FIELD PARADIGM FOR 3D
MEDICAL IMAGING:
Safer, More Accurate, and Faster SPECT, MRI, and MEG.
The approach of computational back-propagation of a field in Field Paradigm contrasts with the approach of current SPECT imaging methods that rely on the back-projection of a forward projection (e.g. Radon Transform) of the emission source density function. This reliance on the back-projection theory (e.g. Filtered Back-Projection) imposes the use of severe collimation of gamma radiation from a patient’s body. Consequently, over 99% of information carrying photons are blocked and wasted instead of being measured and exploited in the current SPECT machines. In comparison, SPECT based on Field Paradigm can exploit much more photons and reduce the dosage of radio-pharmaceuticals by 70% or more.
In the current MRI and MEG devices, information in the field variation along different radial distances and directions has not been exploited. Instead, current MRI machines employ frequency and phase encoding techniques for spatial localization of source elements that make the imaging process very slow (about 15 minutes). New MRI machines that incorporate Field Paradigm can reduce the imaging time by 70% or more. Field paradigm can also speed up ultra low-field (comparable to earth’s magnetic field) MRI by 70% or more. There is a possibility that MRI could be made as fast as X-ray computed tomography. In this case, harmless MRI could replace carcinogenic X-rays in soft-tissue imaging.
In the current MEG devices, due to the absence of the overlooked information, the problem of reconstructing the neural current density map has been misdiagnosed to be under-constrained and therefore unsolvable. Hence crude solutions based on heuristic assumptions of smoothness are being provided. New MEG machines based on Field Paradigm can provide a closed-form solution to the problem. This could lead to major advances in the early diagnosis, prevention, and treatment of brain related illnesses, as well as understanding thought processes, and direct brain to computer communication. Improvements similar to MEG are possible in Magnetocardiography (MCG). Improvements are also likely in limited view and localized tomography and Magnetic Resonance Spectroscopy (MRS). Field Paradigm can also bring marginal improvements to X-ray, ultra-sound, and diffusion optical tomography.
There is now sufficient information on Field Paradigm in the public domain (e.g. US Patent No. 8008625, and US Patent Application No. 12/658001) for experts to refute the claims here or develop it further.
