Review and Analysis on Medical Tomography Improvement

Abstract

Medical Tomography is a technique to identify the condition underneath body tissue. It relates to identifying the health condition or certain diagnosis affirmation. Medical tomography for diagnostic imaging has been used for over a century. However, tremendous advances due to some limitations of existing medical tomography have been significantly growing in recent 30 years. MRI (Magnetic Resonance Imaging), CT-Scan extended to PET and SPECT, Ultrasound Imaging and Optical Imaging are the established modalities in medical diagnosis imaging. Radiation effect, high cost, speed, poor tissues penetration with low imaging resolution, are some issues on the established ones. This paper discusses the reviews of modern medical tomography improvement to cope with the existing diagnostic medical imaging limitation based on literatures. The review focuses on two points of views: the sensing modality or data acquisition and image reconstruction method innovation. Those two components are complimentary to each other. Less measurement will normally shift the load of producing good quality of reconstructed images to its image reconstruction algorithm. Hence comprehensive discussion on those two points of view is done. The main intention of the presented medical tomography – innovations is to improve the patient’s comfort and safety, effective data acquisition process, simpler device and maintaining good quality on the reconstructed medical images. In addition, this paper also presents open research opportunities derived from the mapping analysis.
