1.1 Statement of the Problem Endo-neuro-sonography (ENS) has gained special attention in recent years. Its major advantages over traditional brain surgery are that it is a minimally invasive surgical technique and the endoscopic camera and ultrasound images provide useful information. Ultrasound images are inexpensive compared to tomographic and resonance magnetic images (which are very hard to...

The use of bedside ultrasound by emergency physicians has dramatically increased over the past twelve years. Its use has led to increased speed of diagnosis, expedited disposition, and improved quality of emergency care. While there are eight primary applications of emergency ultrasound, its increasing presence in the emergency department (ED) has led to broader utilization of this diagnostic m...

Dear Editor, We read with interest the review by Touw et al. and the related editorial, which warmly warrant the use of ultrasound for internists. We would respectfully remark that an adequate comprehensive training is needed to teach and learn the uses and limitations of ultrasound. An optimal ultrasound examination of a dyspnoeic patient should be done in sitting position, since it is unlikel...

Nosocomial infections are posing an increasingly serious problem in the hospital setting. With the increasing use of ultrasound in medical diagnosis, there is the potential for transmission of nosocomial infections via the ultrasound transducer and coupling gel. We evaluated the use of different membranes (three types of commercially available household cling film, condom, surgical glove and Op...

We present a system for the interactive simulation of ultrasound guided peripheral nerve blocks using a Microsoft Kinect®. The system performs motion tracking of both the ultrasound probe and the nerve block needle. Software generates synthetic ultrasound images from previously captured ultrasound images. Details of the software elements in the system are described. Some of the current challeng...

We present a method to register a pre-operative 3D CT or MR volume to a set of intra-operative tracked ultrasound images. Our aim is to allow the transfer of information from pre-operative modalities to ultrasound images to aid needle placement during thermal ablation of liver metastases. Spatial correspondence between ultrasound slices is achieved by tracking the probe using a Polaris optical ...

In ultrasound, a high frequency sound wave is launched into the eye with the help of a probe and the sound wave is reflected from different boundaries between microstructures. However, the OCT uses light rather than ultrasound. The speed of the light is almost a million times faster than sound and this difference allows the measurement of structures with resolution of =10 μ compared to 100μ sca...

We have constructed a nearly real-time combined imager suitable for simultaneous ultrasound and near infrared (NIR) diffusive light imaging and co-registration. The imager consists of a combined probe and associated electronics for data acquisition. A two-dimensional ultrasound array occupies the center of the combined probe, while 12 dual wavelength laser source fibers (780 nm and 830 nm) and ...

The purpose of this work is to examine the possibility using multi-angle conventional ultrasound B-mode scanning in efficient 3-D imaging. In paper, volume an object reconstructed from vertical projections registered at fixed angular positions multi-element linear ultrasonic probe rotated relation submerged water. possible configurations are: lateral, top or bottom. lateral configuration, acqui...

Anesthetizing the lumbar plexus at its origin facilitates a more "complete" psoas compartment block compared to peripheral approaches. It is usually performed using surface anatomical landmarks, and the site for local anesthetic injection is confirmed by observing quadriceps muscle contraction to peripheral nerve stimulation. Ultrasound may provide guidance alone or together with the aid of ner...
