Intended Use

The Essence 55S Large Monitor System (Essence 55S) is intended to be used by health care professionals to integrate the video output from various commercially-available instruments commonly used in a medical procedure laboratory into a single video display.

Device Description

The Essence 55S Large Monitor System is a large color LCD monitor for viewing images derived from several video sources on a single display and to rearrange these images to the situational requirements of the user. Thanks to the advantages of the large widescreen monitor, the data can be collected from the video sources using the optional video wall controller AVS-540 and fed into the large display via the DVI lines and / or DP. The optical graphic extension module M1-201SA-TR can be used to convert / transmit the video signal, and the common PC can be taken as a video device.

AI/ML Overview

The provided 510(k) summary (K172969) describes a medical monitor, the Essence 55S Large Monitor System. The acceptance criteria and the study that proves the device meets them are based on comparisons to a predicate device and bench testing.

1. Table of Acceptance Criteria and Reported Device Performance

The device is a medical monitor, and its "performance" is primarily defined by its technical specifications and its ability to integrate video output for medical professionals. The acceptance criteria are implicitly met by demonstrating substantial equivalence to a predicate device and successful bench and system tests.

Acceptance Criteria CategorySpecific Criteria (Implied)Reported Device Performance (Essence 55S)
Intended UseSame as predicate device."The intended use of Essence 55S Large Monitor System (Essence 55S) is totally same as that of the predicate device."
Technological CharacteristicsEquivalent to predicate; differences do not affect safety/effectiveness.Demonstrated through detailed comparison table (Table 2) and the conclusion that "technological characteristics differences do not affect the safety and effectiveness, no new risk is raised."
Display CharacteristicsEquivalent to predicate."The test results showed that the Essence 55S Large Monitor System is with display characteristics equivalent to those of the predicate device, RadiForce Large Monitor System except some items, each of which was determined that it would not affect observer's performance."
Safety & EffectivenessNo new risks introduced.Concluded that differences "do not affect the safety and effectiveness, no new risk is raised."
Performance TestingSuccessful completion of Display bench, validation, and system tests."The following tests were successfully performed to validate the Essence 55S Large Monitor System: Display bench tests, Display validation tests, System tests."

2. Sample Size Used for the Test Set and Data Provenance

This is a medical display device, not an AI or diagnostic imaging device. Therefore, the concept of a "test set" in the context of patient data or clinical images is not applicable. The "tests" performed are engineering and performance validation tests.

  • Sample Size: Not applicable in the context of patient data. The "sample" would be the device itself (Essence 55S Large Monitor System).
  • Data Provenance: Not applicable. The "data" are technical specifications and test results generated from the device in a laboratory setting.

3. Number of Experts Used to Establish Ground Truth and Qualifications

Not applicable. Ground truth, in the context of expert consensus on medical images, is not relevant for a medical display device. The "ground truth" for this device's performance is its adherence to technical specifications and safety standards, as verified through engineering tests.

4. Adjudication Method for the Test Set

Not applicable. Adjudication methods (like 2+1 or 3+1) are used for resolving disagreements among human readers in interpreting medical images. This device is a display, not an interpretation tool.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done

No, an MRMC comparative effectiveness study was not done. Such studies are typically performed for diagnostic devices or AI algorithms that assist in interpretation, to measure the impact of the device on human reader performance. This device is a monitor, not an interpretative aid.

6. If a Standalone (Algorithm Only Without Human-in-the-Loop Performance) Was Done

Yes, but not in the typical sense of an "algorithm-only" performance for a diagnostic task. The "standalone" performance here refers to the device's technical specifications and functionality as a display system, independent of a human's diagnostic interpretation using the displayed images. The "Display bench tests," "Display validation tests," and "System tests" are essentially standalone performance evaluations of the monitor.

7. The Type of Ground Truth Used

The "ground truth" for this device is based on:

  • Technical Specifications: Adherence to defined physical and electrical parameters (e.g., resolution, brightness, contrast, response time).
  • Regulatory Standards: Compliance with relevant medical device safety and performance standards (e.g., EN60601-1, ANSI/AAMI ES60601-1, FCC-B, RoHS).
  • Predicate Device Equivalence: The performance and characteristics of the legally marketed predicate device (RadiForce Large Monitor System) serve as a benchmark for substantial equivalence.

8. The Sample Size for the Training Set

Not applicable. This device is a hardware display system, not a machine learning model that requires a "training set" of data.

9. How the Ground Truth for the Training Set Was Established

Not applicable, as there is no training set for this type of device.
