MEDO ARIA

MEDO ARIA is a software medical device that employs machine learning to analyze and quantify DICOM ultrasound images, specifically for aiding in the diagnosis of developmental dysplasia of the hip in infants up to 12 months old. Its methodology centers on cloud-based processing offering semi-automatic landmarking, critical measurements like alpha angle and acetabular coverage, Hip Graf classification, and automated report generation to streamline clinical assessment.

MEDO ARIA is a cloud-based, standalone software as a medical device (SaMD) designed to assist qualified medical professionals in the diagnosis of developmental dysplasia of the hip (DDH) in neonates and infants aged 0 to 12 months. Its primary purpose is to view and quantify ultrasound image data using machine learning techniques, thereby supporting the radiologist's workflow by facilitating the evaluation, quantification, and generation of specialized reports for pediatric hip images. The software processes imported DICOM ultrasound images, allowing users to upload, browse, view, and manipulate both 2D and 3D infant hip scans. Core methodologies include tools for 2D image visualization, slice and frame scrolling, manual and semi-automatic landmark placements for key anatomical points, and quantitative analysis including alpha angle and acetabular coverage measurements. Unique features highlighted are its Hip Graf classification capability and integrated report generation. The device's safety and performance were assessed through software verification and validation testing, adhering to IEC 62304 standards for medical device software.
