Intended Use

The intended uses of the NP-2600 Series Imagers is high resolution hard copy imaging of digital image source material and through the conversion of electronic signals from a wide variety of direct/indirect medical imaging modality outputs. The hardcopy output includes however is not limited to, digital radiography, nuclear medicine, ultrasound, CT, MRI, CR and Radiation Therapy planning; however, does not include digital mammography hardcopy. Images are suitable for medical image diagnosis use and referral. The system is intended for use by medical radiologists, imaging modality specialists, and communications to referring physicians.

Device Description

The NP-2600 Series Imagers are dry, thermal, color-only (NP-2600), grayscale only (NP-26xx) and grayscale/color(NP-2660) printer/imagers. The devices produce continuous tone, diagnostic quality BM images on transmissive film and reflective incident-light-viewed media. The color images produced via dye-diffusion technology are photographic quality implementing a "CRT to Image" matching process for medical applications.

AI/ML Overview

The provided text describes the Codonics NP-2600 Series Medical Dry Imagers, a device for high-resolution hardcopy imaging of digital medical images. However, it does not contain specific acceptance criteria or details of a study designed to prove the device meets such criteria in terms of analytical or clinical performance metrics.

The document states that "Laboratory tests have documented effective application and expected results consistent with predicate devices currently in commercial distribution and additional verification and validation testing is planned prior to release." This suggests that some testing was performed, but the specifics of acceptance criteria and a detailed study report are not present.

Here's a breakdown of the information that can be extracted and what is missing:

Electromagnetic standards complianceEN-60601-1-2 (2001)
Performance consistent with predicate devices"Laboratory tests have documented effective application and expected results consistent with predicate devices currently in commercial distribution"

Missing: Specific quantitative acceptance criteria (e.g., minimum spatial frequency response, specific density response tolerances, exact uniformity metrics). The current performance descriptions are generally qualitative or provide a single value without a defined acceptable range.


2. Sample size used for the test set and the data provenance

The document mentions "printer resolution pattern testing" and "clinical studies" were performed. However, it does not specify:

  • The sample size used for the test set (e.g., number of images, number of printouts).
  • The data provenance (e.g., country of origin of the data, retrospective or prospective).

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

The document mentions "clinical studies" and that images are "suitable for medical image diagnosis use." However, it does not specify:

  • The number of experts used to establish ground truth for any test set.
  • The qualifications of those experts (e.g., radiologist with 10 years of experience).

4. Adjudication method for the test set

The document does not mention any adjudication method for establishing ground truth or evaluating performance in a test set.


5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done

The document does not mention a multi-reader multi-case (MRMC) comparative effectiveness study. Therefore, there is no information on the effect size of how much human readers improve with AI vs. without AI assistance (as this is an imaging device, not an AI assistance tool in this context).


6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

The device is a hardcopy imager. Its "standalone" performance is described by its physical and performance characteristics (pixel size, resolution, color palate, etc.) and its ability to produce diagnostic quality images. The text states:

  • "The NP-2600 Series Imagers are dry, thermal, color-only (NP-2600), grayscale only (NP-26xx) and grayscale/color(NP-2660) printer/imagers."
  • "The devices produce continuous tone, diagnostic quality BM images on transmissive film and reflective incident-light-viewed media."
  • "The SMPTE resolution and contrast pattern and uniform density response function confirms quality suitable for the intended medical imaging use."

This confirms that its standalone performance in producing images was assessed against relevant industry standards (SMPTE pattern testing). However, specific metrics from these tests beyond general confirmation of suitability are not detailed as specific acceptance criteria or study results.


7. The type of ground truth used

The document implicitly refers to "diagnostic quality" images and "quality suitable for the intended medical imaging use." This suggests that the ground truth for image quality is based on industry standards and expectations for medical image diagnosis, likely involving visual assessment against reference patterns (like the SMPTE resolution and contrast pattern). However, it does not explicitly state the type of ground truth used (e.g., expert consensus, pathology, outcomes data) for a formal study dataset.


8. The sample size for the training set

The device is a printer/imager, not a machine learning algorithm that requires a training set in the typical sense. It relies on "industry standard format conversion software and image rendering algorithms" and "validating digital linear and visual linear routines and verified industry/modality specific Look Up Tables (LUTs)". Therefore, the concept of a "training set" for an algorithm isn't directly applicable in this context.


9. How the ground truth for the training set was established

As above, the concept of a training set for an algorithm is not applicable. The "ground truth" for the device's image rendering capabilities would be based on established colorimetry standards, grayscale standards, and visual perception requirements for diagnostic medical imaging.

3.1 Function

The NP-2600 Series Imagers are dry, thermal, color-only (NP-2600), grayscale only (NP-26xx) and grayscale/color(NP-2660) printer/imagers. The devices produce continuous tone, diagnostic quality BM images on transmissive film and reflective incident-light-viewed media. The color images produced via dye-diffusion technology are photographic quality implementing a "CRT to Image" matching process for medical applications.

3.2 Scientific Concepts:

Digital images, input directly or via Local Area Network, are managed via communication standards including however not limited to FTP, TCP/IP, and DICOM. Images of a variety of digital formats are managed via industry standard format conversion software and image rendering algorithms including however not limited to TIFF, GIF, PCX, BMP, PBM, PGM, PPM, XWD, JPEG, SunRaster, SGI, Targa, DICOM, DEFF, and Postscript. Interpolation and scaling of images without Lossy data compression is employed in this device to maintain data integrity. Validated digital linear and visual linear routines and verified industry/modality specific Look Up Tables (LUTs) are applied to optimize color and CRT image hardcopy display results.

Imaging is accomplished via directly-modulated discrete-element thin-layer linear thermal print head technology. The recording medium is either heat sensitive silver in the case of grev scale film, heat activated dye in the case of DirectVista® reflective record imaging, or thermal heat activated dye-diffusion from a color donor in the case of ChromaVista reflective or transmissive color imaging. The action of heat on the grey scale media produces a black dye in the medium. The action of heat on the dye-diffusion media produces a precision mixing of colors, which diffuse into the medium's top layer. The image formation is accomplished without wet chemistry processing common to many laser film imaging systems in use today.

3.3 Physical And Performance Characteristics:

In the case of medical image hard copy devices, important performance characteristics, which affect the effectiveness and safety, relate to the fidelity of the modulation transfer function. Spatial frequency response, grey scale resolution, density response and full image field uniformity combine to affect the final image. Characteristic response of thermal print head and film response must be mapped and compensated for to achieve suitable performance.

Pixel size (81u for the NP-2600 Series Imagers) produces a pixel resolution of 12.4 pixels/mm or 314 dpi. The grey scale resolution produces a palate of 256 levels of discernable grey, while the color palate produces 256 levels each of yellow, magenta and cyan for a total of 16.7 million colors. The SMPTE resolution and contrast pattern and uniform density response function confirms quality suitable for the intended medical imaging use.

    Codonics believes the NP-2600 Series Imagers to be substantially equivalent to Medical Image Hardcopy Devices currently in commercial distribution in the U.S. We have selected the Codonics NP-1660 Series Medical Printers (Premarket notification K003481 Codonics Horizon Series Medical Hardcopy Dry Imagers (Premarket notification K021054), Codonics EP-1000 Medical Image Hardcopy Color Printers (premarket notification K030690) and the Seiko ColorPoint 1720 (Premarket notification K991282) as the predicate devices for our claim of substantial equivalence, Attachment 6 contains information describing these predicate devices and provides a comparison of the NP-2660 Series Imagers to the predicate device(s) and describes how any differences of note are substantially equivalent.

7 Hazard Analysis and Safety Concerns

7.1Hazard analysis on this product has been performed throughout the product concept and testing phases of the 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;
  • . Determine any effect on patient safety and system effectiveness

The potential hazards associated with this product are not different than those of other hardcopy image components. These are primarily related to the failure of computer system components, and may be variously obviated by decisions taken by the end users of the product. None of the failures are expected to materially contribute to patient death or injury.

It is our conclusion that no hardware or software component, operating in a properly configured environment, whose latent design defect would be expected to result in death or injury of the patient. Thus the "level of Concern" is "Minor".
