Abstract
Example medical systems and techniques are disclosed. An example medical system includes memory and processing circuitry. The processing circuitry is configured to obtain angiography data. The processing circuitry is configured to determine, based on the angiography data, a location of a true lumen of a cardiac vessel. The processing circuitry is configured to determine a location of a distal portion of a medical instrument. The processing circuitry is configured to determine, based on the location of the true lumen and the location of the distal portion of the medical instrument, a navigation path for the distal portion of the medical instrument to the true lumen. The processing circuitry is configured to output a representation of the navigation path for display.
Claims20
A medical system comprising:
- memory configured to store angiography data of a patient;
- and
- processing circuitry communicatively coupled to the memory, the processing circuitry being configured to:
- obtain the angiography data;
- determine, based on the angiography data, a location of a true lumen of a cardiac vessel;
- determine a location of a distal portion of a medical instrument;
- determine, based on the location of the true lumen and the location of the distal portion of the medical instrument, a navigation path for the distal portion of the medical instrument to the true lumen;
- and
- output a representation of the navigation path for display.
A method comprising:
- obtaining, by processing circuitry, angiography data of a patient;
- determining, by the processing circuitry and based on the angiography data, a location of a true lumen of a cardiac vessel;
- determining, by the processing circuitry, a location of a distal portion of a medical instrument;
- determining, by the processing circuitry and based on the location of the true lumen and the location of the distal portion of the medical instrument, a navigation path for the distal portion of the medical instrument to the true lumen;
- and
- outputting, by the processing circuitry, a representation of the navigation path for display.
A non-transitory computer-readable storage medium storing instructions, which when executed cause processing circuitry to:
- obtain angiography data of a patient;
- determine, based on the angiography data, a location of a true lumen of a cardiac vessel;
- determine a location of a distal portion of a medical instrument;
- determine, based on the location of the true lumen and the location of the distal portion of the medical instrument, a navigation path for the distal portion of the medical instrument to the true lumen;
- and
- output a representation of the navigation path for display.
The method of example 16, wherein the lesion is a chronic total occlusion.
