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.
Claims17
An imaging processing method comprising:
- processing a plurality of digital images comprising sequential B-Mode ultrasound reflectivity data;
- calculating decorrelation trends of autocorrelated data to determine a perfusion level, including fluid flow, through tissue;
- reducing noise content in the autocorrelated data using the decorrelation trends;
- and
- forming a visual representation of the perfusion level based on the decorrelation trends.
A perfusion imaging system comprising:
- a high frequency ultrasound transducer for collecting a plurality of digital images comprising sequential B-Mode ultrasound reflectivity data;
- a signal processing unit, operatively connected to the transducer, the signal processing unit configured to calculate decorrelation trends of autocorrelated data to determine a perfusion level, including fluid flow, through tissue;
- reducing noise content in the autocorrelated data using the decorrelation trends;
- and
- forming a visual representation of the perfusion level based on the decorrelation trends.
A non-transitory computer readable storage medium, comprising executable instructions that when executed by a processor cause the processor to:
- process a plurality of digital images comprising sequential B-Mode ultrasound reflectivity data obtained using a micro-ultrasound;
- calculate decorrelation trends of autocorrelated data to determine a perfusion level, including fluid flow, through tissue;
- reduce noise content in the ultrasound data using the decorrelation trends;
- and
- form a visual representation of the perfusion level based on the decorrelation trends.
