Pseudo-Computed Tomography (PCT): Revolutionizing Imaging with Non-Ionizing Modalities

Abstract

Pseudo-Computed Tomography (PCT) is an innovative imaging technique designed to simulate the high-resolution, cross- sectional images generated by traditional Computed Tomography (CT), without the associated risks of ionizing radiation. By integrating data from non-ionizing imaging modalities such as Magnetic Resonance Imaging (MRI), ultrasound, and other advanced imaging systems, PCT produces images that closely resemble those of conventional CT scans. This non-invasive technique holds considerable promise for medical diagnostics, treatment planning, and radiation-free imaging, particularly in radiation-sensitive settings. This review provides a comprehensive examination of the methodologies behind PCT, its current applications, the challenges it faces, and its future potential in advancing imaging technologies, especially in environments where minimizing radiation exposure is critical.
