| 摘要 |
<p>The invention concerns a measuring device (3) for generating a differential pressure representative of the flow rate of a gas flow for medical imaging, comprising; a central body (8) provided with longitudinal channels (4) in communication with an inlet (5) and an outlet (6) of the gas stream, a casing (9) surrounding the central body, and seals (7a, 7b, 7c, 7d) delimiting a first space (10) for measuring an upstream pressure and a second space (11) for measuring a downstream pressure, each in communication with at least one of the longitudinal channels, and a third space (12) for heating up the central body. The invention also concerns a device for detecting the position of a moving area of the body of a patient, analysed by medical imaging, and a medical imaging apparatus incorporating such a detection device.</p> |
