No
The document explicitly states "There is no image processing or compression used with this software" and there are no mentions of AI, DNN, or ML. The compression algorithms used are standard DICOM 3.0.
No
The device is a DICOM image compressor that facilitates the transfer of medical images; it does not directly treat or diagnose medical conditions.
No
This device is described as a DICOM image compressor and a secondary image capture application for film digitizers. Its purpose is to facilitate the efficient transfer of medical images between DICOM entities (like viewing stations and databases) and to capture images. It does not perform any diagnostic functions or analyze images for diagnostic purposes.
Yes
The device is described as a "Microsoft Windows NT or Windows 95 based application" and an "expansion module" to existing software. It performs a function (DICOM image compression) that is purely software-based and does not involve any physical components or hardware modifications beyond the existing PC and film digitizer. The description focuses solely on the software's functionality and compatibility.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is clearly stated as a "DICOM image compressor" to facilitate the efficient transfer of medical images. This is a function related to image management and communication, not the analysis of biological samples or the diagnosis of disease based on such analysis.
- Device Description: The description reinforces its role as an "expansion module to Digitizer Director" which is a "DICOM 3.0 compliant secondary image capture application." This further emphasizes its function within the medical imaging workflow, specifically related to capturing and managing images from film digitizers.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, tissue, etc.), detecting specific analytes, or providing diagnostic information based on laboratory tests. The focus is solely on the technical process of image compression and transmission.
Therefore, the DIGITIZER DIRECTOR: Image Compression Module falls under the category of medical imaging software or a component within a medical imaging system, but not an In Vitro Diagnostic device.
N/A
Intended Use / Indications for Use
The intended use of DIGITIZER DIRECTOR: Image Compression Module is as a DICOM image compressor that will enable any hospital or medical facility PC with adequate memory and the appropriate film digitizer to send images to other DICOM entities such as viewing stations and databases in an efficient manner. The compression algorithms used are fully supported by the DICOM 3.0 Standard.

§ 892.2050 Medical image management and processing system.
(a)
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.(b)
