Needle placement under ultrasound can be achieved by two different approaches, namely, an In-plane and Out-of-plane technique. Each of these approaches offers its own advantages and challenges. Depending on different factors that include body habitus, anatomic considerations, and needle trajectories ...
We propose a procedure for crack characterisation (depth, angle) that considers transmission alongside measurements of both the in-plane and out-of-plane velocity components of the Rayleigh wave in the near-field of a defect, where the signal is enhanced due to constructive interference of ...
BackgroundA long-axis in-plane (LA-IP) approach and a short-axis out-of-plane (SA-OOP) approach are the two main approaches used in ultrasound (US)-guided vascular catheterization. However, the efficacy and safety of these approaches remain controversial. Therefore, we performed this meta-ana...
The aim of this study was to assess the out-of-plane versus the in-plane approaches for the interscalene brachial plexus block, as regards the performance time, the onset, the progression and the recovery of sensory block, the onset and progression of the motor block as well as, the postop...
The manipulation of light emitted by two-dimensional semiconductors grounds forthcoming technologies in the field of on-chip communications. However, these technologies require from the so elusive out-of-plane photon sources to achieve an efficient coupl
Subsequently, the ultrasound probe was moved 2–3 cm laterally to locate the hyperechogenicity of the T8 transverse process and identify the erector spinae muscle. Using an in-plane technique, a 21-G needle was advanced in a cranio-caudal direction until the tip of the needle reached the ...
Due to their 2D nature and unlike traditional bulk semiconductors, TMD monolayers can be easily locally strained, for example, via deformation in the out-of-plane direction11,12. Since the associated excitonic properties are highly strain-dependent, this results in effective local potentials for exci...
Objective To observe the efficacy of ultrasound-guided transversus abdominis plane(TAP)block for postoperative analgesia in cesarean delivery under general anesthesia.Methods Forty patients,American Society of Anesthetists(ASA)gradeⅠorⅡ,scheduled for cesarean delivery under general anesthesia were randomly ...
The blood–brain barrier (BBB) prevents harmful toxins from entering brain but can also inhibit therapeutic molecules designed to treat neurodegenerative diseases. Focused ultrasound (FUS) combined with microbubbles can enhance permeability of BBB and is
Transparent ultrasound transducers (TUTs) can seamlessly integrate optical and ultrasound components, but acoustic impedance mismatch prohibits existing TUTs from being practical substitutes for conventional opaque ultrasound transducers. Here, we propos
