Problems solved by technology

[0003] When a patient undergoes a thoracic and abdominal examination, because the movement of the abdominal organs is superimposed on the contraction of the heart, it will cause displacement or motion blur to the image. Uniform and consistent, and when necessary, carry out breath-holding cooperation according to the doctor's requirements; however, some patients cannot adjust the breathing rate well due to factors such as tension during the examination, and cooperate with the doctor to adjust the breathing, so that the breathing rate is disordered, and the abdominal wall follows the breathing. Inconsistencies in the frequency and amplitude of the ups and downs of the undulating motion will affect the quality of the inspection image, cause artifacts in the inspection results, affect the reference value of the image in subsequent analysis and diagnosis, and may even lead to the failure of the inspection. Therefore, patients are required to simulate exercises before the actual inspection. The control of one's own breathing makes the breathing smooth and regular, thus fully ensuring the accuracy and precision of the examination results; and unqualified breathing also makes the MRI examination acquisition time longer and reduces the use efficiency of the equipment

Abstract

The invention discloses an auxiliary training system used before MR and CT examination. The auxiliary training system comprises a respiratory training instrument. The respiratory training instrument comprises a simulated respiratory channel, a flow sensor and a processor. The flow sensor is used for collecting data of breathing airflow flowing through the simulated breathing channel; the processoris connected with the flow sensor through the ADC conversion module; an upper computer interface comprises a training mode, a suffocation mode and an adaptation mode; when the processor receives a training mode instruction, the processor receives respiratory airflow data sampled by the flow sensor and the ADC conversion module, and analyzes and calculates the frequency and amplitude of respiratory airflow according to the respiratory airflow data; whether respiration is qualified or not is judged; by means of the training mode, a subject can practice breathing, control over breathing of the subject is enhanced in combination with the breathing intensity and the breathing frequency, breathing becomes stable and regular, and therefore the accuracy and precision of an examination result arefully guaranteed.

Description

technical field [0001] The invention relates to the technical field of medical examination, in particular to an auxiliary training system for MR and CT examinations. Background technique [0002] MR examination is magnetic resonance examination. Both magnetic resonance and CT examination are a kind of advanced medical imaging examination technology in modern times. Magnetic resonance technology uses the principle of human biological magnetic spin and magnetic resonance phenomenon to image, and there is no nuclear radiation phenomenon and radioactive substances. , has no radiation hazards to the human body, especially has excellent tissue contrast and spatial resolution in soft tissue inspection, and has been widely used in clinical medicine; CT scans a certain thickness of a certain part of the human body with X-ray beams. The X-rays that pass through this layer are received by the detector, converted into visible light, converted from photoelectricity into electrical signal...
