Indications for Use
The product is an image processing workstation software package designed to run on standard PC hardware. The hardware is all "off-the-shell" and may be purchased independently by the end user or from AccuImage. The AccuImage, AccuView software receives image files from medical scanning devices, such as CT or MRI and performs real-time viewing, image manipulation, 3D and 4D visualization, communication, and archiving.
Device Story
AccuView is a diagnostic imaging workstation software package running on standard PC hardware (Windows 95/98/NT). It receives medical image files (CT, MRI) via DICOM 3.0, ACR NEMA 2.0, or proprietary formats. The software performs real-time image processing, including window/level, pan, zoom, filtering, and cine display. Plug-ins provide advanced functionality: AccuScore (3D calcium scoring using volumetric Agatston algorithm), AccuAnalyze, AccuShade, AccuVRT, and AccuMIP (volume/surface rendering). AccuScope enables virtual endoscopy (fly-through of anatomic cavities) with auto-flight path calculation and collision detection. Used by clinicians in clinical settings to visualize and analyze patient anatomy. Output includes processed images, 3D/4D reconstructions, and calcium scoring reports. These outputs assist clinicians in diagnostic decision-making and patient assessment.
Clinical Evidence
Bench testing only. No clinical data provided. The device was validated through design, coding, and testing phases, including hazard analysis, to ensure safety and effectiveness equivalent to existing PACS components.
Technological Characteristics
Software-based workstation running on standard PC hardware (Dual 400 MHz Pentium, 512 MB RAM). Connectivity via TCP/IP and GPIB. Supports DICOM 3.0, ACR NEMA 2.0, and proprietary formats. Image processing includes window/level, filtering, 3D/4D volume rendering (MIP, MinIP, surface rendering). AccuScore uses volumetric Agatston algorithm for calcium scoring. AccuScope provides virtual endoscopy with auto-flight path and collision detection. Software level of concern is Minor.
Indications for Use
Indicated for use as an image processing workstation software package for the viewing, manipulation, 3D/4D visualization, communication, and archiving of medical images (CT/MRI) by clinicians.
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).

## 6. Device Description and Intended Use
The AccuView Diagnostic Imaging Workstation Software Package with Plug-ins receive image files from medical scanning devices, such as CT or MRI and performs real-time viewing, image manipulation, three and four dimensional visualization, communication, and archiving. All of the functions are supported on standard communication, and them for ease of cost and maintenance. The use of Microsoft Windows 95/98/NT operating system makes the AccuView Diagnostic Imaging Workstation Software Package with Plug-ins easy to use and capable of being integrated with other computer needs.
#### 7. Software
Acculmage Diagnostics Corporation certifies that the AccuView Diagnostic Imaging Workstation Software Package with Plug-ins are designed, developed, tested and validated according to written procedures. These procedures identify individuals within the organization responsible for developing and approving product specifications, coding and testing, validation testing and field maintenance.
#### 8. Hazard Analysis
Hazard analysis on this product has been performed throughout the definition, design, coding and testing phases of product development and implementation. This process has emphasized:
- identification of potential hazards, their causes, and their effects; .
- development of methodologies to control the occurrence of hazards and to . constrain their effects; and
- Determine any effect on patient safety and system effectiveness. .
The potential hazards associated with this software product are no different than those of other PACS components . These are primarily related to failure of computer system components, and may be variously obviated by decisions taken by the customers of this product. None of these failures are expected to materially contribute to patient death or injury.
It is our conclusion that there is no hardware or software component, operating in a properly configured environment, whose failure or latent design defect would be expected to result in death or injury of a patient. Thus the "Level of Concern" is "Minor".
