Each participating facility has PACS infrastructure installed and operated on a day-to-day basis. The operation of the PACS is managed independently by each facility. When a patient is admitted to a facility for the first time, he/she should register his/her personal information. The patient credential is local, associated only with the facility where the registration occurs. This signifies that patient information can be different in other facilities. Every time a patient is examined at a facility, the imaging data acquired from the modality equipment will then be stored in the PACS archive storage installed in the respective facility. The mechanism for image data retrieval from the PACS storage can differ for each facility. A PACS solution in one facility, for example, provides image retrieval service via a non-DICOM standard interface and restricts DICOM Storage and Query/Retrieve services via DICOM networks. Therefore, it is important to address configurability and flexibility issues in the imaging gateway design so that it can be interfaced with a multitude of PACS solutions.
Network connectivity with the server applications of the PACS solutions installed in all facilities can only be established via a DICOM network interface. None of the PACS server applications provides an alternative interface, for example the web interface referred to as Web Access to DICOM Persistent Objects (WADO) has been specified in the DICOM standard. Having no alternative imaging data interface enforces heavyweight image retrieval by a display client since the image should be transported over the network in a DICOM file format. A binary in DICOM format can be large, on the order of megabytes, especially if it contains numerous image frames. This is problematic in the case of a slow network or when a preview of a multi-frame image is needed for display. Hence, it is also important for the imaging gateway to provide an interface that can be configured to be accessible from an external network, while ensuring the security of the image transfer and taking care of the performance aspect of the transferrable image payload.
Based on the workflow in Figure 2, we implemented the gateway as follows. The imaging document source is the gateway that intermediates the legacy PACS with HIE. It is capable of providing and registering imaging documents to the document repository to be included in the shared document listings in the HIE. When providing and registering the images to the document repository, it utilizes the RAD-68 transaction specification of the IHE-RAD TF. In this transaction, images are grouped into sets and only image manifests or references are registered to the document repository instead of the original DICOM images. Image manifests are embedded as an attachment to a SOAP request and then sent via HTTP to a SOAP Web service endpoint of the document repository that is responsible for receiving XDS document registration. The SOAP request body contains additional metadata whose format is specified in the RAD-68 transaction. Metadata values are populated by the imaging document source based on the content of the image manifest.
Figure 3 shows three samples of image sets taken from computed tomography (CT), computed radiography (CR), and ultrasound (US) modalities. The image sets correspond to abdomen studies with 22 images, colon studies with 50 images, and thyroid gland studies with 6 images, respectively. Samples are chosen from available population sets to represent variations in image sizes. For all images in each set, equivalent JPEG image caches are generated from the acquired DICOM files. By generating cache files, the gateway can immediately provide a representative image requested by the viewer without conducting image preprocessing every time. As seen in the figure, the JPEG caches are significantly smaller in size compared to the original DICOM files, thus enabling the viewer to display images in a timely manner. For CT images, the average JPEG-DICOM ratio is 7.42%, the minimum ratio is 7.15%, and the maximum ratio is 7.62%. CR images have an average JPEG-DICOM ratio of 4.4% with a minimum ratio of 3.73% and a maximum ratio of 5.94%. Finally, US images correspond to an average JPEG-DICOM ratio of 12.07%, a minimum ratio of 4.84%, and a maximum ratio of 13.51%. These ratios are specific to the sample images used in the tests and can vary for different examination images across different modalities.
DICOM Gateway is a middleware PACS/ DICOM system that makes sharing PACS/ DICOM images easy as it plays well with other existing PACS system. With DICOM gateway there is no need to VPN. DICOM gateway is built for Mac OSX. DICOM Gateway automated the creation of DICOM routing, distribution and manage its DICOM requests/ queries (traffic) securely with HIPAA-complaint security optimization. It's a lightweight app built about 5.6 MB.
The Model DR72 Router provides the capability to move images from remote sites into a DICOM workstation, archive or PACS system at a central location. At the remote sites, images can be acquired with low cost teleradiology system components and transmitted over Broadband Internet network connections. Systems can be configured to receive from multiple sites simultaneously. Patient demographic data entry is fully configurable to meet requirements of the archive or PACS system. Received images can be redirected to one or more DICOM destinations as required. The DR72 Router component is also available on all Images-on-Call Film DigitizerStations providing DICOM output capability.
Using 256-bit AES encryption and data compression, our DICOM gateways allow unsurpassed resource-efficient and reliable forwarding of medical grade images even in low-bandwidth environments without the need for VPN, P2P connections, or heavy IT infrastructure support.
LifeSys Education overcomes the physical limitations of a traditional onsite radiology residency program by switching key aspects of learning online, without needing to invest heavily in hardware or infrastructure. The platform allows students to view full DICOM images remotely and practice writing reports, under the complete guidance and supervision of trainers, aided by a built-in decision support system specifically designed to improve diagnostic reporting competency.

From its inception in 1986, DeJarnette Research Systems, Inc. has been known for technical innovation. In its early years, the company was among the industry leaders in driving standards, such as ACR-NEMA, DICOM, and HL7. Before the advent of DICOM, DeJarnette designed, developed, and manufactured its high performance, robust, and widely used ACR-NEMA Medical Network Gateway known as ImageShare 910. Our SureNet assured delivery, "store and forward" with route failover capability, set the standard for early medical network gateway products. The U.S. military and Loral/Siemens selected DeJarnette's ImageShare 910 products as their preferred modality interfaces for MDIS deployment.
Over the last decade, DeJarnette anticipated the demand for data migration as hospitals began to deploy newer PACS and released MDIG, our Migration Gateway Toolkit. We applied our expertise in data conversion to ensure that migrated exams were not only received by the new PACS, but could be displayed correctly. DeJarnette next developed dyseCT, its CT workflow engine that automatically splits whole body CT exams into separate studies based on the RIS orders. Finally, DeJarnette invented the vendor-neutral archive market with its xDL (Cross-enterprise Document Librarian), again using our expertise in data conversion so that a PACS can successfully receive and display foreign exams, i.e., exams originally performed by other hospitals.
