This paper describes a simple microfluidic sorting system that can perform size profiling and continuous mass-dependent separation of particles through combined use gravity (1 g) hydrodynamic flows capable rapidly amplifying sedimentation-based between particles. Operation the device relies on two transport processes: (i) initial focusing in microchannel oriented parallel to (ii) subsequent sample where positional difference with different mass generated by sedimentation is further amplified...
The vaporization of a superheated droplet emulsion into gas bubbles using ultrasound-termed acoustic (ADV)-has potential therapeutic applications in embolotherapy and drug delivery. optimization ADV for can be enhanced by understanding the physical mechanisms underlying ADV, which are currently not clearly elucidated. Acoustic cavitation is one possible mechanism. This paper investigates relationship between inertial (IC) thresholds (measured as peak rarefactional pressures) studying...
This paper examines the vaporization of individual dodecafluoropentane droplets by application single ultrasonic tone bursts. High speed video microscopy was used to monitor in a flow tube, while focused, element transducer operating at 3, 4, or 10 MHz aimed intersection acoustical and optical beams. A highly dilute droplet emulsion injected, were positioned two foci. Phase transitions produced rarefactional pressures as low 4 MPa 3 using single, 3.25 μs During acoustic irradiation, showed...
In a study involving 10 different sites, independent results of measurements ultrasonic properties on equivalent tissue-mimicking samples are reported and compared. The measured were propagation speed, attenuation coefficients, backscatter coefficients. Reasonably good agreement exists for but less satisfactory found speeds. As anticipated, was not impressive in the case Results four sites agreed rather well both absolute values frequency dependence, from other lower by as much an order...
The crestal bone level and soft tissue dimension are essential for periodontal diagnosis phenotype determination; yet, existing measurement methods have limitations. aim of this clinical study was to evaluate the correlation accuracy ultrasound in measuring dimensions, compared direct cone-beam computed tomography (CBCT) methods.A 24-MHz probe prototype, specifically designed intraoral use, employed. Periodontal dimensions levels were measured at 40 teeth 20 single missing tooth gaps from...
ABSTRACT Aim To describe the application of power Doppler Ultrasonography (US) for evaluating blood flow at implant and palatal donor sites following soft tissue augmentation with connective graft (CTG). Materials Methods Five patients exhibiting a peri‐implant dehiscence received treatment coronally advanced flap corresponding CTG. Power US was used assessing volume baseline, 1 week, month, 6 months 12 post‐surgery blood‐flow dynamics sites. The speed‐weighted power‐weighted colour pixel...
Objectives To discuss challenges in assessing hepatic steatosis using ultrasound hepatorenal index (HRI). Methods We retrospectively analyzed HRI and liver magnetic resonance imaging‐based proton density fat fraction (MRI‐PDFF) 134 adult participants (53 men 81 women, mean age 55 years). The diagnostic performance of for determining was tested by the area under receiver operating characteristic curve (AUROC) MRI‐PDFF as reference. Regression plots were employed to compare sampling sites...
The objective was to determine whether a transpulmonary droplet emulsion (90%, <6 μm diameter) could be used form large gas bubbles (>30 μm) temporarily in vivo. Such occlude targeted capillary bed when number density. Alternatively, for very sparse population of droplets, the resulting serve as point beacons phase aberration corrections ultrasonic imaging. Gas can made vivo by acoustic vaporization (ADV) injected, superheated, dodecafluoropentane droplets. Droplets vaporize an field whose...
The use of superheated liquid perfluorocarbon droplets encased in albumin shells has been proposed as a minimally invasive alternative to current treatment cancer by means occlusion therapy. In response an applied acoustic field, these droplets, which are small enough pass through capillaries, vaporize into large gas bubbles that subsequently lodge the vasculature. This technique, known droplet vaporization (ADV) shown successfully reduce blood flow vivo, but for situ conditions where...
Acoustic droplet vaporization in a rigid tube at body temperature was investigated experimentally using an ultra-high speed camera. This study motivated by gas embolotherapy, developmental cancer treatment which microbubbles that are selectively formed acoustically vaporizing liquid droplets vivo used to occlude tumor blood flow. The evolution of acoustic analyzed and four-stage empirical curve fit the growth. Viscous resistance from shown dampen oscillations even though bubble diameter...
Ultrasound imaging has potential to complement radiographic modalities in implant and oral surgery given that it is non-ionizing provides instantaneous images of anatomical structures. For application dental imaging, its qualities are dependent on ability accurately capture these complex Therefore, the aim this feasibility study was investigate ultrasound image soft tissue, hard tissue surface topography specific vital A clinical scanner, paired with two 14-MHz transducers different sizes...
Facial crestal bone level and dimension determine function esthetics of dentition dental implants. We have previously demonstrated that ultrasound can identify bony soft tissue structures in the oral cavity.

The aim of this study was to examine the accuracy high-resolution, 3-dimensional ultrasound measure peri-implant dimensions.A 25-MHz probe prototype used scan tissues 17 from seven fresh human cadavers. Four ultrasonic measurements were made as follows: level/thickness, mucosal level/thickness. readings statistically compared cone beam computed tomography (CBCT) and/or...
Ultrasonography has shown its promising diagnostic value in dental implant imaging research the three treatment phases, namely, planning, intraoperative, and postoperative phase. With increasing awareness of peri-implant diseases a lack an efficient method, aim is to propose ultrasound as potential solution by providing detailed scanning protocol case demonstration.Ultrasound device specification setup for optimizing tissue was described. Two useful modes, viz. B-mode color flow, were...

Color flow ultrasonography has played a crucial role in medicine for its ability to assess dynamic tissue perfusion and blood variations as an indicator of pathologic condition. While this feature ultrasound is routinely employed various medical fields, intraoral application the assessment at diseased versus healthy dental implants never been explored. We tested hypothesis that quantified power Doppler correlates with clinically assessed inflammation implants. Specifically, we designed...
