Embodiment 1

[0058] This embodiment provides an instrument test method to determine the repeatability measurement accuracy of the ultrasonic image instrument. The accuracy here, for example, refers to consistency of multiple repeated measurements. The accuracy of the ultrasound image instrument can reflect the measurement ability of the instrument.

[0059] This method is figure 1 The instrument test equipment 100 is implemented. like image 3 As shown, the method includes steps S3100-S3300 below.

[0060] Step S3100: Getting the instrument With a plurality of first measurements obtained by multiple measurements of a physical indicator for a multiple measurement of a physical indicator of the same region having a particular nominal value.

[0061] Physical indicators are, for example, physical quantities measured by instruments, such as elasticity, sound decay, and the like.

[0062] In general, there may be differences in the true value of the physical indicators of different regions of the sa...

Embodiment 2

[0082] This embodiment provides an instrument test method, and on the basis of the method of the embodiment, the accuracy of the instrument measurement is also tested. The measurement accuracy here, such as consistency between the measured value of the physical indicator and the true value of the imitation tissue mode physical indicator.

[0083] This method is figure 1 The instrument test equipment 100 is implemented. The method includes steps S4100-S4600 below.

[0084] Step S4100: Gets the instrument to make a plurality of first measurements obtained by multiple measurements of a physical indicator for a plurality of measurements of a physical indicator of the same region having a particular nominal value.

[0085] Step S4200: Determine the degree of dispersion of multiple first measurements.

[0086] Step S4300: Determine the repetitive measurement accuracy of the instrument according to the degree of discretization of the first measured value.

[0087] Embodiments of the abov...

Embodiment 3

[0111] This embodiment provides an instrument test method, and on the basis of the method of the embodiment, the accuracy of the instrument measurement is also tested. The measurement accuracy here, such as consistency between the measured value of the physical indicator and the true value of the imitation tissue mode physical indicator. In this embodiment, the measurement accuracy of the instrument is tested to test the measurement accuracy of the instrument in conjunction with different ranges of the physical indicator value of the imitation tissue mode to comprehensively and reasonably determine the measurement ability of the instrument.

[0112] This method is figure 1 The instrument test equipment 100 is implemented. The method includes the following steps S5100-S5600.

[0113] Step S5100: Gets the instrument to perform multiple first measurements obtained by multiple measurements of a physical indicator for multiple measurements of a physical indicator of the same area of ​​...

Abstract

The invention provides an instrument testing method, an instrument testing device and an instrument testing device. The method includes: obtaining a plurality of first measurement values ​​obtained by the instrument through multiple measurements of a certain physical index on the same area of ​​a tissue-mimicking phantom with a specific nominal value; determining the plurality of first measurement values The degree of dispersion of the measured values; according to the degree of dispersion of the first measured value, the repeatability measurement accuracy of the instrument is determined.

Description

Technical field [0001] The present invention relates to the field of ultrasound imaging, and more particularly to an instrument test method, an instrument test device and an instrument test device. Background technique [0002] Ultrasonic image technology can be used to measure the physical properties of organs such as liver, which reflects the health of organs. For example, it is possible to determine whether there is a health problems such as cirrhosis and fatty liver by measuring an indicator of the elasticity of the liver. [0003] For ultrasonic image instruments, it is usually tested with the imitation tissue mold (referred to as an imitation tissue model). For example, using the instrument to measure the elasticity of the imitation tissue and calculate the difference between the elastic nominal value of the tissue model, it is determined to determine the measurement accuracy of the instrument on the elasticity. However, due to the fact that the factory error, changes in th...
