A method for producing the x-ray spectra of different anode/filter combinations is proposed. The performance of several mammographic spectra, produced by both existing and theoretical anode materials, is evaluated, with respect to their dose and subject contrast characteristics, using a Monte Carlo ...

In contrast to state-of-the-art femur models for predicting bone strength, our numerical framework also incorporates a description of the subject-specific fracture energy into the models. This aspect is expected to be highly relevant in the analysis of osteoporotic patients. Additionally, the ...
johnsoniae strain showed cell population migration at the colony's edge, in stark contrast to the mutant strains, where only individual cells, not populations, displayed migration. Pep25 and lbp26, according to the findings of this study, are influential in the colony dispersion of F. collinsii...
Overall image quality of most CBCTA was deemed suitable for diagnostic use in contrast to a considerable amount of non-diagnostic MDCTA examinations (38.8%). The depiction of bone, cartilage and ligaments in MDCTA with any form of dose reduction was inferior to any CBCTA scan with at least...

In a known X-ray mammography machine, generally, the X-ray transmittance ratios obtained due to the difference in the tissue density of a subject are formed into an image of a subject internal structure. In contrast, a photoacoustic mammography machine is capable of estimating the density and ...
