To check or to prevent failures in ultrasound medical systems, some tests should be scheduled for both clinical suitability and technical functionality evaluation: among them, image quality assurance tests performed by technicians through ultrasound phantoms are widespread today and their results depend on issues related to scanner settings as well as phantom features and operator experience. I...

The purpose of this work is to examine the possibility using multi-angle conventional ultrasound B-mode scanning in efficient 3-D imaging. In paper, volume an object reconstructed from vertical projections registered at fixed angular positions multi-element linear ultrasonic probe rotated relation submerged water. possible configurations are: lateral, top or bottom. lateral configuration, acqui...

background: with the technical development, ultrasound tends to overpass its limits and to become the main investigation tool even for situations when it was traditionally considered second best. it is more convenient both for patient and doctor, less expensive and has real diagnostic value. objective: the present paper, and its graphic back-up, are intended as a visual testimony of the fact th...

The influence of mechano-ultrasonic activation (MUA) and nano-additives (carbon nanotubes-CNT) on the interaction pathway nickel–aluminum powder mixture at high heating rates was investigated. optimum conditions activation, along with phase structure formation peculiarities nickel–aluminum–carbon nanotubes mixtures by thermal analysis method, so-called high-speed temperature scanner (HSTS), wer...

there exist a number of factors that affect the quality laser scanner. in other words, the accuracy of a terrestrial scanner is limited extensively by systematic errors and thus must be calibrated. indeed, calibration is a prerequisite for obtaining 3d precise and reliable data from point clouds. until now, several models have been proposed to improve the accuracy of laser scanner data, most of...

The twinkling artifact has been known to specialists in ultrasound diagnostics since 1996. However, until now there is no understanding of the reasons for its appearance, and place application diagnostics. Material methods. Electronic databases (PubMed, E-library, Web Science) were searched studies using keyword – “twinkling artifact”. scientific publications on Doppler from moment first report...
