    Abstract: PROBLEM TO BE SOLVED: To quickly and comprehensively acquire M-mode information by using the two-dimensional display within the three-dimensional display for space, and using the third dimensional display for time. SOLUTION: A B-mode signal is converted into an image, and a three- dimensional image 40n is formed by a 3-D drawing processor. The image 40n is acquired in the order of 401 , 402 .... Multiple images 40n are acquired at the frame speed of multiple frames/sec. The time frame-frame interval is obtained as Δ=1/Frate . A three dimensional image is formed, where the (x), (y) in the image set indicate the (x), (y) values on a specific image frame and (z) indicates the time position of the frame (n) in the time series of flames. This three dimensional image is rotated on both (x), (y) axes, and a bulkhead and a rear wall are displayed in the three-dimensional display: two-dimensional display for space and one-dimensional display for time. Comprehensive information can be quickly obtained.
