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

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...

Reconstruction of Signal using Interpolation

Reconstruction of Signal using Interpolation

Signal processing techniques are essential for accurately converting continuous signals to digital formats and vice versa. When a continuous signal is sampled with a period T, the resulting sampled signal exhibits replicas of the original spectrum in the frequency domain, spaced at intervals equal to the sampling frequency. To handle this sampled signal, a zero-order hold method can be applied, which creates a piecewise constant signal by retaining each sample's value until the next sampling...

Area of Science:

Medical Imaging
Image Reconstruction
Computational Imaging

Context:

Metal artifacts significantly degrade Computed Tomography (CT) image quality.
Existing interpolation methods are often insufficient for artifact reduction.
Clinical demand for artifact-free CT images remains high.

Purpose:

To develop an effective method for reducing metal artifacts in CT images.
To combine quartic polynomial and linear interpolation techniques for enhanced artifact removal.
To improve the diagnostic accuracy of CT scans with metal implants.

Summary:

A hybrid interpolation approach is proposed, utilizing quartic polynomial interpolation for initial image reconstruction of metal implants.
Linear interpolation is subsequently applied to eliminate residual streaks caused by artifacts.
The combined method's effectiveness is demonstrated through weighted application of both interpolation techniques.

Impact:

The proposed method offers improved CT image quality in the presence of metal implants.
Enhanced artifact reduction can lead to more accurate diagnoses and treatment planning.
This technique has the potential to broaden the clinical applications of CT imaging.
