Another non-contrast technique, phase-contrast angiography, is rarely used in stroke management, but is a valuable tool in detecting venous sinus thrombosis, which often leads to stroke.
Here, using T1 mapping as a truth standard (bright myocardium should have the most contrast present), we show in 250 patients with both immunoglobulin light chain and transthyretin amyloidosis that a new but widely available LGE technique, phase-sensitive inversion recovery, completely solves the nulling problems in amyloidosis.
Two kinds of powerful phase measurement techniques, phase shifting method (PSM) and spatial-carrier method (SCM), were described briefly.
Non-invasive laser detective techniques, Phase Doppler Anemometry (PDA), were used to measure solids holdup and velocity profiles in a three-phase gas liquid solid bubble column.
It is worth mentioning that among data hiding techniques, phase coding tolerates better signal distortion[2].
The initial diameter of electrospray droplets generated using capillaries with outer diameters as small as 12.5 μm to as large as a centimeter have been measured using various techniques, including optical microscopy, flash shadowgraph techniques, phase Doppler techniques, scanning mobility particle sizers, and white light particle counters.
Liu et al. [15] developed a novel encoded-phase technique for phase measuring profilometry, in which the differentially wrapped phases are regarded as codewords.
The present study was designed to validate our noninvasive ultrasonic technique (pulse phase locked loop: PPLL) for measuring intracranial pressure (ICP) waveforms.
This was delivered by a two-phase technique, both phases were CT planned and involved the use of customised blocking on all fields.
Consequently, in the verge of these polymerization techniques, phase-transfer-catalyzed polymerization is one of the recognized and established techniques for the polymerization of alkyl methacrylates in heterogeneous condition using water-soluble initiator.
