Hydraulic induced volume densimeter and testing method, use thereof

Abstract

The volume density meter consists of a number of trays set on case and relevant measurers as well as electronic components set in case. The electronic circuit formed by the electronic components is connected to liquid level transducer and force transducer, the transducer signal input amplifier circuit is connected with one-chip computer via A / D conversion by serial data bus, the one-chip computerand serial communication interface are connected to digital display circuit and the stabilized voltage power supply circuit is connected in between the circuits at various grades in parallel separately.

Description

1. Technical field [0001] The invention relates to a hydraulic induction volume density meter and its testing method and application, belonging to the field of volume-density testing of objects with irregular shapes. 2. Background technology [0002] At present, in terms of physiological anatomy, pathological anatomy, forensic pathology, and physical anthropology at home and abroad, the method of measuring length × width × height with a manual ruler is still used to express the volume of human organs. Due to the extremely irregular three-dimensional shape of organs, this This volume value is unscientific and inaccurate, and cannot be used to further calculate the density of organ tissues. [0003] According to literature reports and novelty search results, the current main research focuses on the indirect measurement of living organs using CT and B-ultrasound, such as Zhu Haixian, Gu Guangguan, Wang Xintao, etc., a preliminary study on the method of measuring spleen volume b...

Problems solved by technology

While retaining all the information of 2D ultrasound imaging, 3D ultrasound imaging can provide a very vivid and intuitive 3D stereoscopic image, showing the three-dimensional shape, internal structure, surface features, and spatial position relationship of tissue structures, extracting and displaying structures of interest separately, and accurately Measuring volume or volume is helpful for the qualitative, localization and quantitative diagnosis of diseases, but the structure is complex and costly

[0004] In a word, at present, the volume of human organs at home and abroad all adopts a ruler to measure the length, width and height to obtain the volume. According to the novelty search report of the Medical and Health Science and Technology of the Jilin Provincial Institute of Health Information: there is no bibliographical report identical to the content of the present invention.
