Intended Use

Pegasys InTouch™ software is intended to transfer and provide interpretive displays of Pegasys and DICOM image data either compressed or uncompressed to physician workstations via a local area network (LAN) interconnected with Ethernet or via a wide area network (WAN) comprised of two or more LANs in different locations, using a hospital intranet, not the Internet.

Device Story

Pegasys InTouch™ is a PACS software application for remote viewing of medical images. It accepts Pegasys and DICOM image data transmitted via hospital LAN/WAN. The system enables physicians to display, store, and interact with images on standard WinTel PCs. Features include multi-zone display (up to 9 zones), tomographic comparative displays, and cardiac stress/rest comparative analysis (including cine motion). The device facilitates clinical interpretation by allowing simultaneous viewing of datasets at different locations. It does not alter image data. Benefits include improved physician access to diagnostic information outside the original study area, supporting clinical decision-making through remote image review.

Clinical Evidence

Bench testing only. A prototype of the display application was used to download and display DICOM-format images in four display regions to verify image integrity and display functionality.

Technological Characteristics

PC-compatible hardware (microprocessor, RAM, monitor, keyboard, mouse/trackball, hard drive). Connectivity via Ethernet or modem. Software runs on WinTel systems using Microsoft Internet Explorer 3.0 or Netscape Navigator 3.0. Supports DICOM standard. No specialized materials or energy sources; standard digital computing environment.

Indications for Use

Indicated for physicians to remotely view and interpret Pegasys and DICOM medical images (e.g., SPECT, cardiac stress/rest) via hospital LAN/WAN networks.

Regulatory Classification

Identification

A medical image management and processing system is a device that provides one or more capabilities relating to the review and digital processing of medical images for the purposes of interpretation by a trained practitioner of disease detection, diagnosis, or patient management. The software components may provide advanced or complex image processing functions for image manipulation, enhancement, or quantification that are intended for use in the interpretation and analysis of medical images. Advanced image manipulation functions may include image segmentation, multimodality image registration, or 3D visualization. Complex quantitative functions may include semi-automated measurements or time-series measurements.

Special Controls

*Classification.* Class II (special controls; voluntary standards—Digital Imaging and Communications in Medicine (DICOM) Std., Joint Photographic Experts Group (JPEG) Std., Society of Motion Picture and Television Engineers (SMPTE) Test Pattern).

D. Device Description:

Pegasus InTouch™ has been developed to provide a physician with the ability to review Pegasus and DICOM images from locations outside the original study area. Pegasus InTouch™ has been designed to operate on standard, off-the-shelf hardware and software components. Using standard WinTel PC systems and the hospital proprietary LAN/WAN (either local or wide area), physicians will have the ability to review and interact with patient data from their desks.

Pegasus and other digital imaging communications systems consist of a computer with a high speed data modem connected to a standard telephone line or computer network that can transmit or receive digitized images. The system is programmed to send, receive, store, copy and display these images in a manner that assures that images are not altered. Operator interface features are also computer controlled so as to enhance the system's capabilities and make the system more user friendly. Images can be displayed with different resolutions and colors; the same image set can be viewed simultaneously at different locations on designated physician workstations.

The physician has the capability to select a variety of display formats for viewing. For example, the physician may select up to 9 separate datasets to be displayed simultaneously, including whole body and snapshot displays; comparative (tomographic) displays of oblique or transverse files; comparative cardiac SPECT data; and SPECT and gated SPECT data in a 10 frame-per-second cine mode. A brief description of the applications available to the physician workstation follows.

1. The physician may select from a number of display formats incorporating from 1 to 9 zones as described previously.
2. A Tomographic Display is used to display multiple orientations of the same image set in a comparative manner.
3. The Cardiac Stress/Rest Comparative application facilitates the visual comparison of the same cardiac locations during rest and during stress.
4. Cardiac Comparatives is similar to the Stress/Rest application above, but displays the stress and rest projections in cine motion.

E. Indications for Use:

Pegasys InTouch™ software is intended to transfer and provide interpretive displays of Pegasys and DICOM image data either compressed or uncompressed to physician workstations via a local area network (LAN) interconnected with Ethernet or via a wide area network (WAN) comprised of two or more LANs in different locations, using a hospital intranet, not the Internet.

F. Technological Comparison:

Pegasys InTouch™ is similar to a wide variety of Picture Archive and Communication Systems (PACS) currently on the market. These systems are designed to send, receive, store, copy and display high resolution digitized images. The images can be digitally scanned into the system or captured from various imaging modalities such as CT and MRI. Each system consists of either a single unit or multiple units networked. Image data is sent from a sending unit through digital network lines or through standard telephone lines by a high speed modem to a receiving station. Once the image is received, it can be stored, copied and displayed. Displayed images may be adjusted for user preference to assist in interpretation.

Pegasus InTouch™ and other currently marketed systems consist of a PC compatible computer with a microprocessor with RAM, monitor, keyboard, mouse/trackball, internal hard drive, modem or Ethernet connection, and Microsoft Internet Explorer 3.0 or Netscape Navigator 3.0.

## II. Testing

An image was generated using a prototype of the display applications. The DICOM-format image was downloaded using standard web-based data transfer and displayed into the image viewer. The same image was displayed in each of the four display regions.
