Abstract: In a method of displaying a biplane image in real time in an ultrasonic diagnosing apparatus, ultrasonic waves are transmitted from a biplane probe to a portion of a sample to be diagnosed to scan two sectional planes that intersect orthogonally at an axis of intersection. Echo signals reflected from the sample portion are received by the probe. A tomographic image of each of the two orthogonal sectional planes is displayed on a display unit, each of the two displayed tomographic images being divided into two tomographic image planes along a line of intersection representing the axis of intersection of the two sectional planes. An image for inputting a visual field direction is also displayed on the display unit. Using an input device, a parameter indicating a chosen visual field direction is input to the image for inputting the visual field direction. Affine transformation parameters of the two displayed tomographic images are operated using the parameter of the chosen visual field direction.
