The KODAK DRYVIEW 8900 Laser Imager with Mammography Accessory is intended to provide high-resolution hard copy images from digital imaging source output signals. The device is intended for use with KODAK DRYVIEW DVM film for use with a variety of digital modalities, including, but not limited to, CR (Computed Radiology), DR (Digital Radiology) and FFDM (Full Field Digital mammography). The images are to be used for medical diagnosis medical and referring physicians and their patients.
The KODAK DRYVIEW 8900 Laser Imager Mammography Accessory's intended use is as a hard copy device for output from imaging source modalities for use in medical imaging diagnosis and referral. Electronic image information signals are managed in the 8900 and transformed optically to expose KODAK DRYVIEW imaging media. The system is intended for use with a variety of digital modalities, including, but not limited to CR, DR, CT, MR, Ultrasound, Nuclear Medicine, FFDM etc. for diagnostic use by medical radiologists and communications to referring physicians and their patients.
The subject device and predicate devices use the same technical design base. The printers receive image data from the modality. User control is performed directly by the modality or through the host control. KODAK DRYVIEW imaging media is removed from a daylight cartridge and transported to the laser imaging station. Image data and media merge at the laser station and the film is scanned. The exposed media is transported through the integrated processor and exits the printer.
Software is used to control the image management and machine functions. AIQC (Automated Image Quality Control) matches printing power with film characteristics to provide consistently high image quality.
The provided text describes a 510(k) summary for the KODAK DRYVIEW 8900 Laser Imager with Mammography Accessory. This document outlines the device's intended use and technological characteristics, and importantly, references performance data related to its safety and effectiveness. However, it does not detail specific acceptance criteria or a study demonstrating the device meets those criteria in the way typically expected for an AI/ML medical device.
The "Performance Data" section states that "Safety and effectiveness are assured via meeting voluntary standards, including: DICOM, SMPTE, UL 60950, IEC 60601-1-1-1, IEC 60825-1, ISO 12207, and ISO 14971." This indicates that compliance with these established standards serves as the basis for demonstrating safety and effectiveness, rather than a novel clinical or algorithmic performance study with specific acceptance metrics.
This device is a hard copy device (laser printer) for medical images, not an AI/ML diagnostic or prognostic algorithm. Therefore, the questions related to AI performance metrics, ground truth, expert adjudication, training/test sets, and human-in-the-loop assessments are not applicable to this type of device submission.
Here's a breakdown based on the information provided, recognizing the nature of the device:
-
Table of Acceptance Criteria and Reported Device Performance:
The document does not present a table of specific quantitative acceptance criteria or device performance metrics in the format usually associated with diagnostic accuracy (e.g., sensitivity, specificity, AUC). Instead, it relies on compliance with broader industry and safety standards to assure performance.
Acceptance Criteria (Implied) Reported Device Performance Compliance with DICOM standard for medical imaging communication Assured via meeting DICOM voluntary standard. Compliance with SMPTE standard for display performance Assured via meeting SMPTE voluntary standard. Compliance with safety standards (UL, IEC, ISO) Assured via meeting UL 60950, IEC 60601-1-1-1, IEC 60825-1, ISO 12207, and ISO 14971 voluntary standards. Consistency between input signals and output density Assured by the incorporation of a test pattern generator and an Automatic Image Quality Control (AIQC) system. "AIQC (Automated Image Quality Control) matches printing power with film characteristics to provide consistently high image quality." Both the subject and predicate devices are high-resolution printers with incorporated test patterns to assist in MQSA (Mammography Quality Standards Act) quality assurance testing. -
Sample Size Used for the Test Set and Data Provenance:
- Sample Size: Not applicable. This is not a study assessing diagnostic performance on a dataset of patient images.
- Data Provenance: Not applicable.
-
Number of Experts Used to Establish Ground Truth and Qualifications:
- Not applicable, as this is a device for outputting images, not an algorithm that generates diagnostic insights requiring ground truth.
-
Adjudication Method:
- Not applicable.
-
Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study:
- No, an MRMC study was not done. This type of study is for evaluating diagnostic performance of an AI system, which is not the function of this device. The document mentions that "Medical personnel review images displayed by the subject device and its predicates," indicating human interpretation of the printed output.
-
Standalone Performance Study (Algorithm Only):
- Not applicable. This device is a printer, not a standalone algorithm. Its "software" controls image management and machine functions, and its AIQC system monitors output quality, but it does not perform diagnostic algorithms.
-
Type of Ground Truth Used:
- Not applicable. The performance assurance is based on adherence to engineering and safety standards, and the physical quality control of the printing process (AIQC, test patterns), rather than diagnostic accuracy against a clinical ground truth.
-
Sample Size for the Training Set:
- Not applicable. The device's functionality does not involve a "training set" in the context of machine learning.
-
How Ground Truth for the Training Set Was Established:
- Not applicable.
Summary of the Study Proving Device Meets Acceptance Criteria:
The "study" or rather, the evidence proving the device meets its acceptance criteria, is based on a demonstration of compliance with established industry and safety standards, and the inherent design features for quality control.
- Reliance on Voluntary Standards: The primary method for assuring safety and effectiveness is by meeting voluntary standards such as DICOM, SMPTE, UL 60950, IEC 60601-1-1-1, IEC 60825-1, ISO 12207, and ISO 14971. These standards provide specifications for various aspects, including image communication, display performance, electrical safety, laser safety, software lifecycle processes, and risk management.
- Technological Equivalence to Predicate Device: The submission emphasizes that the subject device (KODAK DRYVIEW 8900) uses the "same technical design base" as the predicate device (KODAK DRYVIEW 8610), which was already cleared. This "substantial equivalence" is a core tenet of the 510(k) pathway.
- Intrinsic Quality Control Mechanisms: The device incorporates a "test pattern generator" and an "Automatic Image Quality Control (AIQC) system." The AIQC system "matches printing power with film characteristics to provide consistently high image quality." Both the subject and predicate devices include test patterns to help with MQSA quality assurance testing, which is crucial for mammography equipment. These features are designed to ensure the printer consistently reproduces high-quality images.
In essence, the "study" is an engineering and quality assurance process demonstrating that the device's design and built-in controls enable it to operate reliably and safely, adhering to recognized industry benchmarks for hardcopy medical imaging. It is not a clinical trial or an AI performance validation study.
