Computed Tomography01:10

Computed Tomography

9.5K
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...

Radiological Investigation I: X-ray and CT

1.5K
Radiological investigations, including X-rays and computed tomography (CT) scans, are critical for diagnosing and evaluating various medical conditions. These imaging techniques provide valuable insights into the body's internal structures, aiding in the detection of abnormalities, assessment of disease progression, and development of treatment strategies. This article delves into two primary radiological investigations, chest X-rays and CT scans, outlining their purpose, procedures, and...

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...

Area of Science:

  • Medical Imaging
  • Radiology
  • Computational Imaging

Background:

  • X-ray scatter degrades image quality in breast CT.
  • Accurate scatter correction is crucial for improved diagnostic accuracy.
  • Previous scatter correction methods had limitations, including artifact introduction.

Purpose of the Study:

  • To further develop and implement an x-ray scatter correction method for dedicated breast CT.
  • To enable initial patient testing of the improved scatter correction algorithm.
  • To evaluate the impact of the enhanced algorithm on image quality and artifact reduction.

Main Methods:

  • Acquisition of a second set of breast CT projections with a perforated tungsten plate.
  • Implementation of a wirelessly controlled electronic positioner for the tungsten plate.
  • Algorithm improvements including automated exclusion of invalid points and a new scatter estimation method.
  • Evaluation using a breast phantom and nine patient images.

Main Results:

  • Avoidance of artifact introduction, particularly at object borders.
  • Improved contrast (signal difference and signal difference-to-noise ratio).
  • Enhanced contrast, better cupping correction, and more consistent voxel values in patient images.
  • Reduction of artifacts in reconstructions of non-regularly shaped breasts.

Conclusions:

  • The implemented hardware and software improvements allow reliable use of the scatter correction method in patient breast CT imaging.
  • The proposed method significantly improves image quality by reducing artifacts and enhancing contrast.
  • Further evaluation is needed to determine the clinical impact on detection and diagnosis.
