Respiration gate-controlled inflation system, inflation method and medical imaging equipment

Abstract

The invention discloses a respiration gate-controlled inflation system, respiration gate-controlled inflation method and medical imaging equipment. The system comprises an air pump, a first controller, a first pressure sensor and an inflation passage, wherein the first controller is connected with the air pump, the air outlet of the air pump is communicated with one end of the inflation passage, and the other end of the inflation passage is used to be communicated with an air cell; and the first pressure sensor is arranged on the inflation passage, the output end of the first pressure sensor is coupled to the first controller which controls the air pump to stop inflating according to the pressure detected by the first pressure sensor, namely controlling the air pump to stop inflating when the pressure detected by the first pressure sensor reaches a first pressure value. The inflation system and the inflation method have the advantages that: medical care personnel do not have to inflate the air cell manually, and the working efficiency is improved; and as the reference pressure in the air cell is monitored and controlled, the output signal is optimized and the amplitude and accuracy of the signal are not seriously affected.

Description

【Technical field】 [0001] The invention relates to medical equipment, in particular to a respiratory gating system. 【Background technique】 [0002] In some medical imaging equipment, its image is easily disturbed by respiratory movement, such as MRI (magnetic resonance imaging), CT (computed tomography). The industry generally adopts the technical avoidance and compensation of respiratory gating. [0003] Respiratory gating technology generally achieves the purpose of measuring respiratory movement by measuring the pressure change of the inflated airbag attached to the human body with respiratory movement. For example, the respiratory gating system disclosed in Chinese patent application No. 200810055806.5. At present, the start and stop of inflation of the airbag are controlled manually, and when the medical staff judges based on experience that the pressure has been inflated to the required pressure, the inflation is stopped. In this inflation mode, the reference pressur...

AI Technical Summary

Problems solved by technology

In this inflation mode, the reference pressure of the airbag (that is, the preset inflation pressure in the airbag) is not easy to control, thus affecting the amplitude and accuracy of the signal
