    • An ultrasonograph having a vascular diameter measurement means for taking an ultrasonic tomography image of a blood vessel and then measuring a vascular diameter based on the image, including: an ultrasonic probe 11 having an ultrasonic oscillator 11a for an ultrasonic beam scan, the oscillator being rotatable in the direction orthogonal to the ultrasonic beam's scan direction; a multi-section imaging means for tilting the oscillator 11a at predetermined intervals to perform an ultrasonic beam scan by the oscillator 11a at each position in order to take a tomography image of the blood vessel 50 at a plurality of sections; an imaging position determiner for comparing the results of the measurement of the vascular diameter based on each taken tomography image, and determining the position where an image presenting the largest vascular diameter has been taken as the largest vascular diameter imaging position; and a largest vascular diameter acquisition means for tilting the oscillator 11a to the position determined by the imaging position determiner. This saves the trouble of manually fixing the probe's displacement due to a rapid decompression in releasing the avascularization, which achieves a smooth % FMD measurement.

    • The schedule memory unit 23 memorizes a time schedule set in advance for saving images. The avascularization unit 30 compresses the subject's brachial region to avascularize the brachial artery, releases the avascularization after a predetermined period of time, and simultaneously transmits a decompression start signal to the controller 17. The controller 17 stores an ultrasonic image in the image storage unit 22 at a point in time when a period of time specified by the time schedule has elapsed after the decompression start signal was received. The vascular diameter measuring unit 18 determines the vascular diameters based on the ultrasonic tomography images of a blood vessel at rest and after the release of the avascularization which are stored in the image storage unit 22. Based on those diameter values, the largest vascular diameter deducing unit 20 and the % FMD calculation unit 21 perform the deduction of the largest after-release vascular diameter and the calculation of the % FMD, respectively. Therefore, after the avascularization is started, it is possible to automatically perform the process from saving a measurement image to the calculation of the % FMD without the operator's aid. Accordingly, the operator's inconvenience in performing a % FMD can be significantly decreased.
    • 时间表存储单元23存储预先设置的用于保存图像的时间表。 血管化单元30压缩受试者的肱动脉区域以使肱动脉血管化,在预定时间段之后释放血运重建,同时将减压开始信号发送到控制器17.控制器17将超声图像存储在图像存储单元22中 在接收到解压缩开始信号之后经过时间表指定的时间段的时间点。 血管直径测量单元18基于存储在图像存储单元22中的静止时的血管的静脉和释放之后的血管的超声断层摄影图像来确定血管直径。基于这些直径值,推导最大的血管直径 单元20和%FMD计算单元21分别执行最大的释放后血管直径和%FMD的计算。 因此,在开始血运重建之后,无需操作人员的帮助,可以自动执行将测量图像保存到%FMD的计算中的处理。 因此,操作者在执行%FMD时的不便可以显着降低。
