1 May 19903-D display of ultrasound B-mode image by holographic stereogram
The plane type white light reconstructed holographic stereograi ( PWHS ) is made from the element holograms using the photograph of many different viewpoints. It is useful when we take hologram of object which can not taken hologram directly. On the other hand we want to see the inside of human body visually in the 3-D image. For these reasons we apply the technique of holographics tereogram( US ) to the ultrasound B-mode images and display 3-D image directly. Moreover we consider the distortion of the reconstructed image and consider (4)-('l') the method of distortion correction. Finally we want to apply this system to the medical fetus diagonosis.
