Abstract

The invention discloses a low-noise digital CT audio interaction system and a control method, which adopt a set of circuit system different from a conventional audio control scheme and are matched with a power-on method of a CT system and a time sequence control method in different use states. The problems of noise at the moment of CT power-on, howling avoidance of intercommunication in a shielding room and strong electromagnetic interference noise during CT scanning are solved. The system has the advantages of low noise and strong anti-interference capability.

Description

technical field [0001] The present invention relates to the technical field of medical devices, and more specifically relates to a low-noise digital CT audio interactive system and a control method. Background technique [0002] In the CT voice interaction, due to the need to realize the intercom and automatically remind the patient to inhale and hold the breath at a specific scanning moment, the current CT intercom system often needs to use a PC or a self-made audio storage device to assist in realizing the function of automatically playing voice. However, in the overall audio system, multiple audio analog signals are collected together, the current impact of the CT system at the moment of power-on and the high-power relay pull-in, etc., resulting in more audio noise and poor anti-electromagnetic interference ability. Poor, even cause howling when the interference is large. Existing technical solutions often use analog signals to directly pick up the sound and amplify it a...
