3 D Acoustic technology brings new options for 3D printing. Currently, most 3D printing methods rely on photo (light) or thermal activation reactions for precise manipulation of polymers. A new platform technology called direct sound printing (DSP) uses sound waves to create new objects, potentially providing a third option. This process is described in a … Read more
Piezoelectric Dynamic Therapy (PzDT) is a tumor treatment method that utilizes mechanical energy to trigger the polarization of piezoelectric materials. Under the action of ultrasound (US), the immense pressure generated by the collapse of cavitation bubbles serves as a mechanical force source for the piezoelectric sonosensitizer, showing feasible potential. An internal electric field can form … Read more

Chinese Journal of Medical Imaging, 2020, 28(12): 907-911+917 Abstract Objective To explore the ability of the phase-change nanoparticles (Ce6@PFP/PLGA NPs) loaded with the sonosensitizer Chlorin e6 (Ce6) and perfluoropentane (PFP) combined with low-intensity … Read more
iNature Intense noise can damage the spiral ganglion neurons (SGN) in the inner ear, affecting axonal regeneration and leading to noise-induced hearing loss (NIHL). On November 19, 2024, researchers from Fudan University, Bu Wenbo, Ren Dongdong, and Liu Yanyan published a paper titled“Ultrasound-Triggered NO Release to Promote Axonal Regeneration for Noise-Induced Hearing Loss Therapy” in … Read more
Sonodynamic therapy (SDT) is a non-invasive treatment method based on reactive oxygen species (ROS) that interacts with ultrasound (US) activated sonosensitizers and surrounding oxygen and water molecules to produce highly cytotoxic ROS and induce apoptosis. Due to its ability to penetrate deep tissues while causing minimal damage to normal cells, it has significant potential in … Read more
Shandong Provincial Medical Association of Ultrasound Submission Date: 2022-11-01 Corresponding Author: Li Jie, Email: [email protected]. Abstract:Nano-ultrasound contrast agents possess unique features such as liquid-gas phase transition and acoustic cavitation effects, making them important potential carriers for siRNA delivery. Currently, siRNA loading is mainly achieved through electrostatic attraction, requiring the construction of positively charged contrast agents … Read more
Bladder monitoring, including urinary incontinence management and bladder urine volume monitoring, is an important aspect of urological nursing. Urinary incontinence is a common condition affecting the quality of life of over 420 million people globally, and bladder urine volume is a crucial indicator for assessing bladder function and health status. Previous studies have explored non-invasive … Read more
1. Analysis of the Meaning of Ultrasound Diagnosis Ultrasound diagnosis mainly applies the good directionality of ultrasound and its physical characteristics similar to light such as reflection, scattering, attenuation, and the Doppler effect. By utilizing different physical parameters and using various types of ultrasound diagnostic instruments with different scanning methods, ultrasound is emitted into the … Read more
Medical imaging diagnostic equipment characterized by non-invasive, efficient, and intuitive features is one of the most important means for disease screening and auxiliary diagnosis in clinical departments. Imaging data accounts for the largest proportion of medical information, including ultrasound diagnostics, DR (digital X-ray imaging devices), CT (computed tomography), MRI (magnetic resonance imaging), endoscopy, and nuclear … Read more
