Device Story

The IiVS™ Integrated image Viewing Station (DiVS/IiVS) is a teleradiology system for medical image management. It accepts DICOM-compliant medical images and NTSC video signals as input. The system operates on Silicon Graphics workstations (SGI-320/540) running Windows NT 4.0. It provides tools for image viewing, 3D visualization (voxel transmission, ray casting), and report generation. Radiologists use the system to annotate images, create reports, and distribute findings over networks. Output includes DICOM files, JPEG/BMP images, and NTSC video. The system supports clinical decision-making by facilitating the review of diagnostic images and the creation of digital reports. It benefits patients by enabling efficient teleradiology workflows, allowing for remote expert consultation and faster access to diagnostic information.

Clinical Evidence

No clinical data provided. The submission relies on bench testing and verification of software life cycle processes according to ISO/IEC 12207:1995.

Technological Characteristics

Workstation-based software (SGI VW-320/540). Inputs: DICOM 3.0, NTSC video. Outputs: DICOM, JPEG, BMP, NTSC video. Features: 3D volume rendering (voxel transmission, ray casting), 8-object segmentation, clipping planes, and orthogonal plane display. Connectivity: Ethernet 100 Base T. Software developed per ISO/IEC 12207:1995. User interface: Keyboard and wheel-mouse.

Indications for Use

Indicated for the acquisition, storage, transmission, and display of medical images and patient reports for teleradiology applications. No specific patient population, age, or gender restrictions are defined.

Regulatory Classification

Identification

A medical image communications device provides electronic transfer of medical image data between medical devices. It may include a physical communications medium, modems, and interfaces. It may provide simple image review software functionality for medical image processing and manipulation, such as grayscale window and level, zoom and pan, user delineated geometric measurements, compression, or user added image annotations. The device does not perform advanced image processing or complex quantitative functions. This does not include electronic transfer of medical image software functions.

### Equivalent Device(s):

Acculmage™ Viewer Products, K961023, by Acculmage, Inc.

The referenced systems are equivalent to the DVS and IiVS™ Integrated image Viewing Stations in terms of basic design, features and intended use.

### Description of the Device:

The IiVS™ Integrated image Viewing Station is a product family, which comes in two different versions:

DiVS: a DICOM viewer liVS: a 3D viewer

The intended use of the devices is to provide solutions to various medical image-viewing problems, which come about as the modalities generate more and more images. They also support image distribution over networks, and are DICOM conformant.

Finally, the IIVS™ Integrated image Viewing Station family supports the radiologist in writing a report, and transmitting and storing this report in digital form.

### Manufacturing Facility:

Manadalanting I dolling.
At the present time, the DVS & IiVS™ Integrated image Viewing Station is manufactured by TeraRecon, Inc.

### Performance Standards:

There are no applicable FDA mandated performance standards for this device. However, voluntary standards such as DICOM, various in-house Standard Operating Procedures and vendor qualification procedures are in place and utilized in the production of the software.

The software designed to control and manipulate the diagnostic images follows the international standard ISO/IEC 12207: 1995 Informatin technology - Software Life Cycle Processes. In accordance with that standard, the level of concern relative to this software has been determined using the decision tree provided in Version 1 of the FDA Software Guidance.
