Abstract
Exemplary embodiments of the present disclosure are directed to estimating an electrical property of tissue using MR images. Complex values having real components and imaginary components are generated and are associated with pixels in one or more MR images that corresponding to a region of tissue for which the electrical property is constant. An estimated value of the electrical property for the region of tissue is determined based on a least squared error estimation applied to the complex values.

A method of estimating an electrical property of tissue using MR images comprising:
- generating complex values having real components and imaginary components, the complex values being associated with pixels in one or more MR images corresponding to a region of interest;
- segmenting the region of interest into one or more sub-regions for which the electrical property is constant;
- and
- determining an estimated value of the electrical property for at least one of the one or more sub-regions based on a least squared error estimation applied to the complex values associated with the at least one of the one or more sub-regions.
A non-transitory computer readable medium storing instructions, wherein execution of the instruction by a processing device causes the processing device to implement a method for estimating electrical properties of tissue using MR images comprising:
- generating complex values having real components and imaginary components, the complex values being associated with pixels in one or more MR images corresponding to a region of interest;
- segmenting the region of interest into one or more sub-regions for which the electrical property is constant;
- and
- determining an estimated value of the electrical property for at least one of the one or more sub-regions based on a least squared error estimation applied to the complex values associated with the at least one of the one or more sub-regions.
A system for estimating electrical properties of tissue using MR images comprising:
- a non-transitory computing readable medium storing complex values having real components and imaginary components, the complex values being associated with pixels in one or more MR images corresponding to a region of interest;
- and
- a processing device programmed to segment the region of interest into one or more sub-regions for which electrical property is constant and determine an estimated value of the electrical property for at least one of the one or more sub-regions based on a least squared error estimation applied to the complex values associated with the at least one of the one or more sub-regions.
