In digital hospitals, digital medical records will enable doctors to access patient information from anywhere, and healthcare providers don't have to wait a few days to get X-rays from the lab because the images of digital X-ray machines can be instantly captured and Analyze. To this end, all diagnostic devices are networked through the network, and all patient information (CT slices, X-rays, etc.) can be transmitted to the data storage server for immediate access. This trend will drive medical electronics suppliers to develop interoperable imaging devices with a consistent user interface. In fact, each vendor is not only providing diagnostic equipment, but also providing data storage servers and service software.
These new trends will lead the development of the medical electronics industry, which means that better and faster diagnostic equipment can be used to connect patients to the healthcare system for early disease diagnosis and treatment. This is the vision of the development of medical electronics and the reasons for its enormous growth potential.
At the 2008 China International Medical Equipment Fair, medical electronic devices are mainly divided into testing, diagnosis, treatment, monitoring and preventive health care. The market presents ultrasound/imaging equipment, personal medical equipment, and automatic external defibrillation equipment. The bio-medical electronic devices, medical and health electronic devices, etc., the three-dimensional and four-dimensional display and its equipment have become the highlights of the Expo with colorful colors. Various types of endoscopes are realized by photoelectric detection technology. People lament the magic of the micro world.
After watching the dazzling new products, people want to know which semiconductor technologies support the technology and market development of medical electronic devices. This is also the focus of readers of the 2008 China International Medical Electronics Technology Conference.
Medical imaging drives continued demand for high-performance signal processing devices and technologies
High-end imaging and monitoring technology makes accurate, fast, and real-time diagnostics possible, reducing the number of surgeries caused by unnecessary surgery or misdiagnosis, and supporting preventive treatment. For example, real-time X-ray imaging gives doctors a greater chance of choosing alternative treatments than surgery. As the computational performance requirements for medical imaging devices continue to increase, the demand for high-end signal processors (DSPs) and field-programmable gate arrays (FPGAs) is increasing. On the other hand, according to Frost & Sullivan's latest forecast, the demand for FPGA, DSP and ASIC in the global medical imaging equipment market will increase from 602.87 million US dollars in 2006 to 917.15 million US dollars in 2011.
Medical imaging equipment addresses a variety of requirements for processing, including data acquisition, high-performance computing, image processing algorithms, mathematics, and high-capacity, efficient storage media and high-bandwidth medical IT infrastructure required to access memory data. and many more. In the field of data transmission, fiber transmission and Gigabit Ethernet wireless link transmission will be a promising solution because the data processed by the imaging device is not a continuous real-time data stream, but a large data block required to form an image. On the other hand, with the development of high-definition medical display devices and technologies, especially the development of medical 3D and 4D display technologies, a series of bandwidth indicators for image processing devices, transmission media, storage and devices will be raised. The requirements, therefore, will be one of the commanding heights of future competition. Among them, the competition of multi-core processors, FPGAs and DSPs is undoubtedly a highlight worthy of continued attention. In addition, with the development of portable ultrasound/imaging devices, there will be a huge demand for optoelectronic sensors, ultra-low power multi-channel A/D converters, processors, algorithms, and analog front end (AFE) devices that increase display resolution.

Strict safety regulations require the emergence of an emerging medical power industry
At present, the electronic safety test related to medical electronic equipment recognized in the world is IEC 60601-1, and IEC 60601-1 covers all general provisions, including the hazard list and risk tolerance. Among them, the IEC 60601-1-X parallel standard series specifies that the main targets are electrical medical equipment systems, electromagnetic compatibility, X-ray protection, etc., and must be applied simultaneously with IEC 60601-1; IEC 60601-2-XX series regulations apply to specific Medical equipment must be applicable to both IEC 60601-1 and IEC 60601-1-X.
In medical electronics, electromagnetic radiation and electromagnetic radiation protection are key factors influencing the design of power systems. For example, qualified medical power supplies should comply with EN60601-1-2; this standard must be compatible with many technical requirements related to EMC, especially medical power supplies must meet IEC61000-4-2 ((electrostatic protection capability, required to reach 3kV), IEC61000- 4-3 (RF radiation protection capability, required to reach 3V/m), IEC61000-4-4 EFT (voltage transient withstand capability, required to reach 1kV), IEC61000-4- 5 (mains surge current capability, required to reach 1kV and 2kV), IEC61000-3-2 (mains line harmonic requirements), IEC61000-3-3 (power line flicker requirements), and EN55011 (Class A product or B product radiation limit).
According to experts at the Medical Expo, the EMC standard for medical devices issued by China YY0505-2005 "Medical Electrical Equipment Part 1-2: General Requirements for Safety - Parallel Standards:
The Electromagnetic Compatibility - Requirements and Test Methods will soon be enforced. Medical electronic equipment includes life support equipment and non-living support equipment. Therefore, medical power system design engineers only need to fully understand the above-mentioned relevant regulations and regulations, and it is possible to design a power supply system that meets the requirements of patient safety. The biggest difference between medical power design and commercial power supply design and the biggest challenge.
Due to the high standard requirements for medical power system design, the use of dedicated power supplies that meet medical safety specifications is one of the important development trends in the market. At present, a group of power supply manufacturers for medical electronic devices has been formed. For example, Electric Shengda Co., Ltd. has launched the SWS1000L in the SWS series power supply line with medical safety specifications, with 5V, 12V, 24V three output voltage options, of which SWS1000L-24V peak power can reach 1224W. SynQor introduces the ultra-small 400W medical power module, which delivers 400W of useful power in a 3" x 5" x 1.44" finite size, which is considered to be the smallest of the world's equivalent power output modules.
Telemedicine will be the future trend
In addition to the above, with the development of broadband mobile wireless communications and ultra-low power radio technologies, and the application of micro-sensors, implantable ICs and RF transceiver chip technologies in healthcare, future telemedicine will Making healthcare ubiquitous will drive the development of RFID, networked robots, sensor networks, broadband mobile communication systems, software radios, MIMO technology, etc., and further drive RF ultra-low power amplifiers and LNAs, software configurable RF The development of devices, antennas, implantable chips and sensory robots, in addition, the application of these new devices will drive the development of new packaging technologies. Therefore, it can be predicted that in order to accelerate the improvement of the health level of human society, the development of medical electronic technology will inject unlimited business opportunities into the semiconductor industry.
