CSI-EPT: Towards Practical Implementation
The information of electrical properties of biological tissues within human body can be useful information for diagnosis, tissue characterization, hyperthermia treatment planning and MR safety control.
Contrast Source Inversion Electrical Properties Tomography (CSI-EPT) is an MR base imaging modality, which reconstructs the electrical properties of the object. However, this method has not been implemented in practice due to the following issues:
1) The exact transmit phase, which is a necessary input of regular CSI-EPT algorithm, is not available from MR acquisitions.
2) The incident field, another input of CSI-EPT reconstruction, cannot be measured directly.
3) The reconstruction loses sensitivity at those regions with low electrical fields.
4) The sufficiency of the two-dimensional configuration, which has been used in most published results as an approximation
