Abstract

Systems and methods are disclosed herein for anatomical modeling using information obtained during a medical procedure, whereby an initial anatomical model is generated or obtained, a correspondence is determined between the initial model and additional data and/or measurements from an invasive or noninvasive procedure, and, if a discrepancy is found between the initial model and the additional data, the anatomical model is updated to incorporate the additional data and reduce the discrepancy.

Claims (47)

1. A method of automatically updating an anatomical model, comprising:

using a processor to determine a correspondence between patient-specific data and at least one of a patient-specific three-dimensional anatomical model or at least one characteristic associated with the three-dimensional anatomical model;

using the processor to identify a discrepancy between the patient-specific data and at least one of the three-dimensional anatomical model or the at least one associated characteristic;

using the processor to modify at least one of the three-dimensional anatomical model or the at least one associated characteristic to reduce the discrepancy;

using the processor to generate at least one recommendation of an intervention on the patient based on at least one of the three-dimensional anatomical model or the at least one associated characteristic; and

using the processor to transmit the at least one recommendation to a display unit.

2. The method of claim 1 , further comprising:

using the processor to model an intervention or a part thereof on the anatomical model; and

using the processor to transmit a representation of the modeled intervention or part thereof to the display unit.

3. The method of claim 2 , wherein the intervention includes one or more of: an insertion of an endoscopic device, a laparoscopic device, a stent, a prosthetic implant, a graft, or a needle; a bypass grafting procedure; a rotablation; an atherectomy; an angioplasty; an endarterectomy; a percutaneous coronary intervention;

a carotid intervention; a peripheral intervention; a renal revascularization; a mesenteric revascularization; or an arteriovenous access procedure.

4. The method of claim 1 , wherein the patient-specific data is from a medical procedure and the medical procedure is an invasive procedure.

5. The method of claim 1 , wherein the patient-specific data is from a medical procedure and the medical procedure is a diagnostic procedure.

6. The method of claim 1 , wherein the at least one associated characteristic is a blood flow characteristic, a location of one or more lesions or blockages, or a location of one or more interventional devices.

7. The method of claim 1 , wherein the patient-specific data includes at least one of: data from an angiogram; data from optical coherence tomography; data from an intravenous ultrasound; blood pressure data; coronary flow data; cardiac contractility data; a measurement of a plaque; a local heart viability; data showing whether an occlusion is total or subtotal; data relating to the patient's physiological state; data relating to myocardial wall motions; stent position data; or data from a percutaneous coronary intervention.

8. The method of claim 1 , wherein using the processor to determine a correspondence between the patient-specific data and at least one of the three-dimensional anatomical model or the at least one associated characteristic comprises using the processor to determine a location of the anatomical model to which the patient-specific data may apply.

9. The method of claim 1 , wherein the display unit is located in a medical facility.

10. A computer-implemented method for automatically updating an anatomical model, the method comprising:

using a processor to determine a correspondence between patient-specific data and at least one of a patient-specific three-dimensional anatomical model or at least one characteristic associated with the three-dimensional anatomical model;

using the processor to locate a discrepancy between the patient-specific data and at least one of the anatomical model or the at least one associated characteristic;

updating, using the processor, at least one of the anatomical model or the at least one associated characteristic to reduce the discrepancy;

using the processor to generate at least one recommendation of an intervention on the patient based on at least one of the three-dimensional anatomical model or the at least one associated characteristic; and

using the processor to transmit the at least one recommendation to a display unit.

11. The method of claim 10 , wherein the at least one associated characteristic is a blood flow characteristic.

12. The method of claim 10 , further comprising:

using the processor to model the intervention on the anatomical model; and

using the processor to transmit a representation of the modeled intervention to the display unit.

13. The method of claim 10 , wherein the patient-specific data is from an interventional procedure, and the method further comprising:

periodically receiving, at the processor, refreshed patient-specific data from the interventional procedure;

using the processor to monitor for a new discrepancy between the refreshed patient-specific data and at least one of the anatomical model or the at least one associated characteristic; and

if a new discrepancy is found:

updating, using the processor, at least one of the anatomical model or the at least one associated characteristic to reduce the new discrepancy.

14. An anatomical modeling system comprising a processor, wherein the processor is configured to:

determine a correspondence between patient-specific data and at least one of a patient-specific three-dimensional anatomical model or at least one characteristic associated with the three-dimensional anatomical model;

identify a discrepancy between the patient-specific data and at least one of the three-dimensional anatomical model or the at least one associated characteristic;

modify at least one of the three-dimensional anatomical model or the at least one associated characteristic to reduce the discrepancy;

generate at least one recommendation of an intervention on the patient based on at least one of the three-dimensional anatomical model or the at least one associated characteristic; and

transmit the at least one recommendation to a display unit.

15. The system of claim 14 , wherein the patient-specific data is from an interventional procedure, and the processor is further configured to:

periodically receive refreshed patient-specific data from the interventional procedure;

monitor for a new discrepancy between the refreshed patient-specific data and at least one of the three-dimensional anatomical model or the at least one associated characteristic; and

if a new discrepancy is found:

update at least one of the three-dimensional anatomical model or the at least one associated characteristic to reduce the new discrepancy.

16. The system of claim 14 , wherein the at least one associated characteristic is a blood flow characteristic.

17. The system of claim 15 , wherein the processor is further configured to:

generate a model of the intervention on the anatomical model; and

transmit a representation of the modeled intervention to the display unit.
