により医師が発育度を判定するようにしていた。 Generally, it is thought that the degree of fetal growth, that is, the weight and the number of days of fetal growth (gestation days) corresponds to the fetal head diameter. Therefore, conventional ultrasound diagnostic equipment is used to display an ultrasound image of the fetus, and from this image the fetal head diameter is measured using a ruler, etc., and a table prepared in advance showing the relationship between the fetal head diameter and the degree of growth is used. Doctors were to assess the level of growth.

示される。 An embodiment of the present invention will be described below with reference to the drawings. In the figure, a probe 2, an ultrasound transmitting/receiving device 3, and a display device 4 constitute an ultrasound diagnostic device. The probe 2 emits ultrasonic waves into the human body based on signals emitted from the transmitting/receiving device 3, and captures the echoes and converts them into electrical signals. This electrical signal is sent to the transmitting/receiving device 3, and further to the display device 4.
The display surface 41 is sent to
Above, it is displayed as a bright spot on the line corresponding to the ultrasound trajectory.

る。 According to the present invention, position signal generation circuits 51 and 52 are provided, and the position signals X 1 and 52 are DC voltages.
Y 1 , X 2 , Y 2 are sent to the display device 4 and point A (X 1 ,
Y 1 ) and point B (X 2 , Y 2 ) are displayed on the display surface 41 with a specific symbol such as a "+" mark.

部に表示される。 By adjusting the variable resistors 53 to 56 of the position signal generation circuits 51 and 52, the doctor can
, and set the distance between points A and B to the most suitable position representing the head diameter. This position signal is also sent to the multiplexer 6, and is sequentially selected under the control of the control circuit 11 and sent to the AD conversion circuit 7, where it is converted into a digital signal. Each position signal converted into a digital signal in this way is processed by an arithmetic circuit 8.
√( 1 − 2 ) 2 +( 1 − 2 ) 2 is calculated under the control of the control circuit 11, and the distance between points A and B is determined. In the read-only memory (ROM) 9, fetal growth information such as weight and number of days of fetal growth is written in advance at addresses corresponding to each head diameter. By reading out the address specified by the head diameter determined by the arithmetic circuit 8, the corresponding growth information is read out. The growth information thus read out passes through the character generator 10 and is turned into a signal of letters, numbers, or symbols, which is sent to the display device 4 and displayed on the display screen 41 together with the ultrasonic tomographic image 42 of the fetus. It is displayed in the form of a symbol, for example, at the bottom of the ultrasound tomographic image 42.

の向上に役立つ。 Therefore, according to the present invention, by simply operating the variable resistor and setting two points, the doctor can automatically obtain fetal growth information from the display screen on which the ultrasound image of the fetus is projected. This helps improve diagnostic efficiency.
