Abstract
A method and system are provided for determining a navigation pathway for an invasive medical instrument in a blood vessel is provided. The method includes receiving a first medical image. The method further includes determining one or more parameters associated with the first medical image. Additionally, the method includes identifying a second medical image in a computer memory, based on the determined one or more parameters. Furthermore, the method includes modifying the second medical image based on the first medical image. The method also includes determining from the modified second medical image the navigation pathway for the invasive medical instrument.
Claims17
A method for determining a navigation pathway for navigating an invasive medical instrument inside a blood vessel, the method comprising:
- receiving, by a processor, a first medical image associated with a patient, the first medical image acquired during a first medical imaging procedure;
- determining, by the processor, one or more parameters associated with the first medical image;
- identifying, by the processor, a second medical image from a plurality of images associated with the patient based on the determined one or more parameters, the second medical image acquired during a second medical imaging procedure performed prior to the first medical imaging procedure;
- determining, by the processor, deviation between a structural orientation of one or more objects in the first medical image and one or more objects in the second medical image;
- modifying, by the processor, the second medical image based on deviation between the structural orientation of the one or more objects in the first medical image and the one or more objects in the second medical image;
- and
- determining, by the processor, the navigation pathway for navigating the invasive medical instrument inside the blood vessel using the second medical image;
- wherein the navigation pathway corresponds to the modified structural orientation of the one or more objects in the second medical image.
A system for determining a navigation pathway for navigating an invasive medical instrument inside a blood vessel, the system comprising:
- a processor;
- a medical database coupled to the processor;
- a memory coupled to the processor, the memory comprising a navigation module configured to:
- receive a first medical image associated with a patient;
- determine one or more parameters associated with the first medical image;
- identify a second medical image from a plurality of images associated with the patient based on the determined one or more parameters, the second medical image acquired during a medical imaging procedure prior to an acquisition of the first medical image;
- determine deviation between a structural orientation of one or more objects in the first medical image and one or more objects in the second medical image;
- modify the second medical image based on deviation between the structural orientation of the one or more objects in the first medical image and the one or more objects in the second medical image;
- and
- determine the navigation pathway for navigating the invasive medical instrument inside the blood vessel using the second medical image;
- wherein the navigation pathway corresponds to the modified structural orientation of the one or more objects in the second medical image.
A non-transitory computer implemented storage medium that stores machine-readable instructions executable by at least one processor determining a navigation pathway for navigating an invasive medical instrument inside a blood vessel, the machine-readable instructions comprising:
- receiving a first medical image associated with a patient, the first medical image acquired during a first medical imaging procedure;
- determining one or more parameters associated with the first medical image;
- identifying a second medical image from a plurality of images associated with the patient based on the determined one or more parameters, the second medical image acquired during a second medical imaging procedure prior to the first medical imaging procedure;
- determining deviation between a structural orientation of one or more objects in the first medical image and one or more objects in the second medical image;
- modifying the second medical image based on deviation between the structural orientation of the one or more objects in the first medical image and the one or more objects in the second medical image;
- and
- determining the navigation pathway for navigating the invasive medical instrument inside the blood vessel using the second medical image;
- wherein the navigation pathway corresponds to the modified structural orientation of the one or more objects in the second medical image.
