Pulse subtraction Doppler

Pulse subtraction Doppler

Recent advances have demonstrated the feasibility of molecular imaging using targeted microbubbles and ultrasound. One technical challenge is to selectively detect attached bubbles from those freely flowing bubbles and surrounding tissue. Pulse Inversion Doppler is an imaging technique enabling the selective detection of both static and moving ultrasound contrast agents: linear scatterers gener...

Pulse-Doppler Ultrasound and Its Clinical Application

Doppler devices can provide clinically useful information about blood flow. This paper describes how a pulse-Doppler instrument has been linked to a B-scan machine so that flow patterns in any ultrasonically accessible vessel can be monitored from the skin surface. The same transducer is used for both modes of investigation to enable accurate and reliable positioning of the sample-volume. After...

Clutter Detection in Pulse-doppler Radar Systems

CLUTTER DETECTION IN PULSE-DOPPLER RADAR SYSTEMS Ahmet Güngör M.S. in Electrical and Electronics Engineering Supervisor: Assist. Prof. Dr. Sinan Gezici August 2010 Among various types of radar systems, the pulse-Doppler radar is the most widely used one, especially in military applications. Pulse Doppler radars have a primary objective to detect and estimate the range and the radial velocity of...
