Introduction

Medical imaging, such as X-ray, MRI, and ultrasound are used noninvasively to diagnose and monitor a wide range of health conditions, spanning oncology, trauma, stroke and more inside patients. As medical images are getting better, healthcare organizations need affordable and flexible storage solutions for storing huge amounts of imaging data. Radiologists are seeking innovative technologies to boost their productivity, and AI is becoming more prevalent in simplifying complex tasks and reducing mistakes in their workflows.

Challenges

The healthcare system is struggling to meet the growing demand for medical imaging procedures.

  1. Scalable Storage and Analysis: Medical imaging generates a vast amount of data, including high-resolution images such as X-rays, MRIs, CT scans, and ultrasounds. Managing and analyzing this massive volume of data can be challenging, especially with traditional on-premises storage solutions.
  2. Performance and Accessibility: Accessing medical images quickly and efficiently is crucial in clinical settings. Physicians and healthcare professionals require rapid retrieval and viewing of patient images to make timely and accurate decisions.
  3. Developer-Friendly Metadata: Medical imaging data is typically stored in a format called DICOM (Digital Imaging and Communications in Medicine), which uses complex group and element hexadecimal numbers to represent metadata attributes.
  4. High-Speed Image Decoding: Decoding medical images can be computationally intensive, especially for large data sets.
  5. Efficient Image Loading and Compression: Efficiently loading medical images for viewing and analysis is essential to minimize response times and provide a smooth user experience.
  6. Scalability and Historical Data Ingestion: As medical imaging data continues to grow over time, the system needs to scale to handle the increasing workload
  7. Secure Data Sharing and Privacy Compliance: Medical imaging data contains sensitive patient information that must be protected to comply with privacy regulations like HIPAA.
  8. Comprehensive Logging for Accountability: Challenges exists in logging mechanism to ensures transparency in data access and usage, enabling organizations to review and monitor data interactions for compliance and security purposes.
  9. Cost Management: Medical imaging equipment and storage infrastructure can be costly to procure, maintain, and upgrade. Moreover, the storage and processing requirements increase as more patients’ imaging data is collected over time.

AWS HealthImaging service aims to address all these challenges and provide a comprehensive solution for efficient, cost-effective, secure medical imaging data management, enabling healthcare organizations to deliver quality patient care and foster advancements in research and clinical practice.

AWS HealthImaging

AWS HealthImaging offers a purpose-built medical imaging data store to help doctors, hospitals, and researchers speed up their work, make the most of imaging data, develop personalized treatments, save money and simplify infrastructure setup, allowing healthcare providers more time to focus on patient care and research.

With HealthImaging, all applications within the organization can access a single authoritative copy of data without duplication, and users can securely access this data from any location.

By using the user-friendly HealthImaging console, provisioning a data store capable of hosting petabytes of medical imaging data becomes effortless, ensuring every image is readily available for low-latency retrieval. Moreover, HealthImaging reduces the need for extensive infrastructure to run enterprise imaging solutions, resulting in cost savings and reduced operational complexity.

Customers leveraging HealthImaging’s applications benefit from cost-effective storage for image archives, free from concerns about hardware refresh cycles or capacity planning.

As new imaging data is generated, it can be seamlessly imported into HealthImaging, instantly available for retrieval by diagnostic applications like PACS. AWS DataSync, AWS Direct Connect, and purpose-built gateways from AWS partners simplify the process of moving data from edge locations to the cloud.

HealthImaging is a cutting-edge HIPAA-eligible service enables to securely store, analyze, and share vast amounts of medical imaging data at a petabyte scale in the cloud.

Scalability is a hallmark of HealthImaging, made possible through modern cloud-native technologies that enable parallel ingestion of multiple DICOM studies. It fully embraces DICOM, the globally recognized standard for the communication and management of medical imaging information.

Historical archives can be quickly ingested without disrupting clinical workloads for new data, ensuring seamless scalability as the imaging needs grow.

By leveraging a single copy of patient imaging data in the cloud and thanks to subsecond image retrieval latencies for both active and archive data, Healthimaging service enables to achieve significant cost saving efficiency without compromising performance at the point-of-care.

HealthImaging leverages High-Throughput JPEG 2000 (HTJ2K), an advanced codec optimized for medical imaging, to ensure lightning-fast image decoding. By utilizing single instruction multiple data (SIMD) instructions on modern processors, HTJ2K delivers unmatched performance — decoding images significantly faster than JPEG 2000 and all other DICOM transfer syntaxes. Even zero-footprint web viewers benefit from this extreme speed through the use of WASM SIMD.

The service sets new industry standards in image loading performance, achieved through efficient metadata encoding, lossless compression, and progressive resolution data access. This enables image viewers and AI algorithms to comprehend DICOM studies without the need to load the entire image data, resulting in lightning-fast loading times without compromising image quality.

Benefits

HealthImaging simplifies application development by returning DICOM metadata in a more user-friendly format, using human-readable keywords instead of intricate hexadecimal numbers.

HealthImaging ensures efficient creation of de-identified image copies, eliminating the duplication of pixel data and effectively lowering storage expenses. The service employs access control at the metadata level, allowing specific attributes of each image, like patient ID and modality, to be accessed based on customer-configured permissions. This safeguarding mechanism ensures secure data sharing without compromising sensitive information.

For example, a cloud-based Picture Archiving and Communication System (PACS) equipped with decision support software can access the same data copy utilized for disaster recovery, ensuring uninterrupted continuity of care. Simultaneously, researchers collaborating on academic projects can access the precise image copy required for their investigations.

HealthImaging’s adaptability enhances data accessibility and promotes seamless collaboration among diverse stakeholders, driving advancements in both clinical practice and research endeavors.

Cloud-based services like HealthImaging offer scalable storage options that can accommodate the ever-growing volume of medical images while providing the necessary computing power for efficient analysis.

HealthImaging addresses performance and accessibility challenge by providing subsecond image retrieval latencies, ensuring that medical images are available with minimal delays, even for large-scale data sets.

Efficient Image Loading and Compression: HealthImaging employs lossless compression and progressive resolution data access to ensure images load quickly without compromising quality.

HealthImaging utilizes modern cloud-native technologies to enable parallel ingestion of multiple DICOM studies, ensuring seamless scalability as imaging needs expand. Additionally, it facilitates the quick ingestion of historical archives without affecting ongoing clinical workloads.

Data Privacy

With HealthImaging, sensitive medical imaging data remains protected and accessible only to authorized parties, promoting confidentiality and adherence to regulatory requirements.

HealthImaging employs robust access control at the metadata level, guaranteeing that users and applications can only access the specific images and metadata fields relevant to their roles. This stringent measure effectively prevents the unauthorized dissemination of patient protected health information, ensuring data security and compliance.

To further bolster security, all interactions with HealthImaging APIs are meticulously logged and recorded in AWS CloudTrail. This comprehensive logging mechanism allows for detailed review and audit trails, facilitating accountability and transparency in data access and usage.
