生体内設置用標準反射体及びそれの使用り法に関する。Detailed Description of the Invention (Field of Industrial Application) The present invention relates to an auxiliary means for medical ultrasonic diagnostic drawing, and more specifically, to an auxiliary means for medical ultrasonic diagnostic imaging, and more specifically, when an ultra-high wave diagnostic device is used to view in-vivo images. The present invention relates to a standard reflector for in-vivo installation suitable for quantitatively measuring the reflection characteristics and speed of sound around it by observing its reflected waves, and its usage.

等々の特性を右していることによる。(Prior Art) Ultrasonic diagnostic method is well known as a method for non-invasively examining the properties of living tissue. The feature of this method is that ultrasound is irradiated to the area, and diagnosis is made by examining the ultrasound absorption (attenuation) and its frequency dependence of the region of interest from the T]-signal (especially from the T-signal only). Information is available on 116 Sada. this is,
This is due to the fact that ultrasonic waves have excellent properties as carriers of signals and information. In other words, ultrasonic waves are self-propagating, have little waveform distortion during propagation, have a wide dynamic range, and can be effectively converted into electrical signals and vice versa. .

苦う理由に帰着する。(Problem to be solved by the invention) However, since the above characteristics are not ideally exhibited in actual ultrahigh wave diagnostic equipment, it is difficult to say that ultrasonic diagnostic method is a universal diagnostic method for medical use. (To put it in an extreme way, ultrasound diagnostic methods are not in a situation where they can be trusted enough in clinical practice.) This is a bit of a guess, and it's a shame. I can say that. In other words, this difficulty comes down to the fact that there is no reflection source in the living body that can serve as a reference for reflexivity.

The objective is to provide the body and its use.

Good too. For example, it may be possible to perform the procedure visually by making a small incision laparoscopically. In this case, rather than embedding the standard reflector in the organ, it may be inserted between the organs and fixed and covered with a retaining means, such as a thread made of a non-absorbable material.
