Recently, Fujifilm released the portable ultrasonic diagnostic device "FUJIFILM FC1", which was the first product jointly developed with SonoSite (now FUJIFILM SonoSite) acquired in April 2012. Equipped with a newly developed microprocessor (MPU) with strong image processing capabilities, high-resolution images with excellent rendering capabilities are available. Fujifilm said that the diagnostic device can be carried away with one hand, suitable for on-the-spot inspection and diagnosis (POCT: Point Of Care Testing). The new product will be available for sale starting May 12, 2014.
FUJIFILM FC1 released this time
FUJIFILM FC1 combines Fujifilm's image processing technology with FUJIFILM SonoSite's case miniaturization and probe stabilization technology. Its biggest feature is that it maximizes the image processing technology that Fujifilm is good at, and achieves the same high image quality as the desktop diagnostic instrument.
The new product uses two major image processing technologies. The first is equipped with a newly developed Many Core Processor, which greatly increases the computing power, so that the huge data obtained by the probe can be processed at high speed. It also prevents the phenomenon that the speed of sound caused by the measured hardness of the human tissue is unstable and the image is blurred. The working principle is that, with a high degree of computing power, the images measured at different speeds of sound are processed by software, and the speed of sound at which the highest resolution is obtained is selected, and the image is obtained by this factor. Previous products used a fixed speed of sound to acquire images regardless of the hardness of the tissue.
The multi-core processor equipped this time was jointly developed by Fujifilm and Japanese semiconductor manufacturers. Yamazaki said that the high-performance processor for ultrasound diagnostics, including the desktop diagnostics, is "the first in the industry."
Technical experience with X-ray machines The second image processing technique uses "multi-frequency processing" that emits ultrasonic waves of multiple frequencies to offset noise, reducing speckle noise. Speckle noise refers to a phenomenon in which scattered light generated by a scatterer having a wavelength smaller than that of ultrasonic waves interfere with each other to generate a speckled image. In general, if speckle noise is reduced, the image of the boundary portion of the tissue is also likely to be blurred. This time, this is avoided by edge enhancement processing. Yamazaki said that "the image processing experience we have accumulated on the X-ray machine" is used here.
With the above improvements, the new diagnostic instrument can obtain vivid images such as tiny liver tumors, and can clearly observe attachments (precipitates) such as the inner wall of the carotid artery. Precipitates are substances that are prone to cause cerebral infarction.
