Just like radar, ultrasound volumes are typically acquired in a grid that diverges as you move away from the transducer into the body. To give you an idea of the nature of ultrasound images, Figure shows a 2D ultrasound image of a fetus. You can imagine the 3D version of the ultrasound volume: a truncated pyramid or a cone, similar to Figure b. Figure A 2D Ultrasound Image of a Fetal Head. Three-dimensional ultrasound data is acquired by an ultrasound scanner and stored in its local memory as a 3D array.  "High-Quality Volume Graphics on Consumer PC Hardware." Course Notes 42, SIGGRAPH Available online at www.- ~jmk/sigg_crs_02/course_42/course_42_notes_www.- Open platform (OP) ultrasound systems are aimed primarily at the research community. They have been at the forefront of the development of synthetic aperture, plane wave, shear wave elastography, and vector flow imaging. Such platforms are driven by a need for broad flexibility of parameters that are normally preset or fixed within clinical scanners.  Looking to the future, mobile, ultrafast ultrasound hardware technologies create immense opportunities to expand the existing knowledge of human and animal movement. View. Show abstract. It is well known that clinical ultrasound scanners are ill-suited for the realization of a new imaging mode [19]. Pleural effusion volume (ultrasound). Andrew Murphy ◉ and Dr David Carroll ◉ et al. Measurement of a pleural effusion volume with point-of-care ultrasonography may be a useful tool for intensivists and is an active area of research in critical care 7. In controlled settings ultrasound may detect constitutive pleural fluid, can reliably detect effusions >20mL in clinical settings, and may approach the sensitivity and specificity of computed tomography. Assessment of pleural effusions by ultrasound has historically been semi-quantitative, a gestalt of whether the effusion appears minimal, mil.
