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 and/or automated detection of one or more suspicious regions. After identifying one or more suspicious regions, the mpUS images may be utilized with a real-time image to guide biopsy or therapy the region(s). All these processes may be performed in a single medical procedure.

A medical information processing system in an embodiment includes processing circuitry. The processing circuitry acquires an ultrasound image including an observation target and having additional information, positional information indicating a position of an ultrasound probe in a subject at time of collection of the ultrasound image, and a reference image obtained by taking an image of a region including the observation target at a time point other than the time of collection. The processing circuitry generates, based on the positional information, correspondence information in which the ultrasound image and the reference image are associated with each other. The processing circuitry causes an output unit to output the generated correspondence information.

The invention provides an ultrasound system including an ultrasound transducer array and a processor. The ultrasound transducer array comprises a plurality of transducer elements adapted to conform with a subjects body.

The processor is adapted to receive ultrasound signals acquired by the ultrasound transducer array. The processor is further adapted to partition the plurality of ultrasound signals according to a signal depth and, for each ultrasound signal partition, calculate a Doppler power. For each ultrasound signal, the processor identifies a depth of a fetal heartbeat based on the Doppler power of each ultrasound signal partition and identifies a fetal heart region based on the identified fetal heartbeat and a location of the at least two ultrasound transducers.

An ultrasound probe captures real-time images of patient anatomy, which are analyzed by a processor to extract salient features pertaining to an anatomical structure. By tracking the location and orientation of the ultrasound probe, a model of that anatomical structure can be created. A visual indication of the position of segments of the anatomical structure can be presented holographically to a user of an augmented reality headset to provide information extracted from the ultrasound imaging, such as holographic display of a model of the anatomical structure at the approximate location of the visual field of the headset corresponding to the physical location of the actual anatomy being viewed by a user, without presenting the entirety of the ultrasound image to the user.

An apparatus for remote interaction with a patient includes a local system including a physical element to interact with the patient, and a local electronic device with a camera to capture images of the physical element interacting with the patient, and a local display to display the images with a virtual representation of the physical element relative to the patient. The local electronic device obtains information dependent on position and orientation of the physical element interacting with the patient. A remote system includes a remote electronic device with a display to display the images of the physical element interacting with the patient, and an image based on the information. A remote input device controls position and orientation of the virtual representation displayed on the local display.
