Abstract
A method and system for enhancing Doppler spectrum displays is described. Two or more colors are utilized to represent the power scale in the spectral Doppler display. Doppler signals from stronger reflectors of ultrasound, such as cardiac muscle or vessel walls, can then be assigned a different color than Doppler signals from weaker reflectors, such as blood, allowing for better understanding and interpretation of the Doppler spectra.
Claims34
A method of processing Doppler signals, the method comprising:
- determining signal strength of received Doppler signals;
- and
- assigning color to the received Doppler signals in accordance with the strength of the received Doppler signal.
A method of processing Doppler ultrasound signals, the method comprising:
- receiving Doppler ultrasound data that includes strength of a received Doppler ultrasound signal;
- assigning color to the received Doppler ultrasound data in accordance with the strength of the received Doppler ultrasound signal such that different ranges of received signal strengths are assigned different colors.
An ultrasound system comprising:
- an ultrasonic transducer configured to transmit and receive ultrasonic signals from a sample;
- an ultrasound scanner configured to communicate signals to the ultrasonic transducer to be transmitted into the sample, wherein the scanner receives signals from the ultrasonic transducer that were reflected from objects within the sample, the scanner processes the received signals to determine velocity of an object reflecting signals based on Doppler effect and assign color to represent the received signal based on the strength of the received signal;
- and
- a display for displaying the Doppler data that has been assigned color.
An ultrasound system comprising:
- an ultrasonic transducer configured to transmit and receive ultrasonic signals from a sample;
- an ultrasound scanner configured to communicate signals to the ultrasonic transducer to be transmitted into the sample, the scanner receives signals from the ultrasonic transducer that were reflected from objects of the sample;
- a processor configured to processes the received signals to determine a velocity of an object reflecting signals based on Doppler effect and assigning color to represent the received signal based on the strength of the received signal;
- and
- a display for displaying Doppler data that has been assigned color.
A method of representing Doppler signals, the method comprising:
- means for determining signal strength of received Doppler signals;
- and
- means for assigning color to the received Doppler signals in accordance with a strength of the received Doppler signal.
A method of processing Doppler ultrasound signals, the method comprising:
