Enhancement of stents using interference of low-frequency ultrasonic echo signals.

Purpose: We set out to enhance the imaging of stents used for coronary coarctation surgery without imaging the reticulation of the stent. Because the stent is a reticulated structure, there is a relation between ultrasound wavelength and the interstice reticulation that produces the echo.

Methods: First we performed computer simulation by ultrasound frequency of transmitted signals to analyze this relation.
