Tissue mimicking body model for detecting imaging distinguishability of ultrasound echotomography scanning equipment

Abstract

The invention discloses a tissue mimicking body model for detecting imaging distinguishability of ultrasound echotomography scanning equipment. The tissue mimicking body model is in the shape of a truncated cone, and comprises a body model housing, an acoustic window (3), a supporting and protecting plate (6), a plurality of target lines (4), a plurality of simulated niduses (6) and background tissue-mimicking materials (12), wherein the body model housing is manufactured by fixed connecting of an upper panel (2), a lower panel (11) and a supporting plate (14); a sealing space is formed by thebody model housing and the acoustic window (3) which is adhered and fixed to the side surface of the truncated cone; the background tissue-mimicking materials (12) are stuffed in the sealing space; the target lines (4) and the simulated niduses (6) are embedded in the background tissue-mimicking materials (12); each target line and each simulated niduse vertically penetrate from the upper panel (2) to the lower panel (11); an inlet for stuffing the background tissue-mimicking materials (12) is formed in the supporting plate (14); a blocking rubber is adhered to the inlet; and the supporting and protecting plate (6) is fixed outside the supporting plate (14).

Description

technical field [0001] The invention belongs to the field of medical device quality detection, and in particular relates to a tissue imitation phantom used for detection of imaging resolution of ultrasonic tomography equipment. Background technique [0002] B-ultrasound, X-CT, magnetic resonance imaging, and nuclear medicine imaging are the four most practical imaging diagnostic technologies in the contemporary era, and in terms of popularity, B-ultrasound ranks first among the four. Especially under the specific conditions of our country, B-ultrasound technology is not only used in the routine diagnosis of various diseases, but also widely used in the fields of family planning, eugenics and reproductive health. Their performance and quality are not only related to the economic benefits of manufacturers and hospitals, but also affect the health and well-being of the entire Chinese nation, including future generations. It is precisely in view of this situation that the natio...
