Abstract
A medical imaging apparatus for generating a three-dimensional image of a vessel includes a catheter including a probe and insertable into the vessel, the catheter being configured to generate cross-sectional images of the vessel from ultrasonic signals emitted from the probe and received by the probe, and a processor configured to: control the catheter to emit the signals and acquire a series of cross-sectional images of the vessel therefrom, calculate a series of feature values of the vessel corresponding to the series of cross-sectional images, determine local maximums of variations in the series of feature values, select two or more of the cross-sectional images corresponding to the local maximums, and generate a three-dimensional image of the vessel using the selected images.
Claims20
A medical imaging apparatus for generating a three-dimensional image of a vessel, comprising:
- a catheter including a probe and insertable into the vessel, wherein the catheter is configured to generate cross-sectional images of the vessel from signals emitted from the probe and received by the probe;
- and
- a processor configured to:
- control the catheter to emit the signals and acquire a series of cross-sectional images of the vessel therefrom,
- calculate a series of feature values of the vessel corresponding to the series of cross-sectional images,
- determine local maximums of variations in the series of feature values,
- select two or more of the cross-sectional images corresponding to the local maximums, and
- generate a three-dimensional image of the vessel using the selected images.
A method for generating a three-dimensional image of a vessel, the method comprising:
- controlling a catheter including a probe and inserted into the vessel to emit signals and acquiring a series of cross-sectional images of the vessel therefrom;
- calculating a series of feature values of the vessel corresponding to the series of cross-sectional images;
- determining local maximums of variations in the series of feature values;
- selecting two or more of the cross-sectional images corresponding to the local maximums;
- and
- generating a three-dimensional image of the vessel using the selected images.
A non-transitory computer readable storage medium storing a program causing a computer to execute a method for generating a three-dimensional image of a vessel, the method comprising:
- controlling a catheter including a probe and inserted into the vessel to emit signals and acquiring a series of cross-sectional images of the vessel therefrom;
- calculating a series of feature values of the vessel corresponding to the series of cross-sectional images;
- determining local maximums of variations in the series of feature values;
- selecting two or more of the cross-sectional images corresponding to the local maximums;
- and
- generating a three-dimensional image of the vessel using the selected images.
