Embodiment

[0023] Such as figure 1 with figure 2 As shown in the structure diagram of the device, this embodiment discloses a device for verifying the accuracy of an ultrasonic imaging arc measurement system. The device includes a water tank 1, a bottom plate 2, a plurality of supporting rods 3 and a plurality of small balls 4.

[0024] One end of the support thin rod 3 is arranged on the bottom plate 2 and arranged in an arc. The arc and the radius and chord length of the arc can refer to the attached figure 1 As shown by the dashed line, the center of the arc can be outside the bottom plate 2.

[0025] The material density of the bottom plate 2 is greater than the density of water or ultrasonic couplant, which can ensure that the bottom plate 2 is stably placed at the bottom of the sink and will not deform when exposed to water or ultrasonic couplant.

[0026] The thin supporting rods 3 are evenly distributed on the arc of the bottom plate 2 in a uniform arc, and the diameter of the thin su...

Abstract

The invention discloses an apparatus for verifying accuracy of an ultrasonic imaging arc measurement system, comprising a water tank (1), a bottom plate (2), a plurality of thin support rods (3) and a plurality of bobbles (4); the bobbles (4) are fixed to one ends of the thin support rods (3) respectively, the other ends of the thin support rods (3) are arranged on the bottom plate (2) in arc arrangement; the water tank (1) is of trough structure filled with water or ultrasonic coupler, the bottom plate (2) is arranged in the trough structure of the water tank (1), the bottom surface of a trough is sized to sufficiently receive the bottom plate (2), and enough space is reserved to facilitate moving of an ultrasonic prober to perform scanning imaging; the apparatus allows the accuracy of the ultrasonic imaging arc measurement system to be verified such that quantitative analysis is provided for precision and accuracy; a manufacture method is simple, convenient to perform and is highly practical.

Description

Technical field [0001] The invention relates to the technical field of medical ultrasound imaging result measurement, in particular to an accuracy verification device for an ultrasound imaging radian measurement system. Background technique [0002] Medical ultrasound imaging is one of the important diagnostic methods in modern clinical medicine, but the field of ultrasound imaging is limited by the width of the probe. To solve this problem, Weng et al. proposed Extendedfield-of-view ultrasound in 1996. It collects a series of ultrasound images and uses image registration technology to stitch together to form an image with a larger observation field. , Convenient for doctors to diagnose. The results of traditional wide-view imaging technology in detecting tissues with a large degree of curvature are different from the actual situation of the tissue. A new method is to collect a series of ultrasound images and their position information, and then transform these images to Carry ...
