摘要： Ultrasound scanners that are initialized and placed to the side in a sterile bag for use in a sterile environment may suffer overheating and cut out early, because the bag represents a poor cooling environment. The rate of increase in temperature of a scanner is monitored and a determination is made as to whether the scanner is in a regular environment or a poor cooling environment. If the scanner is in a poor cooling environment, the scanner is switched from a regular state of operation to a poor cooling state of operation. In the poor cooling state of operation, the scanner settings consume less power and generate less heat on the whole than the regular scanner settings. The scanner reverts to higher power settings as and when needed to perform the desired scan. The user interface on an associated display device also changes in response to the scanner entering the poor cooling state of operation.

摘要： This disclosure relates to methods and apparatus for performing at least three modes of ultrasound imaging using a single ultrasound transducer. In a first mode, transducer elements are activated so that ultrasound signals are transmitted from the contact surface at one or more directions normal to the contact surface. In a second mode, a first subset of the transducer elements are activated so that parallel ultrasound signals are transmitted from the contact surface. In a third mode, a second subset of the transducer elements are activated so that ultrasound signals are steered from the second subset of transducer elements.

摘要： An ultrasound scanner in a spectral Doppler mode, in which a corresponding two-dimensional (2D) ultrasound imaging mode (e.g., B-mode) image is frozen, is switched temporarily to the 2D-mode in response to a continuous contact on a touchscreen. During the continuous contact, the spectral Doppler mode is interrupted, the 2D-mode image becomes live, and the gate for the spectral Doppler mode may be adjusted by a movement of the continuous contact on the touchscreen. Upon termination of the continuous contact, the system reverts back to the spectral Doppler mode, which now operates within the adjusted gate, and the 2D-mode image is frozen. A brief contact may be used to check the position of the gate against a live 2D-mode image without adjusting it.

摘要： An ultrasound imaging system including an ultrasound imaging apparatus operable to acquire ultrasound image data and an add-on vibration inducing device operable to generate shear waves. The add-on vibration inducing device is connected cordlessly to the ultrasound imaging apparatus. The add-on vibration inducing device can be powered and controlled by the ultrasound imaging apparatus. The add-on vibration inducing device includes a connector to scanner which connects cordlessly to a power connector on the ultrasound imaging apparatus for transmitting the power and the control signals from the ultrasound imaging apparatus to the add-on vibration inducing device. The ultrasound imaging apparatus can be used separately from the add-on vibration inducing device for ultrasound imaging procedures and the add-on vibration inducing device can be easily mounted on the ultrasound imaging apparatus when the user wishes to perform an elastography diagnostic procedure.
