Medical electronic technology status and trend analysis

A resolution of 16-bit, sampling rate for ADC, 170MSPS pixels to 2560 * 2048, gray-scale display as 1786-LCD ....

These sophisticated electronic technologies are being developed for the latest medical equipment.

Japan THine electronics company is developing the highest sample rate up to 170MSPS, resolution, 10-bit ADC.

The company plans to begin early in 2005-2006 to the needs of medical device products.

Japan International display technology (IDTech) company is developing for the medical device's LCD screen.

Ke-MG company in February 2005, the market for breast cancer diagnosis breast x-ray photography equipment (breast image recording devices).

In that subsection equipment used in the application phase contrast technology, camera system allows photography image picture quality has been greatly improved.

Image diagnostic equipment, basic performance improvement are concentrated in improving diagnostic accuracy.

It is a very high accuracy for more information (sensors), and those information lossless, high speed land transforms into a digital signal transmission (ADC, signal transmission), and then to the signal as a basis for drawing up the required diagnostic images (image reconstruction), and then correctly displayed (display device).

With State-of-the-art electronic technology development trend of the corresponding image diagnosis equipment to make rapid progress in x-ray CT equipment in the area of multiple columns.

The so-called multiple-column, is in the device-side set multiple column x-ray detector, one can shoot multiple images, thereby expanding the scope of the examination and the shortening of the time.

Medical equipment of Moore's law: after 1990, x-ray detector columns to approximately every 1.5 years doubled speed increase, now up to 64 columns of products have been put to use to configure 128 columns detector products already under development.

While the medical equipment of renewal period is approximately 10 years.

In Japan's new energy/industrial technology development organization (NEDO) and the Institute of radiation medicine comprehensive support of Toshiba medical systems Corporation has developed for x-ray CT device 256 columns detector.

To improve the performance of the x-ray device, and not only the number of columns in this direction, you can increase the resolution.

Siemens Medical Solutions does not pursue multiple columns and steering increase resolution. The key to improving the resolution is to make x-ray focus position in 1 seconds and back shimmy 2320 times, this is a kind of x-ray tube, electron beam control technology.

The latest electronic technology objectives

In order to meet the medical equipment of the "clear" and "small and low demand for various kinds of" electronic technology will be applied to the latest medical device development.

Among them, facing the "clarity" is display, ADC, signal transmission and SiP devices, and other technologies, but small and low-oriented "," the motor control, cameras, etc.

1. clearer display of sick site

"Clarity" mainly diagnostic equipment needs.

Aimed at a more realistic display of diseased parts of the image to improve diagnostic accuracy, reduce the possibility of misdiagnosis, and early detection of diseases, etc. Display the number of pixels has reached 5 million aunts, gray-scale display to 1786, can more accurately display the image. 16-bit ADC in high resolution at the same time achieving a low-power, when designing large-scale use of ADC's latest image diagnostic equipment, help to solve the problem of heating equipment. In order to obtain high resolution images, such as medical devices within the auditions, attempting to increase the pixel CCD camera, is advancing digital interface application signal transmission technology can support.

Boost subdivide grayscale contrast completely

International display technology (IDTech) companies in the medical equipment in the field of LCD control the market share of first place.

Medical devices with LCD screen, you must have one of the conditions is to compare the reading is very high, not easy to capture can express. To do this, you typically remove filter (causing the main factors reducing the contrast), converted to black and white display. Filter color will make the external light scattering, lead to contrast formation. Remove filter in addition to improve contrast ratio, but also to increase the brightness. In this way, a filter is not clear spots, have become clearly visible. Such spots easily misdiagnosed, in order to reduce the display dot, you also need to adopt more advanced manufacturing process to control the LCD display interval (holding the two pieces of liquid crystal glass substrate between) of discrete.

2. reduce the damage to the patient

"Small and low in addition to urging the zoom out" the volume of the device, also called for no damage (low damage) patients medical health.
