2.6 System Principle

The fundamental operating principle of diagnostic ultrasound system is: through the transducer, electric excitation signals are converted into acoustic signals, which are propogated, attenuated and reflected in the patient’s body. Then the echos from the body are converted into electric signals through the transducer. Going through complicated signal processing circuit, a scanned tomographic image is displayed on the monitor.

The block diagram of the system is displayed below:

Fig.2-6a Block Diagram

Page 21

4701-0040-01A

2-9

According to the design, the Digital Beam Former sends out transmit pulse signals at a certain frequency. Going through signal driving and logic switch, the signals are sent to the elements of the transducer. With the oscillation of element, ultrasonic waves are generated. The combinations of many element signals enable the transducer to send out a dynamic directional compounded beam. Then the beam is propogated and attenuated in the human body. When the echo returned to the element crystal, it will be changed to electric signals again. Being amplified by the pre-amplifier, the signals are sent for A/D conversion, through which analog signals are converted to digital signals, compounded in the beam former, go through digital signal processing such as filtering, logarithm compression, detection and form digital beam data stream. The beam data steam is sent to the CPU board goes through scan transform and video processing. Finally, an ultrasonic image is displayed on the monitor.

The core of the CPU board is a built-in Linux system. In addition to completing display of ultrasonic images, it accepts keyboard operation commands from the user, and changes them to internal executable commands. Moreover, it will achieve all kinds of measurement and calculation, data input and output of peripheral ports, and so on. The system can also work with peripheral devices such as a printer, a network device or an external memory, so as to extend system functions.

Fig. 3.6.2.2.9 Fetal Growth Curve (one graph/ four graphs)

3.6.2.2.11 Fetal Biophysical Profile (FBP)

When conducting FBP, acquire indices of fetal growth through testing or measurement, and use the grading method to evaluate if the fetus is at risk, which serves as a guiding index in clinical processing.

Page 79

The FBP testing and measurement shall cover the following 6

indices:

Fetal Heart Rate (FHR)

Fetal Motion (FM)

Fetal Breathing Motion (FBM)

Fetal Tension of muscle (FT)

Amniotic Fluid (AF)

Placenta grading (PL)

Where in AF is acquired by measuring amniotic fluid depth; PL is based on placenta ultrasonic image, for which the placenta maturity is divided into 3 levels: Level 0,1,2.,3.

While the other indices are obtained through fetal reaction test, the fetal reaction test takes about 20-30 minutes.

Grading standard:

1) Fetal Heart Rate (FHR)

Observation duration: 20 minutes

Grading standard:

2: When fetal moves, FHR accelerates>=15 times/min,

duration>=15S, >=5 times;

1: When fetal moves, FHR accelerates >=15 times/min, duration

>=15S, 1～4 times;

0: When fetal moves, FHR accelerates <=1 time.

2) Fetal Motion (FM)

Observation duration: 30 minutes

Grading standard:

2: FM>=3 times

1: FM 1～2 times

0: No fetal movement

3) Fetal Breathing Motion (FBM)

Observation duration: 30 minutes

Grading standard:

2: FBM>=1 time, duration >=60S

1: FBM>=1 time, duration 30～60S

0: No FBM, or duration <=30S

4) Fetal Tension of muscle (FT)

Observation duration: 30 minutes

Grading standard:

2: >=1 time, extension and bending of extremities and the spine

1: >=1 time, extension and bending of extremities or the spine

0: extension of extremities, no bending, with hands open

5) Amniotic Fluid (AF)

Grading standard:

2: AF max. Depth>2cm

1: AF max. depth1～2cm

0: AF max. Depth<1 cm

6) Placenta grading (FL)

Grading standard:

2: PL<=2

1: back wall placenta, difficult to determine the PL

0: PL=3

Based on single indices the fetal growth status is acquired as below:

2: Normal

1: Slightly abnormal

0: Obviously abnormal
