Background/introduction The Kona Medical Surround SoundTM System is a fully non-invasive system for renal denervation which employs ultrasound based imaging for targeting and tracking as well as a phased array therapeutic ultrasound transducer. To date, 69 patients have been treated under three different protocols (WAVE I, WAVE II, and WAVE III). Follow up ranges from 3 months to over 2 years. ...

AANA Journal  June 2011  Vol. 79, No. 3 209 Sonography addresses a variety of concerns, such as patient safety and comfort, cost-effectiveness, time to complete a procedure, and success rates associated with invasive anesthesia procedures. Ultrasound guidance is commonly being used for the placement of nerve blocks, placement of peripheral and central lines, and arterial catheterization. Rece...

Background: Endoscopic ultrasound (EUS)-guided radiofrequency ablation (RFA) is a novel modality in the treatment of solid tumours. The aim study to evaluate technical feasibility, safety and efficacy multiple-round EUS-RFA with low power for unresectable pancreatic cancer.

Background Surgical robotics, machine learning for medical imaging, and focused ultrasound surgery (FUS) have the same long term goals: reducing invasiveness of therapies, augmenting the number of treatable diseases and, more in general, helping the healthcare system in terms of costs and benefits. Potentials from synergies among these fields are undeniable; cross-fertilization are expected to ...

In a fetus with supraventricular tachycardia (SVT) and cardiac failure, normal sinus rhythm (NSR) was restored with maternal digoxin therapy at 26 weeks' gestation. The diagnosis of cardiac failure was based on ultrasound evidence of ascites and scalp edema. Cardiac failure was attributed to the persistent SVT. The infant remained in NSR and was delivered at 36 weeks' gestation because of persi...

Background/introduction MRI-guided transurethral ultrasound ablation (TULSA) is a new minimally-invasive modality for the treatment of prostate cancer, which aims to provide local disease control with low morbidity. A transurethral ultrasound device generates a continuous volume of thermal coagulation that is shaped precisely to the prostate using realtime MR thermometry and active temperature ...

While high-intensity focused ultrasound has been used for some time in the management of uterine fibroids, its effectiveness and safety in managing adenomyosis is less well established. A literature review was performed of all eligible reports using this modality as a treatment for adenomyosis. Relevant publications were obtained from the PubMed electronic database from inception through March ...

Among the two distinct medical ultrasound applications, diagnostic and therapeutic ultrasound, application is widely used for non-invasive imaging to acquire both anatomical functional information from inside body. The advantages of are safety due absence ionizing radiation, patient-friendly convenience, portability compared with other tools. Even though considered safe, beam could interact tis...

This paper presents a new robotic mechanism for ultrasound imaging. The device is placed on a patient's body by an operator, and an ultrasound expert controls the motions of the device to obtain ultrasound images. The paper focuses on the robotic mechanism that performs ultrasound imaging. The design of the mechanism is based on two approaches to produce center of motion for an ultrasound probe...

The ability of ultrasound to penetrate deep into tissue and interact with human tissues via thermal and mechanical mechanisms has expanded its various therapeutic applications. In the 1950s, low power (1 MHz) ultrasound began being used for physical therapy of tendinitis or bursitis and, in the 1980s, high pressure amplitude shockwaves were used for kidney stone destruction in lithotripsy. Sinc...
