Systems and methods are disclosed that facilitate obtaining two dimensional (2D) ultrasound images, using two or more ultrasound imaging modes or modalities, to generate 2D multi-parametric ultrasound (mpUS) images and/or to generate a three-dimensional (3D) mpUS image. The different ultrasound imaging modes acquire images in a common frame of reference during a single procedure to facilitate their registration. The mpUS images (i.e., 2D or 3D) may be used for enhanced detection of suspicious regions.

An ultrasonic diagnostic apparatus according to an embodiment includes a rendering controller, a detector, and a voxel data generator. The rendering controller divides three-dimensional data constituted by voxel data into a plurality of slice regions, rearranges the slice regions based on a sight line direction in which the voxel data is observed, and performs volume rendering on the voxel data in which the slice regions have been rearranged so as to generate image data. The detector detects image quality information indicating image quality of image data that is generated by the rendering controller. The voxel data generator rearranges the voxel data constituting the three-dimensional data based on the image quality information detected by the detector based on the sight line direction.

A method and apparatus for implementing scar tissue identification using a processor coupled to a memory is disclosed. The method and apparatus receive a first modality and a second modality. The first modality is of a first type. The second modality is of a second type, which is different from the first type. Each of the first modality and the second modality respectively describe organic tissue of a patient according to the first and second types. The method and apparatus cross reference the first modality and the second modality and generates improved image data for the first modality based on the cross referencing. The image data includes enhanced accuracy over or higher resolution than original data of the first modality.

A surgical system and method are provided that is configured to effect substituting a high resolution image created pre-surgery for a lower resolution image created in real time during surgery and simulating the real time position of the surgical site.

The present application provides an image display method and an ultrasound imaging system. The image display method includes performing a position adjustment operation on an initial volume view in an image display interface to obtain at least one reference volume view, storing position information of the at least one reference volume view, and creating at least one label to point to the position information, the at least one label being displayed in the image display interface.

An intraoral scanner system includes an intraoral scanner having an imaging device and a sensing face, and a computing device, communicatively coupled to the intraoral scanner. The computing device receives a first intraoral images of a three-dimensional intraoral object of a patient generated by the intraoral scanner corresponding to an intraoral scanning of the three-dimensional intraoral object of the patient. The computing device registers a first intraoral image of the first intraoral images relative to a second intraoral image of the first intraoral images using a model of the three-dimensional intraoral object that existed prior to the intraoral scanning.

Some embodiments are directed to a method for quantitative visualization of uterine strain. The method includes receiving a number of 2D or 3D image frames acquired via an imaging technique and selecting a number of confidential points, determining the orientation of the uterus using the confidential points, selecting a region of interest, generating a grid of tracking points inside the region of interest and tracking and estimating the displacement of tracking points between frames. From a varying distance between each couple or set of tracking points, a strain is calculated. The orientation of the grid of tracking points and of the calculated strain is dependent on the determined orientation of the uterus.

A method for determining the size of a bicuspid annulus of bicuspid, including acquiring an image of the heart including the left ventricle and the aorta; generating a first plane, which includes a line that passes through two base points in the bicuspid of the image of the heart; and generating multiple second planes, which are obtained per each rotation, while rotating the first plane multiple times by a predetermined angle about the line that passes through the two base points; measuring the cross-sectional area of each of at least one of the left ventricle and the aorta, which are formed on the first plane and the multiple second planes; selecting a plane for measuring the size of a bicuspid annulus among the first plane and the multiple second planes based on the measured cross-sectional area; and measuring the size of the bicuspid annulus based on the selected plane.

Scan planes in acquisition of ultrasound images and dimensional measurements of objects represented in the images are determined by: defining a body to be examined and a predetermined orientation of the scan plane which intersects said body along which plane at least one ultrasound image is acquired; providing machine learning algorithm for verifying orientation and position of the scan plane, said algorithm trained with database of known cases which correlate image data of an image of a body previously examined and similar to said body with the position and orientation of the scan plane; reporting the scan plane does not correspond to the position and/or orientation of said predetermined scan plane; repeating the scan by changing the position and/or the orientation of the scan plane and repeating the steps as long as the position and orientation of the scan plane do not correspond to those of the predetermined scan plane.

A processor analyzes an image obtained by imaging a subject including a tubular structure in which a fluid flows, thereby deriving fluid information regarding flow of the fluid at each of pixel positions in the tubular structure. The processor sets a sampling interval for displaying the fluid information in accordance with a size of a region intersecting a center line of the tubular structure included in the image. The processor samples the fluid information at the set sampling interval and causes a display to display the fluid information.
