Image processing apparatus, ultrasound diagnosis apparatus, and image processing method
An image processing apparatus of an embodiment includes a combined image generator and a controller. The combined image generator projects, on three-dimensional data indicating three-dimensional heart function information obtained from a first volume data group obtained by imaging the heart of a subject, a three-dimensional shape of blood vessels nourishing a cardiac muscle included in second volume data obtained by imaging the heart, thereby producing three-dimensional combined data, and produces combined image data in which the three-dimensional combined data is developed on a surface. The controller causes a display unit to display the combined image data.

A breast imaging apparatus includes a radiation source that irradiates a breast of a subject with radiation, a radiation detector that detects the radiation transmitted through the breast to output a radiographic image, and an ultraviolet light source that performs irradiation of ultraviolet light. The ultraviolet light source irradiates an imaging table, a face guard, a pressing plate, and the like with the ultraviolet light in a case where a turn-on command signal input from an operator through an input device is input.
MEASURING OXYGENATION CHANGES IN TISSUE AS A MARKER FOR VASCULAR FUNCTION
A method and system for processing imaging data of a tissue in an individual following a change in oxygenation or blood flow in tissue, for assessing tissue function. Test images are registered with a baseline image, providing registered images. The registered images may be compared to assess variations in the change in the tissue in response to changes in oxygenation or blood flow of the tissue shown in the images. The change in oxygenation or blood flow in the tissue may be quantified and plotted in a parametric plot or displayed in a parametric map to assess whether the change in oxygenation or blood flow, corresponding to a change in signal intensity, is abnormal following a stress event or under other conditions, to assess microvascular or macrovascular function.
Integrated microtomography and optical imaging systems
An integrated microtomography and optical imaging system includes a rotating table that supports an imaging object, an optical stage, and separate optical and microtomography imaging systems. The table rotates the imaging object about a vertical axis running therethrough to a plurality of different rotational positions during a combined microtomography and optical imaging process. The optical stage can be a trans-illumination, epi-illumination or bioluminescent stage. The optical imaging system includes a camera positioned vertically above the imaging object. The microtomography system includes an x-ray source positioned horizontally with respect to the imaging object. Optical and x-ray images are both obtained while the imaging object remains in place on the rotating table. The stage and table are included within an imaging chamber, and all components are included within a portable cabinet. Multiple imaging objects can be imaged simultaneously, and side mirrors can provide side views of the object to the overhead camera.
METHOD FOR FACILITATING A TOOTH REPOSITIONING DENTAL TREATMENT
A method for facilitating a tooth repositioning dental treatment includes: receiving a CT scan of a patient's oral dental structure, receiving an optical scan of the patient's oral dental structure, aligning the CT scan and the optical scan, establishing an initial model of the patient's oral dental structure based on the CT scan and the optical scan, simulating tooth movements to produce a final model of the patient's oral dental structure after the tooth repositioning dental treatment, generating a plurality of models of the patient's oral dental structure representing successive tooth movements from the initial model to the final model, and preparing dental aligners based on the plurality of models of the patient's oral dental structure.
Devices systems and methods for coronary intervention assessment, planning, and treatment based on desired outcome
The present disclosure relates generally to the assessment and treatment of vessels, including for percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG). For example, some embodiments of the present disclosure are suited for identifying the available intervention technique(s) suitable to achieve a desired outcome selected or input by a user. For example, in some implementations a method comprises receiving pressure measurements obtained by one or more intravascular pressure-sensing instruments positioned within a vessel of a patient; receiving an input from a user regarding a desired pressure value for the vessel of the patient; identifying an available treatment option based on the received pressure measurements and the desired pressure value; and outputting, to a display device, a screen display including a visual representation of the available treatment option. Related devices and systems are also described.

Method of classification of organs from a tomographic image
The present invention relates to a method for classification of an organ in a tomographic image. The method comprises the steps of receiving (102) a 3-dimensional anatomical tomographic target image comprising a water image data set and a fat image data set, each with a plurality of volume elements, providing (104) a prototype image comprising a 3-dimensional image data set with a plurality of volume elements, wherein a sub-set of the volume elements are given an organ label, transforming (106) the prototype image by applying a deformation field onto the volume elements of the prototype image such that each labeled volume element for a current organ is determined to be equivalent to a location for a volume element in a corresponding organ in the target image, and transferring (108) the labels of the labeled volume elements of the prototype image to corresponding volume elements of the target image.
IMAGING DEVICE AND METHOD FOR GENERATING AN IMAGE OF A PATIENT
The present invention relates to an imaging device (100) for generating an image of a patient (P), the imaging system (100) comprising: a camera arrangement (10), which is configured to provide a first image information (I1) of the patient (P) using a first wavelength band, and which is configured to provide a second image information (I2) of the patient (P) using a second wavelength band. The first wavelength band and the second set of wavelength band are different; and the first and/or second image information comprises landmark information of landmarks (M) of a patient (P).

OUTSIDE-FOV ACTIVITY ESTIMATION USING SURVIEW AND PRIOR PATIENT DATA IN POSITRON EMISSION TOMOGRAPHY
A radioemission scanner (12) is operated to acquire tomographic radioemission data of a radiopharmaceutical in a subject in an imaging field of view (FOV). An imaging system is operated to acquire extension imaging data of the subject in an extended FOV disposed outside of and adjacent the imaging FOV along an axial direction (18). A distribution of the radiopharmaceutical in the subject in the extended FOV is estimated based on the extension imaging data, and further based on a database (32) of reference subjects. The tomographic radioemission data are reconstructed to generate a reconstructed image (26) of the subject in the imaging FOV. The reconstruction includes correcting the reconstructed image for scatter from the extended FOV into the imaging FOV based on the estimated distribution of the radiopharmaceutical in the subject in the extended FOV.
