A novel optical imaging technique called sonoluminescent tomography was developed for cross-sectional imaging of strongly scattering media noninvasively. Sonoluminescence, which was generated internally in the medium by cw ultrasound, was used to produce a two-dimensional image of an object embedded in a scattering medium by means of raster scanning the medium. The image had a high contrast and...
For two main reasons, dermatology is one of the later medical disciplines to use imaging techniques: 1) skin lesions are readily visible to the naked eye or through a magnifying glass, allowing clinical diagnosis with no invasive examination, 2) skin lesions can easily be biopsied or removed for histological study. This approach has therefore remained the basis of clinicopathological diagnosis ...
myelodysplastic syndromes (mdss) are a clonal bone marrow (bm) disease characterized by ineffective hematopoiesis, dysplastic maturation and progression to acute myeloid leukemia (aml). methylation silencing of hrk has been found in several human malignancies. in this study, we explored the association of hrk methylation status with its expression, clinical parameters and mds subtypes in mds pa...
in the research, six degrees of freedom hexapod parallel machine tool is studied and investigated. jacobian matrix is developed by cinematic relations differentiation and using weighted coefficient method, dimensional analysis operation is carried out on jacobian matrix. geometric parameters of cartesian robot workspace are optimized, considering a minimum allowable rotation about three axes, a...
