The implementation of hybrid conjugate gradient method in electromagnetic tomography / Michelle Ubong Sari

Electromagnetic tomography (EMT) is a type of electrical tomography based on electromagnetic induction. Reconstructing images with EMT involves solving inverse problems, which are often poorly defined due to limited prior information about imaging features. Optimization methods such as conjugate gra...
