简要总结

The purpose of this clinical study is to evaluate the imaging performance of the DRX Plus 3543 and DRX Plus 3543C Detectors (flat panel digital imaging devices) as compared to the currently marketed Carestream DRX-1 Detector. The results of this study will be included in a Traditional 510(k) FDA Submission to obtain clearance to market the new detectors in the US. The study was designed in accordance with the FDA Guidance titled "Guidance for the Submission of 510(k)'s for Solid State X-ray Imaging Devices", issued on August 6, 1999.

详细描述

The purpose of this clinical study is to evaluate the imaging performance of the DRX Plus 3543 and DRX Plus 3543C Detectors (flat panel digital imaging devices) ("investigational device") as compared to the currently marketed Carestream DRX-1 Detector ("predicate device"). The evaluation will consist primarily of comparing the diagnostic image quality of double-imaged pediatric and adult cadaver studies and adult live human subject studies acquired under the same exposure technique for similar detector types (i.e. comparing DRX-1 GOS predicate with DRX Plus GOS) or exposure adjusted technique when different detector types are compared.

Under the same position and radiological technique, pediatric and adult cadaver studies, and adult live human subject studies, using double-exposed images will be acquired to evaluate the diagnostic image quality of the investigational device versus the predicate device. Target images will be assembled and reviewed in a side-by-side Comparative Evaluation to statistically confirm the findings of this evaluation.

The live human subject portion of this study will be performed on healthy volunteers. Each volunteer will sign an Informed Consent after which they will have two (2) x-rays taken. The first x-ray will follow standard technique using the cleared predicate detector currently in use at the site. Following the first x-ray, we will take one additional x-ray of the same part of the body with one (1) of the investigational detectors. The x-ray from the investigational detector will not be used to diagnose.

If the x-ray obtained by the standard DR x-ray detector shows any unforeseen, unusual or abnormal findings, these findings will be communicated to the subject and their doctor by USPS mail.

Reason for Observational Study Type: There are three (3) physical detectors being used in this study. Each detector is 35 centimeters by 43 centimeters. None of the subjects will given a detector.

结局指标

主要结局

Radlex Scale for Diagnostic Capability Ratings

时间窗: 9 weeks after last x-ray capture

1-Non-diagnostic Unacceptable for diagnostic purposes. Little or no clinically usable diagnostic information (e.g., gross underexposure, system failure or extensive motion artifact). Almost all such imaging should be repeated. 2-Limited Acceptable, with some technical defect (motion artifact, body habitus/poor x-ray penetration, or patient positioning may limit visualization of some body-regions but still adequate for diagnostic purposes). Not as much diagnostic information as is typical for an examination of this type, but likely sufficient. 3-Diagnostic Image quality that would be expected routinely when imaging cooperative patients. 4-Exemplary Good, most adequate for diagnostic purposes. Image quality that can serve as an example that should be emulated.

次要结局

  • Pair Preference Rating(9 weeks after last x-ray capture)
