He had developed a technique, intravascular ultrasound, that involves threading a tiny ultrasound camera into arteries and directly observing plaques and precisely measuring their size.
To obtain such invaluable information, satisfactory techniques for microscopically capturing statistically representative blob samples and measuring their size distribution have been devised.
Aqueous lipid suspensions surrounding a hydrophone were exposed to various intensities of ultrasound and hydrostatic pressures before measuring their size distribution with dynamic light scattering.
The problem of detecting low CNR defects and of measuring their size has instead received attention within the more general automatic weld inspection analysis field.
The NPs were characterized by measuring their size, using a Coulter N5 Submicron Particle Sizer (Coulter Corporation, Miami, FL) at 90°, and charge, using a Malvern Zeta Sizer 2000 (Malvern Instruments, Southborough, MA).
The researchers measured their sizes and velocities only in extremely calm conditions, so the wind that often accompanies rain could not skew the data.
Based on the 3D morphologies of the liver sinusoids (Fig. 1E and 1F), we were able to count the number of fenestrations and measure their sizes statistically.
The binary star, designated M31VJ00443799+4129236, has two luminous and hot blue stars of types O and B. By studying the eclipses of the stars, which occur every 3.54969 days, astronomers were able to measure their sizes.
We first identified the connected components of the two networks and measured their sizes using the clusters function of the R igraph package [32], [33].
The assay is also quantitative, and PCR is employed to verify expansions and to measure their sizes.
