One such system includes an ultrasound sensor, an electrocardiogram (EKG) sensor, an auscultation sensor, and a computing device. The computing device includes memory and a processor, and the processor receives signals from the ultrasound sensor, the EKG sensor, and the auscultation sensor. Artificial intelligence techniques may be employed for automatically analyzing the data obtained from the ultrasound sensor, the EKG sensor, and the auscultation sensor and producing a clinically-relevant determination based on a combined analysis of the data.

In an example, a system includes an ultrasound sensor configured to transmit ultrasound energy and receive ultrasound energy reflected in a region of a patient and one or more processors configured to generate a reference ultrasound image of the region of the patient based on a portion of the ultrasound energy that was received by the ultrasound sensor prior to a medical instrument or medical device causing obstruction in the received ultrasound energy, generate a live ultrasound image based on a current portion of the received ultrasound energy obtained by the ultrasound sensor, register the reference ultrasound image and the live ultrasound image, and control a display device to display the reference ultrasound image with at least a portion of the live ultrasound image.

An ultrasound guidance method and system for an ultrasound imaging system in which user-defined start and end locations define a volume to be imaged. Guidance instructions for an ultrasound process performed on the defined volume may thereby be generated, to help guide the movement of an ultrasound probe during the ultrasound imaging process. The movement of the ultrasound probe is monitored using an ultrasound probe tracker to ensure that the user is adhering to the guidance instructions.

A physiological information system includes a patient monitor configured to acquire a vital sign based on a vital sign signal of a subject, and an ultrasonic measuring apparatus configured to acquire ultrasonic images based on ultrasonic waves transmitted toward the subject and received from the subject. The patient monitor includes a storage device configured to store measured data of the vital signs in association with measurement dates and times, and to store the ultrasonic images in association with image capture timings, and a controller configured to display a screen on a display section based on data, including the measured data and the ultrasonic images, stored in the storage device.

An imaging system includes an imaging device (10) configured to acquire an image in a multi-beat acquisition mode. A quality scoring module (115) is stored in memory and is configured to evaluate changes in the image between portions of a multi-beat cycle to compute a quality score (136) indicating a suitability of the image. A display (118) is included for viewing the image and displaying the quality score as real-time feedback for the image.

Various systems and methods for generating images are provided. In some embodiments, the techniques can include acquiring a medical image and an associated motion characterization. The motion characterization can then be used to generate a plurality of gated image data sets, sorted by phase in the motion cycle. A new amplitude-based motion characterization curve is derived from the association of phases with amplitude-based characteristics in the phase gated images. This newly derived amplitude-based motion characterization curve can then be used to re-sort data according to amplitude-based gating techniques known in the field or with data driven optimization techniques.

The invention relates to the field of intravascular ultrasound (IVUS) imaging IVUS images of a vessel (6) are provided, which have been determined based on IVUS signals acquired at different acquisition locations (9, 10) along the length of the vessel and at different acquisition times. Moreover, pressure values are provided, which are indicative of the pressure within the vessel at the acquisition times, wherein a combined IVUS image is generated by combining provided IVUS images that have been determined based on IVUS signals acquired at acquisition times at which the pressure values differ by less than a predefined deviation threshold from a reference pressure value. This use of the pressure within the vessel as a selection criterion for combining IVUS images can ensure that only IVUS images are combined, which correspond to a same vessel wall motion state, thereby reducing artifacts in the combined IVUS image.

Disclosed is an ultrasound image processing apparatus (5) comprising an image processor arrangement (50) adapted to receive a first sequence (100) of ultrasound images (150) imaging an anatomical feature of interest (151) during a first full cardiac cycle in the absence of an invasive medical device (15) in said ultrasound images, each ultrasound image corresponding to a different phase of said cardiac cycle; receive a further sequence (100) of ultrasound images (150) imaging the anatomical feature of interest (151) during a further full cardiac cycle in the presence of the invasive medical device (15) in said ultrasound images, each ultrasound image corresponding to a different phase of said cardiac cycle said invasive medical device (15) at least partially obscuring the anatomical feature of interest, and for each ultrasound image of the further sequence: track the location of the invasive medical device in the ultrasound image; isolate the invasive medical device from the ultrasound image; and insert the isolated invasive medical device into an ultrasound image of the first sequence of a corresponding phase of the cardiac cycle in the tracked location; and control a display device to display the first sequence of ultrasound images including the inserted invasive medical device. Also disclosed are an ultrasound imaging system comprising such an ultrasound image processing apparatus and a computer program product facilitating the configuration of such an image processing apparatus in accordance with embodiments of the present invention.

According to one embodiment, an apparatus includes an acquisition unit and a generation unit. The acquisition unit specifies the cycle of pulses in a part that performs periodic motion based on blood flow information in the part. The generation unit rearranges a plurality of two-dimensional images of the part based on the cycle to generate a three-dimensional image.

The present application relates to an ultrasound fusion imaging method and an ultrasound fusion image navigation system. The ultrasound fusion imaging method includes a selection step, a registration step and a fusion step. The selection step is for selecting at least one ultrasound image from at least one previously stored piece of ultrasound video data according to an input instruction. The ultrasound video data includes an ultrasound image obtained by acquiring a target object in at least one plane and position indicating information corresponding to the ultrasound image. The registration step is for registering the selected at least one ultrasound image with a modality image. The registration process uses the location of the position indicating information of the at least one ultrasound image. The fusion step is for fusing the registered ultrasound image with the modality image.
