Image Quality Assessment Framework - PLAX Rotation/Orientation

Project Description

-
-

Image rotation can significantly affect the quality and interpretability of PLAX echocardiographic images. This project aims to create a standardized, open-access dataset of PLAX images with varying degrees of rotation, along with expert annotations. -

We are training an AI to automatically detect and quantify the degree of incorrect rotation in left ventricular (LV) images within the parasternal long axis (PLAX) view. To achieve this, we are ranking images based on the degree of rotation, from the most clockwise to the most anticlockwise. In some cases, the degree of rotation between two images may be minimal, making their exact order less critical. However, it is essential to ensure that images with significant differences in rotation are ranked accurately. Proper ranking will help the AI model better understand and quantify rotation discrepancies, contributing to improved diagnostic precision. +

Project Goals

-
    -
  • Develop a Reference Dataset: Create a comprehensive dataset of PLAX echocardiographic images with diverse rotation angles, carefully annotated by experienced echocardiographers.
    • -
  • Standardize Rotation Assessment: Establish clear and objective criteria for assessing the degree of rotation in PLAX images.
    • -
  • Empower AI Development: Provide a high-quality dataset to train and validate AI algorithms for automatic rotation detection and correction.
    • -
  • Improve Image Acquisition: Develop training materials and guidelines to help sonographers optimize image acquisition and minimize rotational artifacts.
    • -
  • Enhance Diagnostic Accuracy: Ultimately improve the accuracy and reliability of PLAX echocardiographic interpretations for better patient care.
