A method for ultrasound image processing having steps of receiving sequences of ultrasound images imaging an anatomical feature of interest during two cardiac cycles one in the absence of, and the other in the presence of, an invasive medical device in said ultrasound images, each ultrasound image corresponding to a different phase of said cardiac cycle. The invasive medical device may at least partially obscure the anatomical feature of interest for each ultrasound image of the further sequence. The location of the invasive medical device is tracked and isolated in the ultrasound image, and the isolated invasive medical device is inserted into an ultrasound image of the first sequence of a corresponding phase of the cardiac cycle in the tracked location. The method also controls a display device to display the first sequence of ultrasound images including the inserted invasive medical device.

An ultrasound diagnostic apparatus (1) includes a time phase search period specifying unit (16) that specifies a time phase search period in each heartbeat period on the basis of Doppler data; and a frame specifying unit (12) that specifies at least one of B-mode data of a frame with a maximum diameter of a blood vessel or B-mode data of a frame with a minimum diameter of the blood vessel in each heartbeat period by analyzing the B-mode data of a plurality of frames in the time phase search period specified by the time phase search period specifying unit (16).

A system and method for tracking an anatomical structure over time based on Pulsed-Wave (PW) Doppler signals of a Multi-Gated Doppler (MGD) signal is provided. The method may include identifying a gate corresponding with a selected anatomical structure. The method may include analyzing an MGD signal to track the selected anatomical structure over an extended period of time by selecting, at a plurality of sample times during the extended period of time, a PW Doppler signal from a plurality of PW Doppler signals of the MGD signal. Each of the selected PW Doppler corresponds with the selected anatomical structure at the particular sample time. The method may include presenting a continuous PW Doppler signal generated from each of the PW Doppler signals selected at each of the sample times during the extended period of time at a display system.

Methods for processing two-dimensional ultrasound images from an intracardiac ultrasound imaging catheter provide improved image quality and enable generating three-dimensional composite images of the heart. Two-dimensional ultrasound images are obtained and stored in conjunction with correlating information, such as time or an electrocardiogram. Images related to particular conditions or configurations of the heart can be processed in combination to reduce image noise and increase resolution. Images may be processed to recognize structure edges, and the location of structure edges used to generate cartoon rendered images of the structure. Structure locations may be averaged over several images to remove noise, distortions and blurring from movement.

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.

An ultrasound imaging system performs spectral Doppler processing in a manner that considers a physiological cycle of a subject. In one embodiment, gaps in a spectral Doppler signal are filled taking by a processor that analyzes changes in the spectral Doppler signal caused by a physiological cycle. Spectral Doppler data are scaled to fit with the data occurring before and after a gap. The firing order of an interleaved imaging mode can also be adjusted so that spectral Doppler imaging is not interrupted during pre-defined or user defined portions of a physiological cycle.

Introduced here approaches to developing, training, and implementing algorithms to cardiac dysfunction through automated analysis of physiological data. As an example, a model may be developed and then trained to quantify left and right ventricular dysfunction using electrocardiogram waveform data that is associated with a population of individuals who are diverse in terms of age, gender, ethnicity, socioeconomic status, and the like. This approach to training allows the model to predict the presence of left and right ventricular dysfunction in a diverse population. Also introduced here is a regression framework for predicting numeric values of left ventricular ejection fraction.
