چکیده
This paper presents an absolute X-ray photon energy measurement method that uses a Bond diffractometer. The proposed system enables the prompt and rapid in situ of energies over wide range. diffractometer reference silicon single-crystal plate highly accurate angle encoder called SelfA. performance is evaluated by repeatedly measuring first excited state potassium-40 nuclide. excitation determined as 29829.39 (6) eV, this one order magnitude more than previous measurement. estimated uncertainty was 0.7 p.p.m. standard deviation maximum observed 2

Comparison of Singh index accuracy and dual energy X-ray absorptiometry bone mineral density measurement for evaluating osteoporosis
Background: The Singh index is an inexpensive simple method to evaluate bone density, commonly used to assess osteoporosis is based on the radiological appearance of the trabecular bone structure of the proximal femur on a plain antero-posterior (AP) radiograph. The purpose of this study was to compare between Singh index and bone mineral density measurement using dual energy X-ray abs...
متن کاملFootprint as an alternative to X-ray in hallux valgus angle measurement
Background: X- ray images provide accurate and reliable data in different foot pathologies. However, the accompanied complications will limit its use for epidemiological studies and research purposes, especially in children. Therefore, simple, accessible, and cost- effective methods such as footprint, with a good correlation with x-ray images, are needed to help diagnose different foot pa...
متن کاملHigh energy x-ray phase contrast CT using glancing-angle grating interferometers.
PURPOSE The authors present initial progress toward a clinically compatible x-ray phase contrast CT system, using glancing-angle x-ray grating interferometry to provide high contrast soft tissue images at estimated by computer simulation dose levels comparable to conventional absorption based CT. METHODS DPC-CT scans of a joint phantom and of soft tissues were performed in order to answer sev...
متن کاملDetermining Measurement Error for Bohler's Angle and the Effect of X-Ray Obliquity on Accuracy.
BACKGROUND Bohler's angle (BA) is the most commonly utilized radiographic measurement in the study of calcaneus fractures and has been shown to be prognostic in nature. Therefore, it is critical that the measurement of BA be accurate as both therapeutic and prognostic information relies on it. Oblique lateral radiographs can be a cause of error in BA measurements. However, measurement error and...
متن کاملAbsolute Intramolecular Distance Measurements with Angstrom-Resolution Using Anomalous Small-Angle X-ray Scattering.
Accurate determination of molecular distances is fundamental to understanding the structure, dynamics, and conformational ensembles of biological macromolecules. Here we present a method to determine the full distance distribution between small (∼7 Å radius) gold labels attached to macromolecules with very high-precision (≤1 Å) and on an absolute distance scale. Our method uses anomalous small-...
