KJ-4001 Portable B ultrasound machine

Portable structure and it can be applied in the internal organs of the abdomen and in the gynecology and obstetrics diagnosis.

Functional characteristics:

The KJ-4001 B ultrasonic diagnostic instrument (hereinafter refers to as instrument) adopts 3.5MHz electronic convex array probes and introduces the image processing technologies such as the changeable frequency, 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 five 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.

The instrument has a large 256 images memory and may supply the diagnosis with real-time images and may check images one by one. It has the large capacity 128 image permanent storage. It may survey and calculate the distance, the area, the perimeter, the heart rate, and the pregnant week (five ways: BPD, GS, CRL, FL, and the AC) and so on; has the Chinese and English transformation;16 kind of false 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.
