Imaging Studies for Cardiovascular System III: X-Ray

191
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...

Radiological Investigation I: X-ray and CT

246
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...

Area of Science:

  • Medical Imaging
  • Artificial Intelligence
  • Computational Biology

Background:

  • Effective COVID-19 screening is crucial for pandemic control.
  • Chest X-ray analysis is a key method for COVID-19 detection.
  • Deep learning models for X-ray analysis can suffer from overfitting and generalization issues.

Purpose of the Study:

  • To propose an ensemble deep learning model for enhanced COVID-19 detection using chest X-ray images.
  • To address limitations of single deep learning models, such as overfitting and high variance.
  • To improve the accuracy and reliability of automated COVID-19 screening.

Main Methods:

  • Developed EDL-COVID, an ensemble deep learning model combining multiple COVID-Net snapshot models.
  • Employed a weighted averaging ensembling technique sensitive to model performance across different classes.
  • Utilized chest X-ray images for training and validation of the proposed model.

Main Results:

  • EDL-COVID achieved a COVID-19 detection accuracy of 95%.
  • The proposed ensemble model demonstrated superior performance compared to the baseline COVID-Net model (93.3% accuracy).
  • Results indicate the effectiveness of ensemble learning in improving deep learning-based medical image analysis.

Conclusions:

  • Ensemble deep learning, specifically EDL-COVID, offers a promising approach for accurate COVID-19 detection from chest X-rays.
  • The weighted averaging ensembling method effectively mitigates issues associated with single deep learning models.
  • EDL-COVID provides a more robust and accurate tool for radiological screening of COVID-19 cases.
