Endocavitary Contrast-Enhanced Ultrasound
RöFo - Fortschritte auf dem Gebiet der Röntgenstrahlen und der bildgebenden Verfahren, 2022Background Ultrasound is one of the most important imaging methods in the daily routine. Contrast-enhanced ultrasound (CEUS) has put ultrasound on equal footing with computed tomography and magnetic resonance imaging in many areas. Although ultrasound contrast agents are commonly administered intravenously, endocavitary application as ...

Contrast enhancement for the myocardium
Magnetic Resonance in Medicine, 1991AbstractThe potential of MR imaging and spectroscopy in ischemic heart disease is substantial. MR contrast media have the potential to improve the differential tissue characterization among normal, ischemic, and infarcted myocardium. Several reports in animals and patients have revealed that MR contrast media can improve the delineation of acute ...

Contrast enhancement for backpropagation
IEEE Transactions on Neural Networks, 1996This paper analyzes the effect of data-contrast to a backpropagation (BP) network and introduces a data preprocessing algorithm that can improve the efficiency of the standard BP learning. The basic idea is to transform input data to a range that associates the high-slope region of the sigmoid function where a relatively large modification of weights ...

A technique for the contrast enhancement of a picture is proposed. The method is derived from the entropy concept of information theory. The originality of the algorithm rests on the use of a local contrast to define the digital entropy. The basic idea of the treatment is to enhance the contrast by transforming the global entropy.

Contrast-enhanced ultrasound imaging is a recently approved technique in the United States that uses a specific contrast agent, namely, microbubbles, consisting mainly of a gas core and a stabilized biological shell. These compounds allow for the visualization of small vascular beds and improve characterization of anatomic structures and lesions.

Contrast-Enhanced Ultrasonography
2012Ultrasound is the cornerstone for prostatic imaging and covers diagnostics, therapy monitoring, and follow-up. In the aspect of focal therapy, accurate prostate cancer localization is mandatory. Contrast-enhanced ultrasound (CEUS) is a promising imaging technique which has shown to greatly increase the chances to find prostate cancer in biopsies.
