The Real-time Virtual Sonography (RVS) is a system to depict a CT/MR/US reconstructed image of the same slice as that of the ultrasound image in real time from a CT/MR/US volume data.
First of all, carry out positioning to agree the position of the ultrasound probe with the coordinate system of CT/MR/US data.
A method is prepared to start synchronization of the CT/MR/US image and real-time US image from the point where an ultrasound image agreed with one of CT/MR/US images is obtained, thus positioning can be performed smoothly.
According to movement of the probe, the ultrasound image and CT/MR/US image vary in real time. Both images of the same slice can be observed while comparing them displayed side by side. Also it has a function to save the observation screen of RVS as digital stationary image or cine image.
