Real-time X-ray microradiographic imaging and image correlation for local strain mapping in single trabecula under mechanical load
Popis výsledku v původním jazyce
X-ray microradiography was used to quantify the strains in loaded human trabecula. Samples of isolated trabeculae from human proximal femur were extracted and glued in a loading machine specially designed for testing of small specimens. The samples weretested in tension and three-point bending until complete fracture occured. Real-time microradiography in conjunction with digital image correlation has been used. The samples were irradiated continuously by X-rays. Radiographs were acquired using 0.25s exposure time with hybrid single-photon counting silicon pixel detector Medipix2. Designed loading device enables for precise control of the applied displacement which is important for the post-yield behavior assessment. Tested experimental setup enablesto combine micromechanical testing of the basic building block of trabecular bone with time-lapse X-ray radiography to assess the mechanical properties of single human trabecula and capture the softening curve with sufficient precision.
