APPARATUS AND METHOD FOR VISUALIZATION

摘要

Based on heart behavior data, a computation unit determines a first time step at which a heart exhibits a first behavior in response to a first wave of an electrical signal, as well as a second time step at which the heart exhibits a second behavior in response to a second wave of the same. The computation unit reproduces the heart's behavior over time by updating a three-dimensional model of the heart according to the heart behavior data, simultaneously with variations in electrical signal strength over time according to electrocardiogram data. The computation unit coordinates this reproduction such that a first shape of the heart at the first time is reproduced step simultaneously with the first wave of the electrical signal, and such that a second shape of the heart at the second time step is reproduced simultaneously with the second wave of the electrical signal.

a memory configured to store a three-dimensional model of a heart of a patient, heart behavior data representing shapes of the heart at different time steps of a behavioral simulation of the heart, and electrocardiogram data representing temporal variations of an electrical signal in myocardium that have been measured from the patient; and a processor configured to perform a procedure including: determining, based on the heart behavior data, a first time step at which the heart exhibits a first behavior in response to a first wave of the electrical signal, as well as a second time step at which the heart exhibits a second behavior in response to a second wave of the electrical signal, and reproducing behavior of the heart over time by updating the three-dimensional model according to the heart behavior data, simultaneously with variations in strength of the electrical signal over time according to the electrocardiogram data, such that a first shape of the heart at the first time step is reproduced simultaneously with the first wave of the electrical signal, and such that a second shape of the heart at the second time step is reproduced simultaneously with the second wave of the electrical signal.
