The frequencies used for medical imaging are usually within the vary of 1 to 18 MHz. Higher frequencies have a correspondingly smaller wavelength, and can be utilized to make sonograms with smaller particulars. However, the attenuation of the sound wave is elevated at larger frequencies, so in order to have better penetration of deeper tissues, a decrease frequency (three–5 MHz) is used. Images from the ultrasound scanner are transferred and displayed utilizing the DICOM normal. Normally, little or no publish processing is utilized to ultrasound photographs.
The FDA requires that the machine not exceed established limits, which are fairly conservative in order to take care of diagnostic ultrasound as a protected imaging modality. This requires self-regulation on the part of the producer when it comes to the machine’s calibration. It renders “live” images, the place the operator can dynamically choose the most useful part for diagnosing and documenting adjustments, usually … Read More
