Abstract: A system and method for visually assisting an operator of an ultrasound system are provided. In an aspect, the method involves receiving imaging data of an anatomical region using a first coordinate system, the imaging data marked with a landmark for identifying the anatomical region; transforming the imaging data of the anatomical region from the coordinate system to a cylindrical coordinate system; displaying a live ultrasound image of the anatomical region as received from an ultrasound transducer; receiving positional information from the ultrasound transducer corresponding to an alignment point of the anatomical region; and displaying a transformed image from the transformed imaging data of the anatomical region corresponding to the alignment point using the landmark; wherein the transformed image and the live ultrasound image are displayed simultaneously. In another aspect, the method involves generating and transforming a 3D model of the first anatomical regions.

Abstract: A perfusion imaging processing method comprising collecting a plurality of digital images comprising sequential B-Mode micro-ultrasound reflectivity data, calculating decorrelation trends of autocorrelated data to determine blood flow and perfusion level, reducing the noise content in the data using the decorrelation trends, and/or forming a visual representation based on the decorrelation trends. The present system and method provides an ultrasonic imaging system and method which provides perfusion data without requiring the use of an injected contrast agent.

Abstract: A signal processing pathway for an ultrasonic imaging device is provided. The signal processing pathway is configured to operate in a frequency range of 1 MHz to 40 MHz inclusive and a voltage range of ?80V to +80V inclusive.

Abstract: The present invention provides improved medical imaging apparatuses, systems and methods, especially those using ultrasonography. For example, an imaging system can include a transducer, a scanner, a signal processing unit, and a display unit. The scanner, coupled to the transducer, can convert analog signals to a plurality of digital signals. The signal processing unit, coupled to the scanner, can be configured to: receive the plurality of digital signals; multiply a first magnitude estimate of the plurality of digital signals by a probability that an actual magnitude of the plurality of digital signals is greater than zero to determine a second magnitude; and form an image based on the second magnitude estimate. The display unit displays the image. The present invention also provides for products produced by the methods of the present invention and for apparatuses used to perform the methods of the present invention.
