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

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...

Scanning Electron Microscopy

Scanning Electron Microscopy

A scanning electron microscope (SEM) is used to study the surface features of a sample by using an electron beam that scans the sample surface in a two-dimensional manner. Typically, areas between ~1 centimeter to 5 micrometers in width can be imaged. SEM can be used to image bacteria, viruses, tissues as well as larger samples like insects. Conventional SEM gives a magnification ranging from 20X to 30,000X and spatial resolution of 50 to 100 nanometers.

Area of Science:

Medical Imaging
Radiology
Diagnostic Imaging Technology

Background:

Helical scanning in computed tomography (CT) results in partial volume artifacts due to increased slice thickness.
Slice thickness in helical CT is influenced by radiation fan thickness and patient translation speed.

Purpose of the Study:

To introduce and evaluate a novel method, moving beam helical scanning (MBHS), for reducing partial volume artifacts in CT imaging.
To compare the image quality of MBHS with conventional CT and conventional helical scanning.

Main Methods:

MBHS utilizes a rotatable collimator between the X-ray source and patient to focus the radiation fan on a fixed point.
The collimator is repositioned between slices to maintain image quality.
Performance was assessed by scanning wires and phantoms on a modified CT scanner.

Main Results:

MBHS demonstrated a slice profile with full-width-at-tenth-maximum at iso-center identical to conventional CT.
Conventional helical scanning showed a 59% increase in the full-width-at-tenth-maximum compared to conventional CT.
MBHS significantly reduced partial volume artifacts compared to conventional helical scanning.

Conclusions:

MBHS offers a solution to mitigate partial volume artifacts inherent in helical CT scanning.
The method enables the acquisition speed benefits of helical scanning with image quality comparable to conventional CT.
MBHS represents a significant advancement in CT imaging technology for improved diagnostic accuracy.
