Summary
C-arm Cone Beam CT (CBCT) enhances interventional procedures with cross-sectional imaging for planning and guidance. While offering benefits, its image quality and radiation dose quantification present current limitations.
Area of Science:
- Medical Imaging
- Interventional Radiology
Background:
- C-arm Cone Beam CT (CBCT) is increasingly integrated into angiography systems.
- This technology provides cross-sectional imaging, enabling new clinical applications.
Purpose of the Study:
- To review the technical aspects of CBCT.
- To explore current clinical applications and potential benefits of CBCT.
- To discuss limitations of CBCT technology.
Main Methods:
- Literature search conducted using PubMed.
- Search terms included "CBCT", "Cone Beam CT", and variations.
- Relevant articles were reviewed for inclusion.
Main Results:
- CBCT applications span vascular and non-vascular interventions.
- It aids in preprocedural planning, intraprocedural guidance, and postprocedural assessment.
- Benefits include improved safety and accuracy, but limitations in image quality and radiation dose quantification exist.
Conclusions:
- CBCT offers significant patient benefits in interventional suites despite limitations.
- The technology is evolving and poised to become integral to image-guided interventions.

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...

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...

The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
