Abstract:
The present invention proposes an ultrasound system and method of identifying a vessel of a subject. The ultrasound system comprises: an ultrasound probe configured to simultaneously acquire a sequence of ultrasound blood flow data frames (such as a sequence of ultrasound Doppler data frames) and a sequence of ultrasound B-mode data frames of a region of interest including the vessel over a predetermined time period; a blood flow region selecting unit configured to select a blood flow region in the sequence of blood flow data frames; and a vessel segmenting unit configured to segment the vessel in at least one frame of the sequence of ultrasound B-mode data frames based on the selected blood flow region. Since there is no need to manually place any seed point for vessel segmentation any more, the user dependency is reduced and a fast measurement is made possible. Furthermore, since the segmentation of the vessel in a B-mode data frame makes use of information from multiple blood flow data frames, more robust, reliable segmentation can be achieved.
Abstract:
An embodiment of this invention provides an ultrasound device that assesses a bone of a subject in at least two modes comprising a first mode and a second mode. The ultrasound device comprises: a selecting unit configured to select a mode from the at least two modes; a first ultrasound probe configured to transmit an ultrasound signal to the bone; a second ultrasound probe configured to receive the ultrasound signal from the bone; an assessing unit configured to derive a first parameter of the bone based on the selected mode and the ultrasound signal received by the second ultrasound probe; and a coupler being configured to be switched to a first configuration in the first mode and to a second configuration in the second mode. The ultrasound probes are oriented in substantially a same direction in the first configuration, and in substantially an opposite direction in the second configuration.

An embodiment of this invention provides an ultrasound device and a method of assessing a bone of a subject. The ultrasound device assesses a bone of a subject in at least two modes comprising a first mode and a second mode. The ultrasound device comprises: a selecting unit configured to select a mode from the at least two modes; a first ultrasound probe configured to transmit an ultrasound signal to the bone; a second ultrasound probe configured to receive the ultrasound signal from the bone; an assessing unit configured to derive a first parameter indicating one or more characteristics of the bone based on the selected mode and the ultrasound signal received by the second ultrasound probe; and a coupler for coupling the first ultrasound probe and the second ultrasound probe, the coupler being configured to be switched to a first configuration in the first mode and to a second configuration in the second mode. A face of the first ultrasound probe and a face of the second ultrasound probe are oriented in substantially a same direction in the first configuration, and in substantially an opposite direction in the second configuration. An embodiment of this invention improves the flexibility of usage of the ultrasound assessment device.
