applying 2d algorithms for inverting the potential field data is more useful and efficient than their 3d counterparts, whenever the geologic situation permits. this is because the computation time is less and modeling the subsurface is easier. in this paper we present a 2d inversion algorithm for interpreting gravity data by employing a set of constraints including minimum distance, smoothness,...

background: ratio of second and fourth digit (2d:4d) is known to be germane in analyzing utero concentrations of testosterone and estrogen in human and other vertebrates. 2d:4d had been linked several traits like athletes’ abilities, reproductive success, risk of cancer and cardiovascular disease (cvd). metabolic syndrome (mets) is a clustering of several cardiovascular risk factors. waist ci...

Point-of-care ultrasonography (POCUS) is a useful imaging technique for the emergency medicine (EM) physician. Because of its growing use in EM, this article will summarize the historical development, the scope of practice, and some evidence supporting the current applications of POCUS in the adult emergency department. Bedside ultrasonography in the emergency department shares clinical applica...

BACKGROUND Presenting signs and symptoms of pulmonary embolism (PE) are nonspecific, favoring a large use of second-line diagnostic tests such as multidetector CT pulmonary angiography (MCTPA), thus exposing patients to high-dose radiation and to potential serious complications. We investigated the diagnostic performance of multiorgan ultrasonography (lung, heart, and leg vein ultrasonography) ...

--The ultrasound imaging is very popular to diagnosis the disease because of its non-invasive nature. The ultrasound imaging slowly produces low quality images due to the presence of spackle noise and wave interferences. There are several algorithms to be proposed for the segmentation of ultrasound carotid artery images but it requires a certain limit of user interaction. The pixel in an image ...

56 Introduction Recent advances in prenatal diagnosis and therapy has been made possible with the invention of newer imaging modalities including 3D and 4D ultrasound. Two dimensional ultrasound remains the method by which most fetal structural abnormalities are screened and diagnosed, however 3D and 4D are being used increasingly for the examination of the human fetus. Two dimensional scanning...

Compared to other medical breast imaging techniques, ultrasonic imaging is more attractive due to its relatively low cost and wide clinical use. This study is concerned with clinical amplitude/velocity reconstruction imaging (CARI) ultrasonography for accurately detecting breast cancer using two acoustic properties: the sound speed and the attenuation. Bioacoustic modeling is used to describe u...
