Propeller for angiography detection die body

Abstract

The invention discloses a propeller for an angiography detection die body. The propeller comprises a propulsion device and a remote control device; the propulsion device comprises a casing and an electric push rod arranged in the casing, a through hole is formed in the side wall of the casing, and the electric push rod can stretch out along the through hole; the remote control device comprises a handheld remote control transmitter and a remote control receiver, the handheld remote control transmitter comprises an input button, a remote control coding module and a transmitting antenna, and theinput button is connected with the transmitting antenna through the remote control coding module; the remote control receiver is arranged in the casing and comprises a receiving antenna and a receiving circuit, and the receiving circuit is in control connection with the electric push rod. The propeller is simple in structure and convenient to operate, detecting personnel can control the propellerto push the die body outdoors to continuously expose the die body, the influence of rays on the detecting personnel is reduced accordingly, and the motion artifact generated by manual operation can beavoided at the same time.

Description

technical field [0001] The invention relates to a propulsion device for an angiography detection phantom. Background technique [0002] Angiography is a routine examination performed by cardiovascular patients nowadays. For angiography, a contrast agent is injected into the blood vessels. Because X-rays do not penetrate the contrast agent easily, the blood mixed with the contrast agent will be seen more clearly. The commonly used angiographic contrast agent is iodine reagent. Angiography can accurately reflect the location and degree of vascular lesions. From the results of multiple consecutive images, the sequence of blood flow containing contrast agent can also be seen, so as to understand the physiological and anatomical changes of the heart and large blood vessels. It is a kind of Valuable method for diagnosing cardiovascular disease. However, there are serious background interferences in ordinary angiographic images, such as bones, muscles, and air spaces, etc., whic...

Problems solved by technology

[0006] In the past, when DSA system subtraction performance is tested, there are generally two methods. One is to expose the light outside the room, then enter the room to push the phantom forward for a certain distance, and then expose again outside the room. Trouble, the other is that the operator manually operates the movement of the phantom when the X-ray machine is turned on. The inspectors are not only exposed to X-ray radiation, which affects the health of the inspectors, but also affects the instability of the manual propulsion speed.
