| Fluoro-Test Tool. |
 |
Introduction The Fluoro-Test Tool*1 (Model 07-645) is a fluoroscopic contrast resolution device that employs a target arrangement designed to reduce ambiguity and difficulty associated with employing a sequential array of targets with small differences in contrast between adjacent targets. It is designed to yield a quantitative assessment of fluoroscopic threshold contrast. With the Fluoro-Test target plates, the user focuses on a subset of three targets at a given time. In each subset or column, large differences (approx. 3%) are present between adjacent targets and it is easy to decide if a target is visualized or not. The threshold contrast for a plate is the lowest of the values observed for the three columns of targets, and a contrast resolution precision of 0.5% is obtained by the sequential use of the two plates. When imaged at 80 kVp with 2.0 mm of Cu beam attenuation, the targets of Plate A range in contrast from 1 to 8% in 1% increments. Likewise, the targets of Plate B range from 0.5% to 7.5%. Tables of target contrast versus kVp permit the user to determine target contrast (and therefore threshold contrast resolution) at other fluoroscopic tube potentials. The development of the Fluoro-Test Tool is based on the work of Wagner, Barnes and Wu.1 Specifications Dimensions: The test tool consists of two 6 x 6 x 0.25 in (6.1 mm) thick aluminum plates, with each plate containing an array of 1.1 cm targets of varying contrast. Also included are three 6 in x 6 in x 1 mm thick copper attenuator sheets. Weight: 3.15 lb (1.42 kg) |
| R/F Quality Control Phantom. |
 |
Introduction The R/F QC Phantom is designed to provide the diagnostic radiologic technologist with an accurate, easy-to-use tool for evaluating the image quality and performance of standard diagnostic radiographic and fluoroscopic imaging systems. Applications For fine-tuning of radiographic and fluoroscopic imaging systems, it is recommended that the phantom be imaged at least monthly on all radiographic and fluoroscopic equipment. To attain the most accurate, up-to-date quality control information, a daily or weekly frequency is preferable. When used daily, the R/F QC Phantom will allow the technologist to quickly determine whether the equipment is functioning correctly. This easy-to-use phantom allows the user to complete the suggested protocol in approximately 5 minutes or less, when used on a standard R/F system. Once the phantom is imaged, simply graph the results to determine any trends that may indicate a degradation of imaging system performance, such as a steady but slow change in the fluoro kVp or in the radiographic mAs. |
