Abstract
A method and apparatus for simulating a medical procedure to be performed on a patient. Patient-specific data that is specific to the patient on whom the medical procedure is to be performed is received. A generic model is modified using the patient-specific data to generate a hybrid simulation model that is customized to the patient. A simulation of the medical procedure is performed using the hybrid simulation model and dynamic simulation information corresponding to at least one of the medical procedure or the patient. The simulation is customized to both the patient and the medical procedure.
Claims27
A method for simulating a medical procedure to be performed on a patient, the method comprising:
- receiving patient-specific data that is specific to the patient on whom the medical procedure is to be performed;
- modifying a generic model using the patient-specific data to generate a hybrid simulation model that is customized to the patient;
- and
- performing a simulation of the medical procedure prior to the medical procedure using the hybrid simulation model and dynamic simulation information, wherein the dynamic simulation information includes information about one or more parameters expected to change during the medical procedure and corresponds to at least one of the medical procedure or the patient, wherein the simulation is customized to both the patient and the medical procedure,
- wherein performing the simulation comprises:
- simulating, dynamically, the medical procedure using the hybrid simulation model and the dynamic simulation information such that a patient anatomy of the patient is represented with a gradient of levels of fidelity, wherein a level of fidelity of anatomical structures in the hybrid simulation model decreases during the simulation as a distance from a surgical path of the medical procedure increases.
A simulation system comprising:
- a processor configured to:
- receive patient-specific data that is specific to a patient on whom a medical procedure is to be performed;
- modify a generic model using the patient-specific data to generate a hybrid simulation model that is customized to the patient;
- and
- perform a simulation of the medical procedure prior to the medical procedure using the hybrid simulation model and dynamic simulation information, wherein the dynamic simulation information includes information about one or more parameters expected to change during the medical procedure and corresponds to at least one of the medical procedure or the patient, wherein the simulation is customized to both the patient and the medical procedure,
- wherein performing the simulation comprises:
- adjusting how one or more anatomical structures of a patient anatomy of the patient deform in response to changes to a pose of the patient during the simulation of the medical procedure.
A method for simulating a medical procedure to be performed on a patient, the method comprising:
- receiving anthropometric data and patient diagnostic data for the patient;
- selecting a generic model of a representative patient from a database system;
- modifying the generic model based on the anthropometric data and the patient diagnostic data to generate a hybrid simulation model that is customized to the patient;
- and
- performing a simulation of the medical procedure prior to the medical procedure using the hybrid simulation model and dynamic simulation information, wherein the dynamic simulation information includes information about one or more parameters expected to change during the medical procedure and corresponds to at least one of the medical procedure or the patient,
- wherein the simulation is customized to both the patient and the medical procedure,
- wherein the simulation accounts for effects of simulated interactions between anatomical structures of the patient and instruments used in the medical procedure,
- wherein the simulation dynamically adapts to each step of the medical procedure such that a portion of a patient anatomy of the patient that interacts with the medical procedure at the each step of the medical procedure is rendered at a higher level of fidelity, and
- wherein performing the simulation comprises:
- simulating, dynamically, the medical procedure using the hybrid simulation model and the dynamic simulation information such that a patient anatomy of the patient is represented with a gradient of levels of fidelity, wherein a level of fidelity of anatomical structures in the hybrid simulation model decreases during the simulation as a distance from a surgical path of the medical procedure increases.
