detects a muscle reaction resulting from stimulation of the nerve by the at least one stimulation electrode. The distance module uses information from the at least one stimulation electrode and from the stimulation detection module to calculate a distance between the at least one stimulation electrode and the nerve. The mapping module maps a location on the nerve using at least two distances calculated by the distance module and position information of the at least one stimulation electrode for each of the at least two distances calculated.

Systems and methods for locating abnormalities within a breast and generating mappings of structures, such as ducts, within the breast. First imaging data may be acquired for a breast from a first imaging modality and second imaging data for the breast from a second imaging modality. The first imaging data is co-registered with the second imaging data, such that the first imaging data and the second imaging data share a common coordinate space. Based on the second imaging data, a plurality of structures within the breast are mapped to generate a mapping of the plurality of structures. From at least one of the first imaging data or the second imaging data, the abnormality in the breast is located. The mapping of the plurality of structures and the located abnormality in the breast may be concurrently displayed. A statistical analysis of the mapping of the breast structures may also be performed.

A method and device, e.g. a C-arm device, for radiographic and nuclear imaging of an object by means of x-ray and gamma emission imaging. The device comprises a support installation with opposed first and second support members, wherein an x-ray source is mounted on the first support member and an x-ray detector on the second support member. The first support member is additionally provided with at least two gamma cameras that are each located adjacent the x-ray source. Each of said at least two gamma cameras comprising a collimator with one or more collimator openings and a gamma radiation detector. Each of the at least two gamma cameras has an associated field of view. The fields of view of the gamma cameras overlap partly, said overlap defining a focus volume that is seen by the at least two gamma cameras. The focus volume is located between the x-ray source and the x-ray detector so that the x-ray beam passes through the focus volume and the focus volume F is seen by the x-ray detector. The x-ray source, x-ray detector, and gamma cameras are maintained in a stationary acquisition position during x-ray and gamma image data acquisition of x-ray and gamma radiation images respectively, which images are fused into a fused image.

An imaging system comprises a light field camera (3) for recording a hyperspectral light field (CLF). The system also comprises a light projector (4) for projecting a light field in visible light (PLF). The camera and the projector share a common optical axis. The projector projects a light field (PLF) based on the hyperspectral light field (CLF) captured by the light field camera.

The invention includes imaging catheters having image collectors co-located with radiopaque labels, methods of using the imaging catheters, and systems for locating the position of intravascular images within the body. In some instances, an angiogram is used to determine the precise location of the co-located radiopaque labels, and thus, the position of the intravascular image.
