Ultrasound is a safe, non-invasive technique that can be used in various medical applications to improve patient quality of life. In this paper we discuss the current status of two ultrasound-based medical projects. The techniques we are developing can in the future be applied to medical monitoring in rural or space settings. Urinary incontinence affects a large percentage of the population. We...

intense the granular deposits, the slower and more persistent the course of the disease, whereas a diffuse pattern of pigmentation with an absence of globules or dots was associated with earlier resolution.9,10 In our patient we observed a mottled pattern formed by clusters of numerous brown dots and globules and, as predicted, the course clinical was slow and the condition persisted for a year...

OBJECTIVE To compare pregnancy rate, cost effectiveness, patients effort, related stress, and the ovarian hyperstimulation syndrome (OHSS) rate, between patients monitored for ovarian hyperstimulation using a combination of ultrasound and hormonal determination (combination protocol), in contrast to applying ultrasound only, in in vitro fertilization and embryo transfer (IVF ET). METHOD This ...

Computational Methods of Ultrasound Wave Propagation in Healing Long Bones D. I. Fotiadis1 Summary Quantitative ultrasound has attracted significant interest in the evaluation of bone fracture healing. Animal and clinical studies have demonstrated that the propagation velocity across fractured bones can be used as an indicator of healing. Researchers have recently employed computational methods...

The harmonic motion imaging (HMI) technique for simultaneous monitoring and generation of ultrasound therapy using two separate focused ultrasound transducer elements was previously demonstrated. In this study, a new HMI technique is described that images tissue displacement induced by a harmonic radiation force using a single focused-ultrasound element. A wave propagation simulation model firs...

Complete bicornuate uterus is a type of Mullerian duct deformity, resulting from abnormal duct fusion. Similar to other Mullerian anomalies, bicornuate uterus is associated with specific complications during possible pregnancies. While various studies have reported successful deliveries in a bicornuate uterus, it might be accompanied with various complications, ranging from preterm labor to mor...

This study evaluated the effectiveness of ultrasound, color Doppler imaging and conventional radiography in monitoring the post-surgical healing of periapical lesions of endodontic origin. Fifteen patients who underwent periapical surgery for endodontic pathology were randomly selected. In all patients, periapical lesions were evaluated preoperatively using ultrasound, color Doppler imaging and...

Interstitial ultrasound applicators have been proposed for treating deep-seated tumours that cannot be reached with extra-corporeal high-intensity focused ultrasound. In addition, interstitial ultrasound offers several advantages compared with conventional ablation technology (radiofrequency, microwaves, cryotherapy) in terms of penetration, speed of coagulation, ability to direct and control t...

Patients, methods, and results Episodes of acute graft dysfunction (increase in creatinine concentrations of ¢30 [imol/l between two successive measurements) occurring during January 1984 to February 1988 were studied retrospectively. Only patients who underwent a Tru-Cut biopsy of their transplant were included so that histological evidence was available. Patients with a proved urinary tract i...

Poor recovery after systemic tissue plasminogen activator (tPA) therapy could result from the initial severity of ischemic insult and slow and incomplete thrombolysis. Persisting arterial occlusions can be identified at bedside using portable diagnostic ultrasound by detecting residual flow signals around the thrombus (thrombolysis in brain ischemia [TIBI] flow grades). A narrow pulsed ultrasou...
