The WV1417A Digital X-ray Direct Imaging Flat Panel Detector System provides a digital image capture capability for conventional radiographic examinations (excluding fluoroscopic, angiographic, and mammographic applications). The device has application wherever conventional screen-film systems are currently used.
The WV1417A Digital X-ray Direct Imaging Flat Panel Detector System is used to directly capture and convert conventional projection X-ray images to digital images. A image preview function can be displayed on a review monitor for viewing. The diagnostic image can be transmitted through LAN for diagnostic viewing and printing. The device provides digital image capture for conventional radiographic examinations, excluding fluoroscopic, angiographic and mammography applications. The system differs from traditional X-ray systems in that instead of exposing a film for subsequent wet chemical processing to create a hardcopy image, a device called a detector array is used to capture the image in electronic form. The digital data are then used to produce hardcopy and softcopy images. The WV1417A Digital X-ray Direct Imaging Flat Panel Detector System (Fig.VI-1) is composed of the following: A detector array is used to capture the diagnostic image. An array controller is used to control detector array, harmonize the working between the array controller and high-voltage generator for exposal synchronization and image transmission. A system controller is used to enter patient demographic information, initiate the exposure process, review captured images, and accept or reject captured images. The system controller is also used to send images to a hardcopy printer, workstation, or archive, and manage images temporarily stored in its database. Here, the system controller is the software device and which should install in the PC hardware system purchased by themselves of customer. The system controller also can make some disposal for the original image, such as gain, offset and defective pixel correction. By capturing, previewing, and storing and image, the system enables an operator to check the quality of an image at the time of exposure without having to develop a film.
The provided text does not contain specific acceptance criteria or a detailed study proving the device meets said criteria. It primarily focuses on the device's administrative and descriptive information for its 510(k) submission.
However, based on the limited information provided, here's what can be extracted and inferred:
1. A table of acceptance criteria and the reported device performance:
The document states, "All the information about the device performance has provided. The Clinical Test Report has provided." This indicates that performance data was submitted, but the specific acceptance criteria and the detailed performance results are not included in the provided text. We only know that electrical safety and electromagnetic compatibility tests were conducted and the device was found substantially equivalent to a predicate device.
| Acceptance Criteria | Reported Device Performance |
|---|---|
| Electrical Safety (IEC 60601-1) | Compliant (as implied by regulatory clearance) |
| Electromagnetic Compatibility (IEC 60601-1-2) | Compliant (as implied by regulatory clearance) |
| Substantial Equivalence to Predicate Device | Achieved (as stated in the 510(k) summary) |
| Image Capture Capability for Conventional Radiographic Examinations (excluding fluoroscopic, angiographic, and mammographic applications) | Demonstrated (as per intended use and regulatory clearance, though specific metrics are not detailed) |
2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
The document mentions "The Clinical Test Report has provided." However, there is no information regarding:
- The sample size used for the test set.
- The country of origin of the data.
- Whether the data was retrospective or prospective.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)
The provided text does not contain any information about the number of experts, their qualifications, or how ground truth was established for a test set. This detail would typically be found within the clinical test report, which is not included here.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
The provided text does not contain any information about the adjudication method used for the test set.
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
The provided text does not indicate that an MRMC comparative effectiveness study was done. The device description suggests it's a direct imaging system, not an AI-assisted diagnostic tool, thus this type of study would likely not be relevant to its intended use as described.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
The device is a "Digital X-ray Direct Imaging Flat Panel Detector System," which captures and converts X-ray images. It's an imaging hardware system, not an algorithm that performs standalone analysis. Therefore, a standalone performance study of an algorithm is not applicable in this context. The focus is on the quality of the captured digital image compared to traditional film.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
The provided text does not specify the type of ground truth used in any clinical testing. Given its function as an imaging detector, ground truth would likely involve image quality metrics compared against a predicate device or established standards for conventional radiography, potentially assessed by expert radiologists, but this is not explicitly stated.
8. The sample size for the training set
Given that this is a hardware device for digital image capture and not an AI/machine learning algorithm, the concept of a "training set" in the traditional sense is not applicable.
9. How the ground truth for the training set was established
As described in point 8, the concept of a "training set" is not applicable for this device.
