Abstract: Certain aspects relate to systems and techniques for navigation path tracing. In one aspect, a system displays a preoperative model of a luminal network is displayed. The system determines a position of an instrument within the luminal network relative to the preoperative model. Based on the position of the instrument relative to the preoperative model, the system determines whether to enter a path tracing mode. In path tracing mode the system displays visual indicia indicative of a path of the instrument with respect to the displayed preoperative model. The visual indicia may be used to visual the navigation path of the instrument and/or to extend the preoperative model.

Abstract: For shear wave imaging with ultrasound, the apparent pulse repetition frequency is increased by combining displacements from different lateral locations. Different combinations based on different shear wave velocities and corresponding time shifts and/or attenuations and corresponding scalings are tested to find a smooth displacement profile for the combination. Once the smooth displacement profile is found, the corresponding shear wave velocity is estimated or determined.

Abstract: A system and method for ultrasound imaging may involve the use of an ultrasound probe and a processor coupled to the probe and to a source of previously-acquired ultrasound image data. The processor may be configured to receive patient identification information (e.g., responsive to user input and/or supplemented by additional information such a photo of the patient), to determine whether the patient identification information identifies a recurring patient, and if so, to retrieve, from the source of previously-acquired ultrasound image data, previous ultrasound images associated with the recurring patient. The processor may be further configured to generate a current ultrasound image based on signals received from the prove and to apply a neural network to the current ultrasound image and the previous ultrasound images to identify a matching pair of images, such that imaging settings from the matched previous image may be applied to the system for subsequent imaging.

Abstract: An ultrasound automatic scanning system according to an embodiment includes an ultrasound probe, a mechanical mechanism, and processing circuitry. The ultrasound probe transmits and receives ultrasonic wave. The mechanical mechanism holds and moves the ultrasound probe while an ultrasonic-wave transmission-reception surface of the ultrasound probe is pointed to a subject. The processing circuitry acquires a distance between a body surface of the subject and the ultrasonic-wave transmission-reception surface of the ultrasound probe based on reflected wave data collected while the ultrasound probe is moved by the mechanical mechanism. The processing circuitry generates, based on information of the distance, locus information of movement of the ultrasound probe when ultrasound scanning is executed on the subject. The mechanical mechanism executes ultrasound scanning on the subject by moving the ultrasound probe based on the locus information generated by the processing circuitry.

Abstract: An acoustic imaging system responsive to an acoustic wave emitted from an object is disclosed. The system detects a deflection angle of an electromagnetic probe beam as it passes through a coupling element. The coupling element also couples the acoustic wave emitted from the object to an acoustic detector. The probe beam deflection angle is related to an angle of propagation of the acoustic wave through the coupling element. A filtering unit is configured to remove components of the signal from the acoustic detector that are outside of a range of angles, thereby improving the angular resolution of the acoustic detector. The acoustic wave may be generated by an acoustic source, such as an ultrasound transmitter, or an electromagnetic source such as a laser.

Embodiments may construct a 3-D surface model from stereo images, and will estimate optical properties of the target using images taken in patterned light or using other approximations obtained from white light exposures. Hyperspectral images taken under stimulus light are displayed as fluorescent images, and corrected for optical properties of tissue to provide quantitative maps of fluorophore concentration. Spectral information from hyperspectral images is processed to provide depth of fluorophore below the tissue surface. Quantitative images of fluorescence at depth are also prepared.
