Color strikes, how should we respond? (1)

"In the United States, vascular disease is the cause of death and disability," ADI Asia Pacific medical Enterprise senior business manager Zhou Wen sheng tell EEWORLD.

This is not an alarmist, especially in emergency situations, accurate use ultrasound to determine the location of the trauma related to the survival of life.

However, unlike other than medical electronic equipment and ultrasound diagnosis is not a recent rise of the concept.

As early as the 1960s, industrial inspection ultrasound instruments has already begun to study human ultrasonography, thus, the development of China's ultrasound has undergone by A hyperlink to the M-, b-to-color, full-upgrade process. In the late 1980s, color start going into our vision.

20 years have passed, covers ultrasonography equipment market 15% of shipments in diagnostic it seems their age and not "disproportionate", but its sales volume but representing more than 70% of a population.

Where multinational corporations in occupies an absolute advantage Doppler ultrasound markets, nearly 90% market share. More local enterprises to enter the market of color, especially high-end market, have a long way to go.

High-performance PK "can be equipped with Pocket"

It cannot be denied that in some perspective, Chinese manufacturers are started from the low-end products.

But for ultrasonic equipment and patient monitors, and other applications, the Chinese manufacturer already has a very high technical level, and are both domestic and international market share. At the same time, more and more applications market is developed: portability promote ultrasonic system to smaller size evolution to meet the user to install the "Pocket" complex ultrasonic tool needs, particularly in the power system is not stable or is not reliable local, as remote village clinics, emergency medical services, animal farm, bridge, and large machinery and equipment repair workshop, portable devices have unique conditions. At the same time, the high performance requirements makes ultrasonic equipment need to include the maximum number of channels, features, and options, allowing doctors to better diagnosis, resulting in System Designer and system components make increasingly higher demands. "Compared with portable power here is not a key drivers," said Paul is better. Because these systems are often used in the patient's bedside, theatre, or nurse triage units, but performance is critical, because these systems are used for diagnosis of human diseases.

However, according to Paul sheng, real independent research and development of local manufacturers and color.

It is precisely in order to help such enterprise fast growth, reduce the complexity of the system design, designed for mid-range and high-end push ultrasound system AD9276 and eight-channel ultrasonic receiver AD9277 was born. The series of chips in a single chip integrates CW Doppler signal processing gain, filtering, data conversion and demodulation functionality.

"CW Doppler is different from other medical ultrasound technology," ADI healthcare sector director Patrick O ' Doherty said, "the CW Doppler measured Doppler (detection of the ultrasonic signal frequency and phase change) to determine the blood vessels, veins, and arteries in the flow direction and speed.
