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...
Computed Tomography01:10

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...

Area of Science:

  • Medical Imaging
  • Radiology
  • Biomedical Engineering

Background:

  • Accurate segmentation of pelvic CT images is crucial for diagnosis.
  • Distinguishing bone tissue from regions with similar radiodensities, like hemorrhage, presents a challenge.

Purpose of the Study:

  • To introduce a hierarchical method for bone tissue recognition in pelvic CT images.
  • To enable differentiation between segmented objects with similar grey-level values, specifically bone and active hemorrhage.
  • To address challenges in bone segmentation, classification, and hemorrhage assessment.

Main Methods:

  • A hierarchical approach was developed for image analysis.
  • The method focuses on regions extracted from pelvic CT images.
  • It utilizes image processing techniques to differentiate tissues based on grey-level values.

Main Results:

  • The proposed method successfully distinguishes bone tissue from regions of active hemorrhage.
  • It effectively segments and classifies bone tissue.
  • The technique aids in assessing the presence of active hemorrhage.

Conclusions:

  • The hierarchical method offers an effective solution for bone tissue recognition in pelvic CT scans.
  • This approach enhances the accuracy of differentiating bone from hemorrhage.
  • It contributes to improved diagnostic accuracy in pelvic imaging analysis.
