This article describes how to configure a MIRC storage service for clinical trials. It applies to the RSNA MIRC implementation, and it is intended for MIRC site administrators.

A MIRC storage service includes several components specifically oriented to clinical trials. These components, called services, work together to support a single trial. When a MIRC site must support multiple clinical trials, multiple storage services are installed, one for each trial. Generally, if one or more teaching file components are required on a site, they are supported by separate storage services.

The key services related to clinical trials are:

  • DICOM Import Service - a DICOM Storage SCP that receives DICOM objects (typically from modalities or PACS) using the DICOM protocol.
  • HTTP Import Service - a service that receives DICOM, XML, or Zip objects (typically from remotely located imaging centers) using the HTTP or HTTPS protocol.
  • DICOM Export Service - a DICOM Storage SCU that forwards DICOM objects received by the HTTP Import Service to DICOM Storage SCPs using the DICOM protocol.
  • HTTP Export Service - a service that forwards DICOM objects received by the DICOM Import Service to HTTP Export Services (typically at other locations).
  • Database Export Service - a service that forwards DICOM, XML, Zip, or file objects to an interface to an external database, allowing athe construction of a trial-specific database outside the scope of MIRC.

For historical reasons, these are called the DICOM Service, even though they support more than DICOM objects.

To facilitate the management of a multi-site trial, MIRC also includes the Update Service - a service that provides the clinical trial administrator control over the software and configuration files at remotely located imaging centers.

The RSNA MIRC project has developed several supporting applications and tools that cooperate in the operation of a trial. The most important of these is the FieldCenter application, which runs at a remotely located imaging center and automatically transmits images to the principal investigator site.

1 Overview

The overall layout of the components in a MIRC site is shown in this diagram (to open it in a separate window, hold down the Shift key while clicking the link).

In a typical trial, the principal investigator's site will be a MIRC site and each of the imaging centers will run the FieldCenter application.
