Abstract
A method of detecting motion of a patient's breast tissue during medical imaging, including obtaining image data of the patient's breast tissue; processing the image data to generate a set of image slices that collectively depict the patient's breast tissue; detecting a high contrast object on one or more image slices of the set of image slices; identifying an artifact, associated with the high contrast object, on one or more image slices of the set of image slices; measuring a physical attribute of the artifact; measuring a deviation of the physical attribute from a baseline; determining the deviation exceeds a predetermined threshold; and generating, in response to determining the deviation exceeds the predetermined threshold, a motion indicator.
Claims21
A method of detecting motion of a patient's breast tissue during medical imaging, the method comprising:
- obtaining image data of the patient's breast tissue;
- processing the image data to generate a set of image slices that collectively depict the patient's breast tissue;
- detecting a high contrast object on one or more image slices of the set of image slices;
- identifying an artifact, associated with the high contrast object, on one or more image slices of the set of image slices, wherein the artifact is a projection of the high contrast object identified on an out-of-focus image slice;
- measuring a physical attribute of the artifact, wherein the physical attribute includes one or more of a width, a length, a height, and an opacity;
- measuring a deviation of the physical attribute from a baseline;
- determining the deviation exceeds a predetermined threshold;
- and
- generating, in response to determining the deviation exceeds the predetermined threshold, a motion indicator.
(canceled)
A system comprising:
- a computer-readable memory storing executable instructions;
- and
- one or more processors in communication with the computer-readable memory, wherein, when the one or more processors execute the executable instructions, the one or more processors perform:
- obtaining image data of the patient's breast tissue;
- processing the image data to generate a set of image slices that collectively depict the patient's breast tissue;
- detecting a high contrast object on one or more image slices of the set of image slices;
- identifying an artifact, associated with the high contrast object, on one or more image slices of the set of image slices, wherein the artifact is a projection of the high contrast object identified on an out-of-focus image slice;
- measuring a physical attribute of the artifact, wherein the physical attribute includes one or more of a width, a length, a height, and an opacity;
- measuring a deviation of the physical attribute from a baseline;
- determining the deviation exceeds a predetermined threshold;
- and
- generating, in response to determining the deviation exceeds the predetermined threshold, a motion indicator.
A non-transitory computer readable medium having stored thereon one or more sequences of instructions for causing one or more processors to perform:
- obtaining image data of the patient's breast tissue;
- processing the image data to generate a set of image slices that collectively depict the patient's breast tissue;
- detecting a high contrast object on one or more image slices of the set of image slices;
- identifying an artifact, associated with the high contrast object, on one or more image slices of the set of image slices, wherein the artifact is a projection of the high contrast object identified on an out-of-focus image slice;
- measuring a physical attribute of the artifact, wherein the physical attribute includes one or more of a width, a length, a height, and an opacity;
- measuring a deviation of the physical attribute from a baseline;
- determining the deviation exceeds a predetermined threshold;
- and
- generating, in response to determining the deviation exceeds the predetermined threshold, a motion indicator.
