Metamaterials allow ultrasound to penetrate bone and metal

Researchers at North Carolina State University have designed complementary metamaterials that will aid medical professionals and engineers in diagnosing problems under the skin. These metamaterials are structured to account for so-called “aberrating layers” that block or distort the acoustic waves used in ultrasounds, making it possible to now conduct ultrasounds of a person’s head or an airplane’s wing – among other things.

Ultrasound-Guided Vascular Access: In-Plane Approach

va-in-planeThe in-plane or long access approach is the technique used to allow visualization of the entire needle when performing ultrasound-guided vascular access.
The transducer is positioned in a long axis over the selected vein.  The vessel is visualized straight across the screen.  The needle is placed at the center of the transducer in-line with the ultrasound beam and the trajectory of the vessel with the bevel up.

The transducer is held stationary with the non-dominant hand while advancing the needle using the dominant hand.

Word of the Day – Hypoechoic

hypoechoic_ renal-cortexHypoechoic – not as bright as surrounding tissue, weaker echoes. In ultrasonography it describes tissues or structures that reflect relatively few of the ultrasound waves directed at them.
