ULTRASOUND DIAGNOSTIC DEVICE AND METHOD FOR CONTROLLING ULTRASOUND DIAGNOSTIC DEVICE |
摘要 |
An ultrasound diagnostic device to which an ultrasound probe is connectable, measuring an IMT of a vascular wall in a carotid artery, includes: a transmission-reception processing unit supplying a transmission signal causing the ultrasound probe to transmit an ultrasound to short-axis cross-sections along the carotid artery, and receiving a signal based on a reflected ultrasound and generating a reception signal for frames at each position; a two-dimensional image generation unit generating two-dimensional images corresponding to the frames; a bulb boundary detection unit measuring a perimeter or area of the vascular wall in each image, and detecting a boundary between a CCA and a CCA bulb from the perimeter or area; and position information indicating a position where each image is acquired; a ROI determination unit determining a ROI defining an IMT measurement range with respect to the boundary; and an IMT measurement unit measuring the IMT within the images. |

1. An ultrasound diagnostic device to which an ultrasound probe is connectable, measuring an IMT of a vascular wall in a carotid artery, comprising:
a transmission and reception processing unit performing a transmission process of supplying a transmission signal for causing the ultrasound probe to transmit an ultrasound to a short-axis cross-section at a plurality of different positions along the carotid artery, and a reception process of receiving a signal based on a reflected ultrasound received by the ultrasound probe from the carotid artery and generating a reception signal for a plurality of frames each corresponding to the short-axis cross-section at one of the different positions; a two-dimensional image generation unit generating a plurality of two-dimensional images each corresponding to one of the frames, based on the reception signal for each of the frames; a bulb boundary detection unit measuring one or more of a perimeter and a cross-sectional area of the vascular wall in the carotid artery according to the short-axis cross-section in each of the two-dimensional images, and detecting a boundary between a common carotid artery and a common carotid artery bulb according to: at least one of the perimeter and the cross-sectional area; and position information indicating a respective position along the carotid artery where each of the two-dimensional images is acquired; a ROI determination unit determining a ROI that defines a measurement range for measuring the IMT, with respect to the boundary; and an IMT measurement unit measuring the IMT in at least one of the two-dimensional images in the ROI. |
