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 III: Computed Tomography

DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...

Summary

A new mouth-fitted aligner accurately positions patients for small field of view (FOV) cone beam CT (CBCT) scans. This device reduces radiation dose by eliminating the need for scout images during dental CBCT procedures.

Area of Science:

Dental Imaging
Radiological Technology

Background:

Optimizing positioning and field of view (FOV) size in cone beam CT (CBCT) is crucial for accurate dental diagnostics.
Small FOVs are challenging for precise patient positioning, potentially increasing radiation exposure.
Current methods often rely on scout images, which contribute to patient radiation dose.

Purpose of the Study:

To evaluate a novel external alignment device for optimizing FOV positioning and size in CBCT.
To train radiographers in accurate patient positioning for small FOV CBCT scans.
To reduce patient radiation dose by minimizing or eliminating the need for scout imaging.

Main Methods:

A practical external alignment device was designed for intraoral fitting.
Test objects were used to validate the aligner's design and geometry.
An in vivo study compared patient positioning accuracy using the aligner versus traditional scout images for small FOV (4-8 cm diameter/height) dental CBCT scans on Accuitomo F170 and iCAT Next Gen scanners.

Main Results:

The aligner demonstrated correct design and geometry for superimposing scanner and volume of interest axes.
No significant difference in patient positioning accuracy was found when using the aligner compared to scout images.
The aligner effectively facilitated patient positioning for small FOV dental CBCT.

Conclusions:

The external alignment device is a reliable tool for patient positioning in small volume CBCT scans.
Utilizing this aligner can spare patients the radiation dose associated with conventional scout imaging.
The device aids in training radiographers for precise CBCT positioning, enhancing efficiency and safety.
