Brief summary: The purpose of this clinical study is to evaluate the imaging performance of the Carestream PRO 3543 Detector and Carestream PRO 3543C Detector (referred to as the "investigational devices") as compared to the currently marketed Carestream DRX-1 Detector (referred to as the "predicate device"). Both detectors are flat panel digital imaging devices. 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.

Detailed description: The purpose of this clinical study is to evaluate the imaging performance of the investigational devices as compared to the currently marketed predicate device. The evaluation will consist primarily of comparing the diagnostic image quality of pediatric and adult cadaver studies and adult live human subject studies acquired under the same exposure technique.

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. All subjects are healthy volunteers recruited by flyer. All subjects will be imaged with the same predicate detector and one (1) of the investigational detectors.

Eligibility criteria: Inclusion Criteria:

* X-ray images of nearly identical positioning and exposure
* No visible image artifacts
* Subject 21 years or older
* Subject has provided informed consent
* Subject is in good general health (is able to be still to reduce the potential of motion in the images)
* Subject is able to stand for two (2) x-rays

Exclusion Criteria:

* Images that are not clinically acceptable for clinical radiographic reading as determined by the Principal Investigator.
