摘要： An illustrative device for creating images based on ultrasonic pulses comprises an ultrasonic transducer configured to transmit and receive ultrasonic pulses; and a mirror comprising at least two facets configured to reflect the ultrasonic pulses, wherein the mirror is configured to rotate. The ultrasonic transducer and the mirror are positioned in a probe head. A first facet of the mirror reflects the ultrasonic pulses from the ultrasonic transducer during a first range of rotation of the mirror and a second facet of the mirror reflects the ultrasonic pulses from the ultrasonic transducer during a second range of rotation of the mirror.

摘要： Methods and systems are provided for an ultrasound probe including a small-angle adjustment element. In one embodiment, the small-angle adjustment element includes a piezoelectric actuator configured to rotate a transducer array of the ultrasound probe in response to electrical signals transmitted to the piezoelectric actuator.

摘要： Ultrasound apparatus or techniques can include obtaining reflected ultrasound echo information, which can be used to construct a two-dimensional or three-dimensional representation of an at least approximately specular reflected target, such as bone. In an example, echo information can be obtained from spatially-overlapping tissue regions, such as using one or more of an array of ultrasonic transducers, or mechanically-scanning one or more ultrasonic transducers. In an example, one or more of a deformable housing or a deformable coupling pad can be used, such as to couple ultrasonic energy between one or more transducers and a tissue region.

摘要： A low power ultrasound system for use in sonography applications, including vascular imaging, is disclosed. The low power ultrasound system includes a base unit having an image processor and a display. An ultrasound probe is operably connected to the base unit. The probe includes a head portion including an array of crystal transducers. A plurality of pulser/receiver modules that cause the transducers to emit ultrasonic transmit pulses are also included in the probe. The pulser/receiver modules are further configured to receive analog signals relating to ultrasonic echo receive pulses detected by the transducers. The probe includes a singular low noise amplifier that amplifies the analog signals, and an analog-to-digital converter that converts the analog signals to a digital signal. A wireless interface is included for enabling the digital signal to be wirelessly transmitted from the probe to the image processor of the base unit.

摘要： The present invention provides an ultrasound imaging system and an ultrasound imaging method for improving the imaging quality of the desired imaging plane in the volume of interest of a subject. According to the present invention, it is possible to directly scan the desired imaging plane by exploiting the capability of a 2D matrix ultrasound transducer and/or the flexibility of the position/orientation of the ultrasound probe. In some cases, the setting parameters of the transducer elements can be adjusted so that the ultrasound signal transmitted from the transducer elements is able to derive ultrasound echo data of the desired imaging plane without moving the probe. In other cases where the desired imaging plane cannot be directly scanned without changing the position/orientation of the ultrasound probe, the position/orientation of the ultrasound probe can be adjusted by means of user interaction, namely by outputting the instruction for guiding the user to move the probe so as to enable direct scanning of the desired imaging plane. In this way, the image of the desired imaging plane is not reconstructed by interpolation of the ultrasound echo data of the plurality of scanning planes (which are determined by the setting parameters of the transducer elements), but instead it is reconstructed from the ultrasound echo data of the desired imaging plane itself. In other words, the desired imaging plane is directly scanned. Thus, the image quality of the desired imaging plane is improved and may help doctors conduct a more accurate diagnosis.
