Acoustics
Research News and Information
Definition of 'Acoustics'The branch of physics that deals with sound and sound waves. In medicine it is often applied in procedures in speech and hearing studies. With regard to the environment, it refers to the characteristics of a room, auditorium, theatre, building, etc. that determines the audibility or fidelity of sounds in it. (From Random House Unabridged Dictionary, 2d ed) Common names: Acoustics; Acoustic |

Gold nanoparticles as a contrast agent for in vivo tumor imaging with photoacoustic tomography.
Sep 2009 
Photoacoustic tomography (PAT) is a rapidly emerging non-invasive imaging technology that integrates the merits of high optical contrast with high ultrasound resolution. The ability to quantitatively and non-invasively image nanoparticles has ... Read more...
Implantation of an atelocollagen sheet for the treatment of vocal fold scarring and sulcus vocalis.
30 Aug 2009 OBJECTIVES: The management of vocal fold scarring and sulcus vocalis is challenging. These disorders are thought to be fibroplastic anomalies in the cover portion of the vocal fold that cause deterioration of the vibratory properties of the vocal ... Read more...
A novel study of mechanical heart valve cavitation in a pressurized pulsatile duplicator.
30 Aug 2009 Submission of data regarding the cavitation potential of a mechanical heart valve is recommended by the U.S. Food and Drug Administration in the device-review process. An acoustic method has long been proposed for cavitation detection. However, the ... Read more...
