Summary:A device (100) for determining a physiological parameter is disclosed, the device comprising an elongate magnetic probe (102, 610, 702), a drive coil (104) partially arranged around the elongate magnetic probe, a measurement coil (106, 602, 708, 1004) comprising at least 5 first and second sections, and a controller (108). The controller is configured to: selectively energize the drive coil to generate a magnetic force to initiate movement of the elongated magnetic probe in the direction of the first end (102A); measuring a first induced voltage value and a common induced voltage value; determining a locator value as a function of time; 10 mapping locator values as a function of time from the time domain to the spatial domain and calculating a first velocity profile of the elongated magnetic probe from the spatial domain locator values; and determining a physiological parameter using the calculated first velocity profile of the elongated magnetic probe. 公开了一种用于确定生理参数的设备(100)，该设备包括细长磁性探针(102，610，702)、部分地布置成围绕细
