De-identification of medical records is crucial for unlocking valuable information for several reasons: Privacy, compliance, enabling medical research, and reducing the risk of data breaches. DICOM is a widely-used file format standard for exchanging medical images such as radiography, ultrasonography, computed tomography (CT), magnetic resonance imaging (MRI), and radiation therapy. Accurate anonymization of DICOM files presents unique challenges:

  • Sensitive information is often “burned” into the image, which requires computer vision or OCR to identify
  • Sensitive information is also stored in metadata fields, some of which include unstructured text
  • The DICOM standard is decades old, hence there are thousands of variants of file formats and metadata fields
  • Each DICOM file can contain thousands of images (slices), in different resolutions
  • Different image modalities (MRI vs. US vs. CT scans) have their own nuances
This session presents a scalable, enterprise-grade solution that provides high accuracy across supporting multiple image formats and clinical modalities. Join to see live demos & code that tackles these challenges with the help of John Snow Labs’ Visual NLP. We’ll will explore DICOM processing capabilities, from computing basic metrics on a potentially large dataset to de-identifying images and metadata. We will also discuss infrastructure and how to scale pipelines to handle heavy workloads.
