Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The performance characteristics and operation / usability of the Carestream DRX-Evolution 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-Evolution system including both software and hardware requirements. Nonclinical 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.
The linear tomography functionality was evaluated in bench testing using a tool phantom designed to evaluate this functionality, and also using anthropomorphic phantoms. Test results using the tool phantom were as expected, demonstrating accuracy of the tube head movement with respect to the capture device. In addition, linear tomography images were generated using four different anthropomorphic phantoms (chest, hand, knee and pelvis). The images were evaluated by a board-certified radiologist for diagnostic quality. Results of this evaluation demonstrated that the linear tomography images acquired using the DRX-Evolution system are of acceptable diagnostic quality. The tests described above and the performance data collected are consistent with the testing performed to substantiate the safety and effectiveness of linear tomography in the previously cleared reference device, Tomo-Link (K944967). The results of bench testing of new software / hardware components and phantom image evaluation of the linear tomography functionality support a substantial equivalence determination.
Clinical studies were 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 2530C Detector (K130464) and DRX-1C Detector (K120062). Results of these studies demonstrated equivalent or superior image quality to the DRX-1 Detector (predicate device).
Clinical studies were also performed to evaluate the DR Long Length Imaging Software (K130567), and Bone Suppression software (K133442). Results of the DR Long Length Imaging study demonstrated that the investigational software produced LLI images with statistically equivalent or better diagnostic capability to the predicate software. Results of the Bone Suppression clinical study demonstrated that the software generates a companion image that, when presented to the physician along with the standard-of-care image, is rated substantially equivalent or improved as compared to that of the predicate product (standardof-care image without the bone-suppressed companion image).
The results of the clinical testing described above support a substantial equivalence determination.

Device Description:
The DRX-Evolution is a diagnostic x-ray system utilizing digital radiography (DR) technology. The DRX-Evolution is designed for horizontal and upright projection exams. The system consists of a high voltage x-ray generator, overhead tube crane with
4
x-ray tube assembly, radiographic table with detector tray, Bucky image receptor on an upright wall stand, and x-ray controls containing a power distribution unit and operator PC (user interface).
The modifications to the device described in this submission include firmware and mechanical changes to facilitate use of the device for linear tomography exams and addition of a new generator option. Software updates to the DRX-Evolution include features such as Bone Suppression, Pneumothorax Visualization, and the ability to integrate the DRX-1C and DRX 2530C Detectors.
The new alternate generator has been implemented as an option for use with the DRX-Evolution system. Implementation of the new optional generator is transparent to the user and does not require any update to the user interface. The new generator is functionally equivalent to the generator cleared under the original 510(k) for this device.
The modifications to the DRX-Evolution device raise no new issues of safety or effectiveness.
Indications for Use / Intended Use:
The Indications for Use for the modified device, as described in its labeling, are: "The device is a permanently installed diagnostic x-ray system for general radiographic x-ray imaging including tomography. The tomography feature is not to be used for imaging pediatric patients." The Indications for Use for the modified device are similar to the originally cleared DRX-Evolution (predicate device) except for the addition of the tomography functionality that is not to be used for pediatric patients.
The intended use for the modified device, as determined by descriptions and the proposed labeling contained in this submission, is similar to the Indications for Use statement provided above. The linear tomography exam is considered a general radiography exam and is normally performed using a stationary x-ray system such as the DRX-Evolution. This exam requires accurate movement of the x-ray tube head with respect to the image capture device (and patient). This functionality is similar to the existing long length imaging function of the DRX-Evolution that controls accurate movement of the tube head and detector with respect to the patient.
Comparison of Technological Characteristics:
The modified DRX-Evolution device has the same technological characteristics as the originally cleared DRX-Evolution predicate device (K091889). In addition, firmware and hardware have been modified to enable accurate synchronized movement of the flat panel imager in the table with respect to movement of the tube head to add linear tomography functionality. Other added features such as the optional generator and new software options do not introduce new technological characteristics and are briefly described below.
5
Implementation of the alternative (optional) generator is transparent to the user and does not require changes to the existing selections pertaining to the generator available on the system console user interface.
The capability to perform linear tomography exams employs similar technology to the long length imaging feature that ensures proper synchronization of the tube head and detector for long length imaging exams. A longer exposure (approximately 3 seconds) is required for a linear tomography exam but the amount of radiation exposure is still within the window of some non linear tomography exams (i.e. exams for larger patients that require longer exposure to obtain a usable image).
Additional software features cleared by FDA for use on Carestream DR devices are extensions of the original image processing software incorporated in the DRX-Evolution system. These additional software features provide companion views to the original image than can be used to aid diagnosis. Incorporation of these optional features in the DRX-Evolution is consistent with its existing technological characteristics.
The DRX-Evolution can be used with the legally marketed Carestream DRX-1, DRX-1C and DRX 2530C detectors that are commercially available for use with other Carestream products or as standalone devices. The Carestream DRX-1 Detector utilizes a gadolinium oxysulfide (GOS) scintillator while the Carestream DRX-1C and DRX 2530C Detectors utilize a cesium iodide (CsI) scintillator, with all other aspects of the design and function remaining the same except for the size.
Ability to integrate Carestream's DRX-1C and DRX 2530C detectors with the DRX-Evolution required only minor updates to the user interface to select the detector being used so that exposure parameters are calculated appropriately. These detectors are functionally identical to the DRX-1 Detector except that they provide equal or superior image quality with respect to noise and spatial resolution at equivalent doses.
Discussion of Performance Testing - Bench:
The performance characteristics and operation / usability of the Carestream DRX-Evolution 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-Evolution system including both software and hardware requirements. Nonclinical 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.
The linear tomography functionality was evaluated in bench testing using a tool phantom designed to evaluate this functionality, and also using anthropomorphic phantoms. Test results using the tool phantom were as expected, demonstrating accuracy of the tube head movement with respect to the capture device. In addition, linear tomography images were generated using four different anthropomorphic phantoms (chest, hand, knee and
6
pelvis). The images were evaluated by a board-certified radiologist for diagnostic quality. Results of this evaluation demonstrated that the linear tomography images acquired using the DRX-Evolution system are of acceptable diagnostic quality. The tests described above and the performance data collected are consistent with the testing performed to substantiate the safety and effectiveness of linear tomography in the previously cleared reference device, Tomo-Link (K944967). The results of bench testing of new software / hardware components and phantom image evaluation of the linear tomography functionality support a substantial equivalence determination.
Discussion of Performance Testing - Clinical
Clinical studies were 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 2530C Detector (K130464) and DRX-1C Detector (K120062). Results of these studies demonstrated equivalent or superior image quality to the DRX-1 Detector (predicate device).
Clinical studies were also performed to evaluate the DR Long Length Imaging Software (K130567), and Bone Suppression software (K133442). Results of the DR Long Length Imaging study demonstrated that the investigational software produced LLI images with statistically equivalent or better diagnostic capability to the predicate software. Results of the Bone Suppression clinical study demonstrated that the software generates a companion image that, when presented to the physician along with the standard-of-care image, is rated substantially equivalent or improved as compared to that of the predicate product (standardof-care image without the bone-suppressed companion image).
The results of the clinical testing described above support a substantial equivalence determination.
