Abstract
An automated method for selecting image frames from a sequence of image frames for application of one or more anatomical/physiological assessment or quantification algorithms. In particular, the method is based on classifying a received sequence of image frames in accordance with an imaging view from which a sequence of image frames has been acquired. The method further includes determining for each frame in the sequence a sub-phase of the image frame within a cardiac cycle of the imaged heart of the subject. These determined parameters are used to identify one or more suitable frames for application of one or more predetermined algorithms, and/or can be used to identify one or more suitable algorithms for application to each, or a subset, of the frames.
Claims14
A method comprising:
- receiving a temporal sequence of ultrasound frames of a heart of a subject, spanning at least one heart cycle;
- determining a view represented by the sequence of frames, wherein the view is an imaging view from which the sequence of frames has been acquired;
- detecting within each frame a motion state of one or more anatomical features, each having a cyclical motion pattern over a cardiac cycle;
- determining for each frame a phase point of the frame within a cardiac cycle, the phase point being a sub-phase point of one of systole or diastole phases, wherein the determining of the phase point of each frame is based on the detected motion state of the one or more anatomical features;
- applying one or more cardiac valve analysis algorithms, each algorithm configured to receive one or more input ultrasound frames representative of the heart in a pre-defined one or more views, and at a pre-defined one or more phase points of the cardiac cycle, wherein the one or more input image frames provided to each algorithm are selected based on the determined view and phase point of each of the received frames;
- and
- generating a data output representative of an output of each of the one or more algorithms.
A processing arrangement comprising:
- an input/output;
- and
- one or more processors adapted to:
- receive at the input/output a temporal sequence of ultrasound frames of a heart of a subject, spanning at least one heart cycle;
- determine a view represented by the sequence of frames, wherein the view is an imaging view from which the sequence of frames has been acquired;
- detect within each frame a motion state of one or more anatomical features, each having a cyclical motion pattern over a cardiac cycle;
- determine for each frame a phase point of the frame within a cardiac cycle, the phase point being a sub-phase of one of systole or diastole phases, wherein the determination of the phase point of each frame is based on the detected motion state of the one or more anatomical features;
- apply one or more cardiac valve analysis algorithms, each algorithm configured to receive one or more input ultrasound frames representative of the heart in a pre-defined one or more views, and at a pre-defined one or more phase points of the cardiac cycle, wherein the one or more input image frames provided to each algorithm is selected based on the determined view and phase point of each of the received frames;
- and
- generate a data output representative of an output of each of the one or more algorithms.
