Abstract
A system and method for generating a patient-specific anatomical atlas, e.g., includes, for each patient of a patient population: obtaining a respective anatomical atlas, and registering, by a computer processor, the respective anatomical atlas to an anatomical image of a current patient to obtain a respective registered anatomical atlas, and further includes, determining, by the processor, an average of the registered anatomical atlases.
Claims23
A system for generating an anatomical atlas, the system comprising:
- a computer processor configured to:
- using a common anatomical atlas for a plurality of patients of a patient population, perform a respective registration of the common anatomical atlas for each of the plurality of patients of the patient population to obtain a respective patient-population anatomical atlas;
- register each of the respective patient-population anatomical atlases to an anatomical image of a current patient to obtain a respective patient-specific anatomical atlas;
- and
- determine an average of the patient-specific anatomical atlases to obtain an average patient-specific anatomical atlas.
A computer-implemented method for generating an anatomical atlas, the method comprising:
- using a common anatomical atlas for a plurality of patients of a patient population, performing, by a computer processor, a respective registration of the common anatomical atlas for each of the plurality of patients of the patient population to obtain a respective patient-population anatomical atlas;
- registering, by the processor, each of the respective patient-population anatomical atlases to an anatomical image of a current patient to obtain a respective patient-specific anatomical atlas;
- and
- determining, by the processor, an average of the patient-specific anatomical atlases to obtain an average patient-specific anatomical atlas.
A non-transitory computer-readable medium on which are stored instructions that are executable by a processor, the instructions which, when executed by the processor, cause the processor to perform a method for generating an anatomical atlas, the method comprising:
- using a common anatomical atlas for a plurality of patients of a patient population, performing a respective registration of the common anatomical atlas for each of the plurality of patients of the patient population to obtain a respective patient-population anatomical atlas;
- registering each of the respective patient-population anatomical atlases to an anatomical image of a current patient to obtain a respective patient-specific anatomical atlas;
- and
- determining an average of the patient-specific anatomical atlases to obtain an average patient-specific anatomical atlas.
The system of 21, wherein the registering of the patient-population anatomical atlases further includes a non-linear scaling at different distances from a landmark registered in the anatomical image of the current patient.
