Problems solved by technology
[0005] The purpose of the present invention is: in order to solve the problem that the surface temperature of the intrusive probe cannot be measured and verified, the present invention provides a load phantom for measuring the surface temperature of the intrusive ultrasonic probe, as the load of the intrusive ultrasonic probe, in It simulates the measurement of the surface temperature of the ultrasonic probe under the state of use. It has a cylindrical acoustic window in the cavity for the insertion and coupling of the embedded ultrasonic probe, which can ensure the conformal coupling of the radiation surface of the existing various invasive ultrasonic probes. Will not affect the measurement results of the probe surface temperature due to poor coupling

Abstract
The invention provides a load phantom (1) for surface temperature measurement of an intrusive ultrasonic probe. The load phantom (1) structurally comprises a phantom shell, an acoustic-thermal simulated tissue material (7) and a supporting and protection plate (4); the phantom shell is fixedly connected on the protection plate (4), and the phantom shell is filled with the acoustic-thermal simulated tissue material (7); the phantom shell is cylindrical, and comprises a base plate (9), an upper panel (3), a metal cylinder (2) and a cavity opening sleeve (5) and a cavity inside acoustic window (21); the base plate (9) of the phantom shell and the supporting and protection plate (4) are tightly fixed together through a first bolt (10) and a second bolt (11); a middle part of the base plate (9)is provided with a round hole, and the round hole is plugged by a sealing rubber (12); the top of the metal cylinder (2) is provided with the upper panel (3), the cavity opening sleeve (5) and the cavity inside acoustic window (21) are arranged at the round hole of the middle part of the upper panel (3); and a sound absorption lining (8) is adhered at one side of the inner wall of the metal cylinder.
Description
technical field [0001] The invention relates to the technical field of medical device quality detection, in particular to a load phantom used for measuring the surface temperature of an intrusive ultrasonic probe. Background technique [0002] Medical ultrasonic diagnosis-monitoring equipment transmits ultrasonic waves of a certain frequency, intensity and form to designated parts of the human body through ultrasonic probes, receives and processes reflected-scattered echo signals, and then displays the status of the part of the human body in the form of images, graphics, numbers, and sounds. Physiological and pathological information, so as to make judgments on the presence, nature, and degree of diseases and injuries, or a complex system that monitors the parameters of human body signs. However, while the ultrasonic wave is used as an information carrier, it is also a carrier of force and energy. It will act on the tissue with radiation force, sound flow, and heat energy co...
