There is provided an ultrasonic diagnostic system in which an ultrasonic probe is detachably connected thereto, and ultrasonic waves are transmitted from the ultrasonic probe into the subject to obtain received signals through receiving the ultrasonic waves reflected within the subject, thereby displaying for a diagnosis an image carrying information based on the received signals, and is also provided an ultrasonic module including a processing circuit for the received signals, the ultrasonic module being used in the ultrasonic diagnostic system. The diagnotics system and the diagnostic module according to the present invention permit the more extensive patients to have an ultrasonic diagnosis, and also permit the operator to have a higher level of computer support. The ultrasonic module is connected through a general-purpose interface to a computer system. An ultrasonic module, which has, as a main element, an analog unit for performing an analog signal processing, is connected to another computer system.

Ultrasonic module and ultrasonic diagnostic system

There is provided an ultrasonic diagnostic apparatus in which ultrasonic waves are transmitted into the subject to obtain received signals through receiving the ultrasonic waves reflected within the subject, thereby displaying an image based on the received signals. In the ultrasonic diagnostic apparatus, a contact or non-contact of the tip portion of the ultrasonic probe with the subject is detected. At the time point when the non-contact is detected, a display mode of a CRT display is changed from a dynamic image mode to a still image mode (a freeze mode), so that a desired image is displayed in the form of a still image.

Ultrasonic diagnostic apparatus

An ultrasonic diagnosis device comprising a probe having an ultrasonic sensor rotatable about a central axis thereof. The sensor is adapted to carry out ultrasonic sector scanning. The device also includes a display for producing a sectional image of a portion of a patient. A bright line corresponding to the central axis of the sensor is produced together with the sectional image on the display. A first sectional image is produced on the display when the sensor is in a first rotational position. The bright line is then produced over the sectional image, and the position of the sensor is adjusted so that the bright line passes through the center of an object in the image. The sensor is then moved to a second rotational position, and a second sectional image is produced on the display.
