METHODS AND APPARATUS TO COMBINE FRAMES OF OVERLAPPING SCANNING SYSTEMS
Methods, apparatus, systems and articles of manufacture to combine frames of overlapping scanning systems are disclosed. An example apparatus includes a time delay controller to determine a first time value and a second time value, the first time value different from the second time value; a capture synchronizer to, in response to the first time value corresponding to a first time, capture a first frame from a first scanning system and, in response to the second time value corresponding to a second time, capture a second frame from a second scanning system; and a capture combiner to combine the first frame and the second frame into a third frame, the third frame including data from the first frame and data from the second frame.
Linear magnetic drive transducer for ultrasound imaging
An ultrasound imaging system uses a magnetic linear motor driven ultrasound scanner, with accurate track and hold operation and/or other motion feedback, to scan a two dimensional or three dimensional area of a sample. The scanner is implemented in a low-power and low-bandwidth handheld device and is connected with a remote image processing system that receives raw data and performs full ultrasound image analysis and creation, allowing the handheld to be used for scanning, pre-processing, and display.
Techniques for determining ultrasound probe motion
The present disclosure relates to extraction of probe motion estimates from acquired ultrasound image frames. Such image-extracted probe motion data can be used alone or in combination with sensed motion data, such as acquired using an inertial measurement unit (IMU). In certain implementations, the image-extracted probe motion can be used to provide or maintain anatomic context in a sequence of images or to provide guidance to a user.
ULTRASONIC IMAGING SYSTEM, ULTRASONIC IMAGING DEVICE, ULTRASONIC IMAGING METHOD, AND IMAGE SYNTHESIZING PROGRAM
An ultrasonic imaging system is provided which can obtain an accurate synthesized image, even if a specimen has a surface with a large curvature. An ultrasonic imaging system may include a probe and processing circuitry. The probe may perform scan of first and second ultrasonic waves different from each other. The processing circuitry may generate a first ultrasonic image based on the first ultrasonic wave and generate a second ultrasonic image based on the second ultrasonic wave. The processing circuitry may calculate a spatial relationship based on two first ultrasonic images at two positions and two second ultrasonic images at the two positions. The processing circuitry may synthesize one of the first and second ultrasonic images at one of the two positions with the one of the first and second ultrasonic images at the other position based on the calculated relationship.
METHODS AND SYSTEMS FOR TRACKING AND GUIDING SENSORS AND INSTRUMENTS
A shared-housing ultrasound transducer and machine-vision camera system is disclosed for registering the transducer's x, y, z position in space and pitch, yaw, and roll orientation with respect to an object, such as a patient's body. The position and orientation are correlated with transducer scan data, and scans of the same region of the object are compared in order to reduce ultrasound artifacts and speckles. The system can be extended to interoperative gamma probes or other non-contact sensor probes and medical instruments. Methods are disclosed for computer or remote guiding of a sensor probe or instrument with respect to saved positions and orientations of the sensor probe.

High speed ultrasonic thick slice imaging by combining slice images with microbeamformer provided in the probe to control steering
An ultrasonic diagnostic imaging system scans a plurality of planar slices in a volumetric region which are parallel to each other. Following detection of the image data of the slices the slice data is combined by projecting the data in the elevation dimension to produce a thick slice image. Combining may be by means of an averaging or maximum intensity detection or weighting process or by raycasting in the elevation dimension in a volumetric rendering process. Thick slice images are displayed at a high frame rate of display by combining a newly acquired slice with slices previously acquired from different elevational planes which were used in a previous combination. A new thick slice image may be produced each time at least one of the slice images is updated by a newly acquired slice. Frame rate is further improved by multiline acquisition of the slices.
STABILIZATION OF ULTRASOUND IMAGES
The invention provides a method of stabilising an ultrasound image, the method comprising generating a composite image of a current image and at least one previous image. The composite image has a region of interest which is stabilised based on at least obtained stabilisation information. Use of a current image and at least one previous image allows a composite image of a larger size to be produced.
Intelligent localized high-resolution imaging of tubulars
A device and method used to image wells and other fluid-carrying tubulars having localized features of interest. The device scans large areas of the tubular first in a low-resolution mode using an ultrasound sensor and in a high-resolution mode using a camera, then identifies areas that contain those localized features with some probability. The device images are stored for further image processing. The two sensors are axially spaced-apart on the device. A computer remote from the imaging device renders a visualization of the tubular and localized features using the optical and ultrasound images.
Method and apparatus for ultrasound image acquisition
Method for ultrasound image acquisition includes defining a fixed frame of reference, with an origin of coordinates within a transmitter of a tracking system; detecting position and orientation of a probe relative to the frame of reference with a probe sensor of the tracking system coupled to the probe; detecting position and orientation of a body relative to the frame of reference with a reference sensor of the tracking system coupled to the body; calculating position and orientation of the probe with respect to the body; acquiring a set of 2D images constituting a 3D by transmitting an ultrasonic beam into the body and receiving echographic signals with the probe; iterating for a predetermined number of 3D image acquisitions; generating a panoramic 3D image by combining the 2D images based on information of position and orientation of the probe relative to the body for each 2D image acquisition.
