Embodiment Construction

[0028] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0029] According to the quality system requirements of medical device manufacturing enterprises and professional quality inspection institutions, all measuring instruments used for quality inspection must be regularly verified or calibrated. Ultrasonic tissue imitation phantoms are "tissue substitutes". Because they directly affect the quality judgment of ultrasonic diagnostic equipment, the rules of regular inspection and comparison have been formed since the end of the last century, which is recognized and followed by relevant circles. The product corresponding to the present invention is used for quality detection and evaluation of ultrasonic tomographic scanning equipment, and for detection and evaluation of transmission mode of ultrasonic imaging equipment.

[0030] Such as figure 1 with figure 2 As shown, the present invention propo...

Abstract

The invention discloses a tissue mimicking phantom for detecting a transmission imaging pattern of ultrasound tomography equipment. The tissue mimicking phantom is cylindrical and comprises an upper panel (2), a lower panel (6), an acoustic window (3), a plurality of targets (4) and background tissue-mimicking materials (9), wherein a sealed space is formed by the upper panel (2), the lower panel(6) and the acoustic window (3) which is adhered and fixed to the side surface of the cylinder; the background tissue-mimicking materials (9) is stuffed in the sealed space; the targets (4) penetratethrough the upper panel (2) and the lower panel (6), and are embedded in the background tissue-mimicking materials (9); an inlet for stuffing the background tissue-mimicking materials (9) is formed inthe lower panel (6); and a block rubber is adhered to the inlet. The tissue mimicking phantom disclosed by the invention can be used for detecting and evaluating the transmission imaging pattern of the ultrasound tomography equipment.

Description

technical field [0001] The invention belongs to the field of quality detection of medical equipment, and in particular relates to a tissue imitation phantom used for detection of transmission imaging modes of ultrasonic tomographic scanning 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 ...
