Abstract: A method for simultaneously performing blood flow Doppler imaging and pulse Doppler imaging includes: sequentially transmitting each transmission sequence group including multiple blood flow sequences and a B-mode sequence thereafter; sequentially receiving a first echo signal group reflected by a tissue area of interest in response to the blood flow sequence; sequentially performing beam composition on the first echo signal group corresponding to the blood flow sequence transmitted each time, to obtain a first multi-beam corresponding thereto; sequentially performing wall filtering on the first multi-beam corresponding to the blood flow sequence transmitted each time, to obtain a second multi-beam corresponding thereto, wherein the second multi-beam is a multi-beam representing a blood flow signal in the first multi-beam; and performing a blood-flow-mode imaging process and a blood flow spectrum imaging process based on sequentially obtained second multi-beams.

Abstract: Described herein is a method of registering a medical image of a subject with a 3D model of a subject, including calibrating the 3D model globally by aligning markers on the subject with corresponding markers on the 3D model; and calibrating the 3D model locally by aligning a scanning image of an internal structure of the subject with a corresponding internal structure of the 3D model. Also described herein is an apparatus of performing the method.

Abstract: A method and a device for simultaneously carrying out blood flow Doppler imaging and pulse Doppler imaging, said method comprising: taking transmitting a B pattern sequence once and then transmitting blood flow sequences for multiple times as a transmission sequence group, and transmitting said transmission sequence group in sequence (S101); for each transmission sequence group, sequentially receiving a first echo signal group reflected by a tissue area of interest in response to each transmitted blood flow sequence (S102); sequentially performing beam composition on the first echo signal group corresponding to the blood flow sequence transmitted each time (S103); sequentially performing wall filtering on a first multiple beam corresponding to the blood flow sequence transmitted each time, and obtaining a second multiple beam corresponding to the blood flow sequence transmitted each time (S104); and performing a blood flow pattern imaging process and a blood flow spectrum imaging process according to the subs

Abstract: Techniques and examples pertaining to registering a medical image of a patient with an anatomical model of the patient are described. A processor of an apparatus may calculate a mapping matrix between a real space and a virtual space using one or more mapping objects. The processor may receive data indicating a physical position of a probe relative to the patient. The processor may subsequently determine a virtual position of the probe in the virtual space based on the mapping matrix such that the virtual position as defined in the virtual space corresponds to the physical position in the real space. The processor may then determine a cut plane of the anatomical model, wherein the medical image may represent an anatomical cross-section of the patient at the cut plane.

Abstract: A method and system of imaging of a vessel is provided. The system can include a matrix transducer array (120) for transmitting ultrasonic waves into a region of a body having a vessel and receiving echoes in response, where the echoes are associated with blood flow through the vessel; and a processor (100) operably coupled to the matrix transducer array. The processor can adjust positions of sample volumes (250) associated with the echoes. The processor can electronically steers the ultrasonic waves at one or more of the positions of the sample volumes. The processor can determine a wall of the vessel at each of the positions of the sample volumes based on a Doppler spectrum captured at each of the positions of the sample volumes. Other embodiments are disclosed.
