ULTRASONIC IMAGING APPARATUS AND A METHOD OF OBTAINING ULTRASONIC IMAGES
The Journal of the Acoustical Society of America, 2013An ultrasonic probe and a transmitter/receiver scan a 3D region using ultrasonic beams by raising the scanning line density of the transmission of ultrasonic beams for a region of interest compared to the scanning line density of the transmission of ultrasonic beams for regions other than the region of interest among the 3D regions. An image-generating

Dynamic focussing and ultrasonic imaging
ICASSP '82. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005Ultrasonic imaging in B echography requires high resolution over the entire scanning zone. Phased array transducers in conjunction with analogical shift registers (CCD) allow sector scanning and dynamic focussing. Working within this framework a measurement instrument has been devised to evaluate the influence of the different parameters on the image.

Methods for ultrasonic imaging of the heart
Ultrasound in Medicine & Biology, 1976Abstract Ultrasound imaging of the heart is divided into one-dimensional methods currently in use, preliminary techniques which have been developed for two-dimensional static and motion imaging, those techniques currently under development for two-dimensional motion imaging, and goals which appear achievable and which would appear to lead to an ...

Classification of Follicles by Ultrasonic Images
2018 IEEE International Conference on Systems, Man, and Cybernetics (SMC), 2018In this paper, we describe a method for extracting features for classifying "with egg" or "no egg" in follicles from ultrasonic images during oviposition surgery. In the previous research, it was suggested that classification could be preformed by using the deformation at the time of stabbing a follicle as a feature value.

Multidimensional ultrasonic imaging for cardiology
Proceedings of the IEEE, 1988Previous extensions of two-dimensional ultrasonic imaging to three dimensions used lattice diagrams which give measurement information, but no anatomic detail. The authors conducted three sets of experiments to test the hypothesis that complete acoustic backscatter data should be retained to produce useful information about heart structure and function.

Ultrasonic imaging apparatus and method of forming an ultrasonic image of an object
The Journal of the Acoustical Society of America, 1989An ultrasonic imaging apparatus and method of forming an image of an acoustic image of an object employing the aperture synthesis technique, in which at least one partial aperture for accommodating a predetermined number of successive transducers is established and applied to a transducer array to select the predetermined number of successive ...

Ultrasonic Transmission Speckle Imaging
Ultrasonic Imaging, 1981Speckle interferometry, as developed during the past decade for optical astronomy, is adapted to ultrasonic imaging through water and animal tissue. Experimental results are presented illustrating not only Labeyrie's original idea, but also speckle holography and our recently devised shift-and-add technique.

Ultrasonic Reflex Transmission Imaging
Ultrasonic Imaging, 1985Reflex Transmission Imaging (RTI) is a new imaging method by which orthographic transmission images can be made using augmented B-mode equipment. Conventional transmission imaging requires acoustic coupling to large areas on both sides of the body, whereas RTI can be performed from one side with a single, small transducer probe.

Ultrasonic imaging of molecular targets
Basic Research in Cardiology, 2008Today nuclear medicine is the only modality that is clinically successful in molecular imaging. However, other modalities compete with its excellent sensitivity in imaging molecular targets. In the last 10 years ultrasound imaging has shown the potential to provide sufficiently high sensitivity for the molecular imaging of vascular targets.
