20130237826 | PRECISION ULTRASONIC SCANNER FOR BODY PARTS WITH EXTENDED IMAGING DEPTH - A method and apparatus are disclosed for performing an ultrasound scan on a body part and specifically for a portable instrument which directly attaches to the surface of the body. This apparatus provides very high resolution images and greatly increased depth of imaging for high resolution ultrasound of targeted subsurface body tissues with ultrasound image resolution far superior to that of known state of the art ultrasound instruments. Targeted tissues could include but not be limited to joints, ocular structures, and internal organs. | 09-12-2013 |
20140058266 | Ultrasound Imaging System Memory Architecture - A multiple aperture ultrasound imaging system may be configured to store raw, un-beamformed echo data. Stored echo data may be retrieved and re-beamformed using modified parameters in order to enhance the image or to reveal information that was not visible or not discernible in an original image. Raw echo data may also be transmitted over a network and beamformed by a remote device that is not physically proximate to the probe performing imaging. Such systems may allow physicians or other practitioners to manipulate echo data as though they were imaging the patient directly, even without the patient being present. Many unique diagnostic opportunities are made possible by such systems and methods. | 02-27-2014 |
20160030000 | ULTRASOUND WAVEFORM TOMOGRAPHY METHOD AND SYSTEM - A method and system for generating an enhanced image of a volume of tissue, the method comprising: emitting acoustic waveforms toward the volume of tissue; detecting a set of acoustic signals derived from acoustic waveforms interacting with the volume of tissue; generating, from the set of acoustic signals, an initial model representing a distribution of an acoustomechanical parameter across a region of the volume of tissue; extracting a set of frequency components, from the set of acoustic signals; generating a first simulated wavefield with a first frequency component of the set of frequency components; generating an updated model of the initial model with the first simulated wavefield; iteratively refining the updated model with a set of simulated wavefields associated with the set of frequency components until a threshold condition is satisfied, thereby producing a final model; and generating the enhanced image from the final model of the volume of tissue. | 02-04-2016 |
