The approaches to operative spatial visualizations of internal structures of heart

Abstract

Expression of the internal structures of the body of a person may be obtained by means of X-ray devices. The method has so far had no alternatives in surgical practice in terms of being efficient, of width of envelopment of the operating field, of validity and for displaying the objects in real-time. X-ray techniques however have an inherent number of defects: in the image of the investigated object information from accompanying body tissues interferes; the X-ray image in principle does not obtain information on the depth of the displayed structures (it's flat).
