چکیده انگلیسی
To overcome frame rate limitations in high-frequency ultrasound microimaging, new data acquisition techniques have been implemented for 2-D (B-scan) and color flow visualization. These techniques, referred to as retrospective B-scan imaging (RBI) and retrospective color flow imaging (RCFI) are based on the use of the electrocardiogram (ECG) to trigger signal acquisitions. B-scan and color flow images are reconstructed by retrospectively assembling the processed data on a line-by-line basis. Retrospective techniques are used to produce the first in vivo B-scan and color flow images of mouse carotid arteries at frame rates up to 10,000 fps. Retrospective B-scan images of mouse heart were also produced at frame rates of 1000 fps using a version of RBI implemented on a commercial imaging system (Vevo660, VisualSonics, Toronto, ON, Canada). This technology enables detailed in vivo biomechanical studies of dynamic tissues such as the myocardium of the mouse heart with high temporal resolution. (E-mail: emmanuel.cherin@swri.ca)
