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 for Cardiovascular System V: CT

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

Background:

Efforts to reduce radiation dose in computed tomography (CT) while maintaining image quality are ongoing.
Iterative reconstruction and noise reduction algorithms are established techniques.

Purpose of the Study:

To address the lack of standardized benchmarks and inconsistencies in experimental designs for deep learning-based CT denoising methods.
To improve the verifiability and reproducibility of research in this field.

Main Methods:

A standardized benchmark setup was developed for evaluating deep learning denoising algorithms.
A comprehensive and fair evaluation of state-of-the-art methods was performed using the proposed setup.

Main Results:

Most deep learning-based denoising methods demonstrated statistically similar performance.
Improvements in performance over recent years were found to be marginal.

Conclusions:

A need for more rigorous and fair evaluation of deep learning methods for low-dose CT image denoising is highlighted.
The proposed benchmark setup serves as a foundational tool for future research and algorithm evaluation.
