The DRX-Revolution Mobile X-ray System (also referred to as the DRX-Revolution) is a diagnostic mobile x-ray system utilizing digital radiography (DR) technology. The DRX-Revolution consists of a self contained x-ray generator, image receptor(s), imaging display and software for acquiring medical diagnostic images outside of a standard stationary x-ray room. The DRX-Revolution system incorporates a flat-panel detector that can be used wirelessly for exams such as in-bed chest projections. The system can also be used to expose CR phosphor screens or film.
The provided text is a 510(k) Summary for the Carestream DRX-Revolution Mobile X-ray System. It describes the device, its intended use, and a comparison to a predicate device. It also briefly mentions testing performed. However, it does not contain specific acceptance criteria, a detailed study description with performance metrics, sample sizes for test/training sets, ground truth establishment, expert qualifications, or MRMC study results.
The only study mentioned is a "concurrence study of clinical image pairs" (also referred to as a "Reader Study") conducted in accordance with "Guidance for the Submission of 510(k)'s for Solid State Imaging Devices" to demonstrate diagnostic capability. The outcome was that the DRX-Revolution system was "statistically equivalent to or better than that of the predicate device."
Therefore, based only on the provided text, I cannot fill in most of the requested information.
Here's what can be extracted:
1. Table of Acceptance Criteria and Reported Device Performance
| Acceptance Criteria | Reported Device Performance |
|---|---|
| Not specified in the provided text. | "statistically equivalent to or better than that of the predicate device" (for diagnostic capability) |
2. Sample size used for the test set and the data provenance
- Sample Size (Test Set): Not specified. The study is referred to as a "concurrence study of clinical image pairs" and a "Reader Study," implying a set of images was used.
- Data Provenance: Not specified (e.g., country of origin, retrospective/prospective).
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
- Number of Experts: Not specified.
- Qualifications of Experts: Not specified.
4. Adjudication method for the test set
- Adjudication method: Not specified.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
- A "Reader Study" was done comparing the DRX-Revolution system to a predicate device. This implies human readers were involved. However, it was not an MRMC comparative effectiveness study involving AI assistance vs. without AI assistance. The study compared two different imaging systems.
- Effect Size: Not specified.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
- The "Reader Study" assessed diagnostic capability by human readers using the system. It does not mention a standalone algorithm-only performance assessment.
7. The type of ground truth used
- The text describes a "concurrence study of clinical image pairs" to demonstrate "diagnostic capability." This suggests that the ground truth would likely be based on a clinical diagnosis or expert interpretation against which the images from both systems were compared. However, the specific type of ground truth (e.g., expert consensus, pathology, outcomes data) is not explicitly stated.
8. The sample size for the training set
- No training set is mentioned as this device is an X-ray system, not typically an AI/machine learning device that requires a training set in the conventional sense for its core function described here.
9. How the ground truth for the training set was established
- Not applicable; no training set mentioned.

Class II IZL 21 CFR 892.1720
Shimadzu MobileDaRt Manufactured by Shimadzu Corp. 510(k) No. - K041763 (July 13, 2004)
Device Description:
The DRX-Revolution Mobile X-ray System (also referred to as the DRX-Revolution) is a diagnostic mobile x-ray system utilizing digital radiography (DR) technology. The DRX-Revolution consists of a self contained x-ray generator, image receptor(s), imaging display and software for acquiring medical diagnostic images outside of a standard stationary x-ray room. The DRX-Revolution system incorporates a flat-panel detector that can be used wirelessly for exams such as in-bed chest projections. The system can ' also be used to expose CR phosphor screens or film.
Indications for Use / Intended Use:
The Indications for Use for the device, as described in its labeling, are:
{1}------------------------------------------------
"The device is designed to perform radiographic x-ray examinations on all pediatric and adult patients, in all patient treatment areas."
The intended use for this device, as determined by descriptions and the proposed labeling contained in this submission, is similar to the Indications for Use statement provided above. The DRX-Revolution is a mobile system used to generate and control x-rays for diagnostic procedures. We believe that the DRX-Revolution and the predicate device have the same intended use.
The Indications for Use for the subject device is different than the predicate device, but these differences do not alter the intended diagnostic use of the device. Differences are appropriately characterized as descriptive, and the intended use remains unchanged. Any variation in features or technical specifications have been identified and addressed through testing (described below) to support a substantial equivalence determination.
Comparison of Technological Characteristics:
The DRX-Revolution Mobile X-ray System is substantially equivalent to the predicate device, the Shimadzu MobileDaRt (MUX-100D). The DRX-Revolution Mobile X-rav System and the Shimadzu MobileDaRt system both consist of an x-ray generator, x-rav tube, collimator, and graphical user interface on an operator console with touch screen monitor. These components are mounted on a motorized cart that is battery powered to enable the device to be moved from location to location. Both systems utilize a digital flat panel detector for image capture and can also be used to expose CR storage phosphor or film cassettes. Both systems have operator console software with image processing capability.
Discussion of Testing
The performance characteristics and operation / usability of the DRX-Revolution system were evaluated in non-clinical (bench) testing. These studies demonstrated the intended workflow, related performance, overall function, verification and validation of requirements for intended use, shipping performance, and reliability of the DRX-Revolution system including both software and hardware requirements. Non-clinical test results have demonstrated that the device conforms to its specifications. Predefined acceptance criteria were met and demonstrated that the device is as safe, as effective, and performs as well as or better than the predicate device.
A concurrence study of clinical image pairs was performed in accordance with FDA guidance document "Guidance for the Submission of 510(k)'s for Solid State Imaging Devices" to demonstrate the diagnostic capability of the DRX-Revolution system. Results of the Reader Study indicated that the diagnostic capability of the DRX-Revolution Mobile X-ray System is statistically equivalent to or better than that of the predicate device. These results support a substantial equivalence determination.
