The visualization with ultrasonic waves is one of the most widely used in medicine methods. Currently in medicine mainly is spread echographyc ultrasound method, less exposure to radiation. These methods are acceptable in defectoscopy, as there is important to the discovery of the defect. In contrast to the defectoscopy, in medicine aims to not only detect the object and visualize organs and different formations in them. Satisfy these requirements may acoustic holography. This article is devoted to acoustic holography, which, as well as optical holography provides a three-dimensional image of the object. Is considered the method of the surface relief, based on the ability of the fluid to deform under pressure in the acoustic wave. The basic theoretical standings necessary for calculation of devices, grounded on this method are analyzed. We derive the expressions needed to calculate the geometric position of the image, as well as its size. Based on these results it is concluded that there will now optoelectronic matrix with a pixel size of the order of nanometers make a very promising imaging of small size, derived from acoustic holography. In addition, these |
