An ultrasonic diagnostic apparatus is disclosed for imaging 3-dimensional images by irradiating ultrasonic waves to an object and reconstructing the 3-dimensional image. The ultrasonic diagnostic apparatus includes an ultrasonic probe for transmitting/receiving ultrasonic waves to/from an object to be examined, an ultrasonic image construction unit for constructing a 3-dimensional ultrasonic image based on the 3-dimensional ultrasonic image data from the ultrasonic signals received from the ultrasonic probe, and a display unit for displaying the 3-dimensional ultrasonic image. A position sensor is provided for detecting the position of the ultrasonic probe. A positional information analyzing unit stores the first position of the ultrasonic probe obtained from the position sensor and analyzes the positional relationship between the first position and the second position. The ultrasonic image construction unit converts the 3-dimensional ultrasonic image data obtained at the second position into a 3-dimensional ultrasonic image at the first position according to the positional relationship, thereby constructing the 3-dimensional ultrasonic image at the first position.

When a series of plural data processes are processed by different processors, the need to harmonize the processing cycles between the respective processors and adjust the processing time is obviated. The invention includes a data conversion section 20 that generates ultrasonic image data using RF data based on reflected echo signals received from a subject. The data conversion section 20 includes a plurality of processors 20a to 20h that perform a series of data processes related to an ultrasonic measurement mode and a buffer memory 20m that stores the processing results. The respective processors 20a to 20h perform processes that are assigned to them in accordance with a write request of their own processor, write the processing results in the buffer memory 20m, and read the processing results written in the buffer memory 20m in accordance with a read request of other processors.
