The medical imaging field continuously evolves with new technologies enhancing the efficiency and accuracy of diagnoses. In this blog post, we’ll explore innovative tools that are revolutionizing medical imaging: NVIDIA Holoscan, MONAI, OHIF, Orthanc, DICOMweb, Plastimatch, and PACS.

PACS: Picture Archiving and Communication System

A Picture Archiving and Communication System (PACS) is a medical imaging technology that provides economical storage and convenient access to images from multiple modalities. PACS digitizes and transmits images and reports, eliminating the need for manual film handling. PACS uses the DICOM standard for image storage and transfer and can incorporate non-image data like PDFs encapsulated in DICOM.

PACS comprises four major components:

Imaging Modalities: Such as X-ray, CT, and MRI.
Secured Network: For transmitting patient information.
Workstations: For interpreting and reviewing images.
Archives: For storing and retrieving images and reports.

With emerging web technologies, PACS offers timely and efficient access to images and related data, reducing the barriers associated with traditional film-based systems.

DICOMweb: Web-Based Medical Imaging Standard

DICOMweb™ is a set of RESTful services that form the DICOM standard for web-based medical imaging. It empowers web developers to harness healthcare images using industry-standard toolsets. DICOMweb can be implemented directly or as a proxy to DIMSE services, providing modern web-based access to DICOM-enabled systems without requiring image-producing modalities to support DICOMweb natively.

Orthanc: A Lightweight DICOM Server

Orthanc is a free and open-source DICOM server that simplifies medical imaging for hospitals and researchers. Its lightweight design ensures seamless integration and functionality.

You can install Orthanc directly using apt:

sudo apt-get install orthanc orthanc-dicomweb -y

Alternatively, you can use Docker to set up Orthanc:

docker pull orthancteam/orthanc:24.6.1
docker run -p 4242:4242 -p 8042:8042 --rm --name orthanc jodogne/orthanc-plugins:1.12.4

For sample setups with Docker, visit the Orthanc setup samples repository.

OHIF: An Extensible Web Imaging Platform

The Open Health Imaging Foundation (OHIF) Viewer is an open-source, web-based platform designed for medical imaging. With its user-friendly interface and powerful framework, OHIF allows developers to build complex imaging applications effortlessly. Released under the MIT license, OHIF supports custom workflows and quick case reviews without any installation hassles.

Here’s how you can get started with OHIF using Docker:

docker pull ohif/app:v3.8.1
docker run -d -p 3000:80/tcp --name ohif-viewer ohif/app:v3.8.1

Plastimatch: High-Performance Image Computation Software

Plastimatch is an open-source software focused on high-performance volumetric registration of medical images like CT, MRI, and PET scans. It’s designed for medical image processing and radiation therapy applications. Note that Plastimatch currently supports Ubuntu 20.04, not Ubuntu 22.04.

You can install it using the following command:

sudo apt-get install plastimatch -y
