TL;DR: The study demonstrates that optoacoustic imaging strategies can improve the identification of SLN metastasis as an alternative to current invasive SLN excision protocols and indicates that a noninvasive, nonradioactive MSOT-based approach can identify and determine SLN status and confidently rule out the presence of metastasis.

TL;DR: Clinical Doppler studies showed that the proposed echocardiographic method based on the continuity equation is fast, clinically-compliant and does not require complex training and will potentially enable investigators to study of additional quantitative aspects of intraventricular flow dynamics in the clinical setting by high-throughput processing conventional color-Doppler images.

High-contrast ultrafast imaging of the heart
TL;DR: Spatial coherent compounding provided a strong improvement of the imaging quality, even with a small number of transmitted diverging waves and a high frame rate, which allows imaging of the propagation of electromechanical and shear waves with good image quality.

Real-Time Two-Dimensional Blood Flow Imaging Using an Autocorrelation Technique
TL;DR: In this paper, a new blood row imaging system is described that com- bines a conventional pulsed Doppler device and a newly developed AU-to-correlator, in which the direction of blood Row and its variance are expressed by means of a difference in color and its hue, respectively.

Synthetic Aperture Radar
TL;DR: In this paper, a simple circuit-theory model is developed; the geometry of the system determines the nature of the prefilter and the receiver (or processor) is the postfilter.
Real-Time Two-Dimensional Blood Flow Imaging Using an Autocorrelation Technique
TL;DR: In the system blood flow within a given cross section of a live organ is displayed in real time and the direction of blood Row and its variance are expressed by means of a difference in color and its hue, respectively.
