Clinical Evaluation of CARESTREAM Cone Beam Computed Tomography (CBCT)

2. december 2016 opdateret af: Carestream Health, Inc.
The purpose of this study is to evaluate the 2D and 3D imaging performance of the CARESTREAM Cone Beam Computed Tomography (CBCT) scanner ("investigational device") against the commercially available 2D and 3D predicate devices. The results of this study will be included in a Traditional 510(k) FDA Submission to obtain clearance to market the new CARESTREAM Cone Beam Computed Tomography (CBCT) scanner 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.

Detaljeret beskrivelse

The purpose of this study is to evaluate the 2D and 3D imaging performance of the CARESTREAM Cone Beam Computed Tomography (CBCT) scanner ("investigational device") against the commercially available 2D and 3D predicate devices. The study undertaken will demonstrate the safety and effectiveness of the investigational CARESTREAM Cone Beam Computed Tomography (CBCT) 2D imaging functionality by comparing against the predicate CARESTREAM DRX-1 GOS detector used on adult cadaver specimens to capture the image pairs.

The study will demonstrate the safety and effectiveness of the investigational CARESTREAM Cone Beam Computed Tomography (CBCT) 3D imaging functionality by comparing against the reference PHILLIPS Multi Detector Computed Tomography (MDCT) scanner used on adult cadaver specimens (body part) to capture 3D volumetric exams using the anatomy of both upper and lower extremity specimens. The adult cadaver specimens will receive multiple x-ray exposures using the predicate devices for both 2D and 3D imaging. Target images from cadaver specimens will be reviewed by radiologist readers to rate diagnostic image quality, and the data will be included in a comparative evaluation.

The live human subject portion of the study will be performed on healthy volunteers. Each volunteer will sign an Informed Consent after which will receive only one 3D volumetric exam using the investigational CARESTREAM Cone Beam Computed Tomography (CBCT) scanner. Target images will be reviewed by radiologist readers to rate diagnostic image quality according to a radiologist reader scale applicable to 3D volumetric imaging.

Tidsramme
Radlex Scale for Diagnostic Quality Ratings - 2D Images
Tidsramme: 12 weeks after last image capture
1-1.9-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. 2-2.9-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. 3-3.9-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.
