Background Non‐melanoma skin cancer (NMSC) is rarely fatal but now the most common malignancy occurring in white populations, accounting for 70% of cost managing cancer. Optical coherence tomography (OCT) has potential to improve diagnostic accuracy and help delineate pre‐surgical margins NMSC. Its widespread clinical acceptance awaits accumulation evidence from studies direct histological comparisons. Method In this study, seventy‐eight subjects presenting with lesions, including 28 NMSCs,...
Abstract To mitigate future global energy challenges, it is vital to utilize natural resources harness sustainable and environmentally‐friendly energy. This paper explores the tribo‐ piezo‐electric functionalities of tomato peel (TP) fabricate a nature‐driven hybrid nanogenerator. Tomato one most cultivated vegetables globally, however, significant amount TP disposed after utilization in food processing industries. The possesses hierarchically placed highly porous structure, which helpful...
This study concerns the radial dynamics of a bubble driven by pulsed ultrasound type generated during extracorporeal shock wave lithotripsy. In particular, numerical model has been used to examine sensitivity oscillations changes in both amplitude driving field and physical conditions fluid surrounding bubble: viscosity, surface tension, temperature gas content. It is shown that, at high negative pressures (p- = 10 MPa) as lithotripsy, timing collapses have considerably reduced initial size...
Blood-spinal cord barrier opening, using focused ultrasound and microbubbles, has the potential to improve drug delivery for treatment of spinal pathologies.Delivering detecting through spine is a challenge clinical translation.We have previously developed short burst, phase keying exposures, which can be used in dual-aperture configuration address scale targeting challenges.Here we demonstrate use these pulses blood-spinal vivo pigs. Methods:The cords Yorkshire pigs (n=8) were targeted...
Objective: To evaluate the effects of low‐intensity ultrasound (LIUS) stimulation on anabolic state human cartilage from patients with osteoarthritis (OA).
The variations of phase velocity and normalized broadband ultrasonic attenuation (nBUA) with porosity were investigated in Polyacetal cuboid bone-mimicking phantoms circular cylindrical pores running normal to the surface along three orthogonal axes. frequency-dependent coefficient porosities from 0% 65.9% measured 0.65 1.10MHz. results showed that at 880kHz decreased linearly porosity, whereas nBUA increased porosity. This study provides a useful insight into relationships between...
The frequency-dependent attenuation and backscatter coefficients were measured in 25 bovine femoral trabecular bone samples from 0.2 to 1.2 MHz. When the average coefficient was fitted a nonlinear power law α(f)=α0+α1fn, exponent n found be 1.65. In contrast, η(f)=η1fn as 3.25. apparent density significantly correlated with parameter α1 (0.2–0.7 MHz: r = 0.852, 0.6–1.2 0.832) well (0.5 0.751, 1.0 0.808).
Abstract Background This work aimed to identify a method achieve improved stone targeting and safety in shockwave lithotripsy by accounting for respiration. Methods We set up an electromotive device simulating renal movement during respiration place artificial stones within the phantom gel, measuring weight changes before after exposure cavitation damage. conducted clinical trials using respiratory masks sensors monitor analyze patient lithotripsy. Results The vitro efficiency of was higher...
The Biot and the modified Biot–Attenborough (MBA) models have been found useful to understand ultrasonic wave propagation in cancellous bone. However, neither of models, as previously applied bone, allows for angular dependence acoustic properties with direction. present study aims account anisotropy by introducing empirical angle-dependent input parameters, defined a highly oriented structure, into MBA models. model is attributed variation elastic moduli skeletal frame respect trabecular...
The present study aims to identify a new recipe for reusable tissue mimicking phantoms that allows the optical visualization of thermal lesions produced in various applications therapeutic ultrasound where mechanisms are important. phantom was made polyacrylamide hydrogel containing nonionic surface-active agent (NiSAA) as temperature-sensitive indicator. Threshold temperature above which lesion is regarded be formed controlled by selecting an NiSAA. In study, three NiSAAs polyoxyethylene...
