Give some suggestions of a developer's of medical treatment electronic equipment
The medical treatment electronic equipment is becoming more and more complicated, the engineer faces the increasingly many challenge while developing these apparatuses too, how to meet the challenge of these? April 21, sponsored by intention era, under 2008 international medical electron technology conferences of China which the electronic branch of biomedicine of Chinese institute of electronics does jointly (abbreviate as CMET2008) Hold ceremoniously. First as China to pay close attention to the professional technicality forums of electronic technological scheme of medical treatment and development, this conference has attracted including stepping Ditter magnetic resonance Co., Ltd. Actel in Siemens, TI, NI, Xilinx, ADI, Altera international medical electronic devices and components inclusive supply the giant and participate the meeting. The expert participating in the conference designs making an excellent speech on the medical electron in the native country, and put forward some good suggestions on the electronic designer of native medical treatment.
Siemens step the intersection of Ditter and the intersection of magnetic resonance and Co., Ltd. research and develop the intersection of executive vice president and Ni Cheng Dr. combine Siemens develop large-scale experience of medical equipment to develop full-length diagnostic facility research and develop person Propose the following suggestion:
1,Get involved in the development of the magnetic resonance system in early days, and will certainly should notice the apparatus can’t contain the magnetic medium, otherwise will result in developing the working trouble of the apparatus;
2,Can choose CAN or EPL such maturity bus line technology on the system bus;
3,Even if the apparatus developed by oneself already through standards such as EMI,etc., but can guarantee this apparatus either and the magnetic resonance apparatus is compatible, so must carry on rigorous security testing;
4,Native the intersection of medical treatment and electronic manufacturer have only less the intersection of research and development and personnel often, this up to a hundred people’s development group have no advantage to compare easily with foreign the intersection of medical treatment and electronic manufacturer, so the native developer should aim at and can lower costs and can produce the apparatus development of benefit first.
5,Consider the integration of medical information in the future.
Actel advanced to employ engineer and concurrently Dai MengLin, technological manager of the Asian-Pacific area, think the medical electron concerns people’s life live in Company, so must possess the high reliability, because the seed penetrating power in the cosmic ray is extremely strong, will influence the molecule state in the silicon component at present, so the electronic developer of medical treatment should pay attention to the radioprotective ability of the device while choosing the semiconductor device, moreover, it can be more serious that this kind of influence will dwindle with the size of semiconductor technology, so must cause and pay close attention to, he puts emphasis on considering the low power consumption demand for the walkie medical equipment at the same time.

Show that develops coloredly from the unicolor with the ultrasonic apparatus in Xilinx the Asian-Pacific area DSP products and solution marketing business higher level manager Lin HongRui, develop towards 3D, 4D from 2D picture, the number of channels of the ultrasonic apparatus will increase greatly, need high-performance beam to formate the framework in this way, and as the hospital promotes ultrasonic apparatus picture resolving ability and time demand for resolving ability, the required calculation sum of the apparatus will increase greatly, at this moment, the developer should consider adopting the advantageous FPGA device in DSP runs side by side and is handledding more, can achieve the goal that not only can also accelerate being developed to reduce the system cost.
Fig. 4: A typical ultrasonic apparatus system block diagramADI medical instrument products manager Paul Errico combines the experience of obtaining employment for more than 20 years by oneself to point out the development of the medical treatment electronic equipment is the most challenging, because the precision that it picks up, deals with, outputs to the signal is expected very much, and the life cycle of the medical treatment electronic equipment is very long, all have more than 25 years at least, so the apparatus quality developed should be very high. He has developed and proposed the following suggestion on the medical electron:
1,The medical image apparatus in the future needs high-quality picture, meanwhile, want the frame per second to promote too, so should choose the high-performance device;
2,The ultrasonic apparatus future development trend is low power consumption, high performance and miniaturization, so should consider the integrated level of the device;
3,To reach the highest sharp image, one should pay attention to the choosing of the analog front end device of the apparatus;

Stanford University researchers have created a wireless way to charge your electric vehicles as you drive so EVs will never run out of juice halfway through a road trip.
Following Stanford University’s recent testing on Honda’s Fit electric vehicles, researchers at the university are now developing a new wireless system that will magnetically charge your EVs while you are driving.
The idea came after researchers recognized the disadvantages of electric vehicles’ limited driving ranges which may use less energy but run at a weaker strength. For example, the Nissan Leaf is only capable of driving less than 100 miles on a single full charge. To fully recharge the Leaf’s battery, users will have to wait approximately 10 hours and cannot bet on charging stations to be around on long trips. These drawbacks with EVs have not been addressed to date, discouraging the general market from making the move from traditional cars.
To combat this problem, Stanford researchers have created a “charge-as-you-drive” network which utilizes copper coils that will be embedded in highway roads and under the belly of the EVs. The coils will be tuned to the same natural frequency and as the car moves, a process called “magnetic resonance coupling” occurs, meaning when the road coils that are connected to an electric current power up, they send electricity to the receiving coil in the car and thus charging the EV’s battery.
EFRC Special Seminar with Vikram - Tuesday, February 12 at 11 am

Title: “Extending the Limits of Sensitivity and Resolution in NMR and MRI”
Speaker: Vikram Bajaj, University of California, Berkeley & Lawrence Berkeley National Laboratory
When: Tuesday, February 12, 2013 - 11am
Where: Interschool Lab 750 CEPSR
Abstract: Magnetic resonance techniques peer into materials and objects in their unaltered native states and elucidate the structure, chemistry, and dynamics within. This motivates many applications of NMR and MRI in the laboratory, the clinic, and in industry alike. Nevertheless, several possible applications of NMR are limited by its low sensitivity, due to the weak equilibrium polarization of nuclear Zeeman states on which the signal intensity depends.
Would anyone care to tell me what the fuck “nyquist ghosting” is, in relation to Echo Planar Imaging in MRI? (might be specifically to do with using TMS and MRI together, I can’t work it out)
Come on Tumblr. There must be a geek out there somewhere who can give me a hand.
Drop me a message I’ll love you forever.
