Computed Tomography

Computed Tomography

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Imaging Studies I: CT and MRI

Introduction: MRI and CT scans are crucial advancements in medical imaging techniques, playing a vital role in diagnosing conditions related to the gastrointestinal (GI) system. Each scan serves distinct purposes, targets specific areas, and requires unique nursing duties.
Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...

Background:

Imaging systems face a trade-off between spatial and temporal resolution due to hardware constraints.
Achieving high spatiotemporal resolution simultaneously is a significant challenge in modern imaging.

Purpose of the Study:

To propose a spatiotemporal compressive imaging (STCI) system for reconstructing high-spatiotemporal-resolution images.
To develop a novel reconstruction network capable of handling multiple compression ratios (CR).

Main Methods:

Development of a novel spatiotemporal compressive imaging (STCI) system.
Design of a specialized reconstruction neural network for varying compression ratios.
Validation through both simulation and optical experiments.

Main Results:

The STCI system successfully reconstructed high-spatiotemporal-resolution images across nine different compression ratios.
High reconstruction accuracy of 28.28 dB was achieved with a maximum spatiotemporal CR of 128:1.
The method demonstrated effectiveness in overcoming the inherent resolution limitations.

Conclusions:

The proposed STCI system effectively reconstructs high-spatiotemporal-resolution images from low-resolution measurements.
The novel reconstruction network supports multiple compression ratios, enhancing system flexibility.
The findings present a viable solution for advanced imaging applications requiring high resolution.
