This Ultrasonic diagnostic instrument (here in after refers to as instrument) adopts 3.5MHz electronic convex array probes and introduces the image processing technologies such as the changeable aperture, dynamic changes of marks, the multistage electronic focus, the dynamic filter, the logarithm compression, the image enhancement, the line correlation, the frame correlation, and the linear interpolation, etc.
The instrument has such four display modes as B, B/B, 4B, B+M, and M. Under the B mode there are six magnifications: ×0.8, ×1.0, ×1.2, ×1.5, ×1.8 and × 2.0. It can be applied in the internal organs of the abdomen and in the gynecology and obstetrics diagnosis. The B+M and the M modes may be used in the routine examination of the heart.
The instrument has a large 256 images memory and may supply the diagnosis with real-time images and may check images one by one, also with the large capacity 128 images permanent storage. It may measure and calculate the distance, the area, the perimeter, the heart rate, and the pregnant week (eight ways: BPD, GS, CRL, FL, HL、OFD、TTD、and the AC) and so on; has the Chinese and English transformation; 16 kinds of color processing; it also has the function of noting such as noting the real-time clock, the serial number of the medical record, many kinds of body marks and the full-screen character.
The electric circuit adopts large scale integrated circuit FPGA, the mass memory and the surface mounting technology (SMT) and so on; and the product performance is reliable.
