Mirena in Two-Dimensional Ultrasound

Three-dimensional Flexible Needle Streering Using Two-dimensional Ultrasound Images

One of the most commonly performed minimally invasive surgical procedures is needle insertion. Such needle insertions are often performed either for diagnosis (e.g., biopsies) or therapy (e.g., brachytherapy), both of which require accurate needle placement. These procedures are frequently performed under ultrasound image-guidance which provides visual feedback. Clinicians usually use rigid bev...

Flash Artifact Suppression in Two-Dimensional Ultrasound Imaging

Can hiatal ballooning be determined by two-dimensional translabial ultrasound?

INTRODUCTION Imaging of the levator hiatus, the largest potential hernial portal in the human body, requires axial plane imaging by ultrasound or magnetic resonance imaging. The aim of this study is to determine whether 2D translabial ultrasound may identify excessive hiatal distensibility by measuring the anteroposterior (AP) diameter of the hiatus. This may become clinically relevant for risk...

Two dimensional ultrasound scanning of excised brains--I. Normal anatomy.

-This study demonstrated techniques for visualization of detailed brain anatomy with two dimensional ultrasound. The use of large aperture focused ultrasound transceivers appears to be essential for displaying the outlines of thalamus, internal capsule and substantial nigra in addition to those of the ventricles. The ability to vary grey scale and edge enhancement using either linear or logarit...

Two-dimensional Blind Deconvolution of Medical Ultrasound Images

This paper uses a new ultrasound tissue model to propose an ultrasound image deconvolution algorithm for improving the quality of ultrasound images. This model incorporates random fluctuations of the tissue signal within the received ultrasound RF echo signal, which has not been considered in the existing ultrasound imaging algorithms. To deal with the tissue image formation and noise reduction...
