A contrast enhanced ultrasound imaging method, comprising:
- transmitting unfocused waves to the a target region containing microbubbles in multiple angles;
- receiving echo signals of the unfocused waves transmitted in the multiple angles;
- selecting echo signals corresponding to a first number of angles from the echo signals of the unfocused waves transmitted in the multiple angles to obtain a first group of selected echo signals;
- selecting echo signals corresponding to a second number of angles from the echo signals of the unfocused waves transmitted in the multiple angles to obtain a second group of selected echo signals, wherein the first number is greater than the second number;
- generating a first group of contrast enhanced image according to the first group of selected echo signals;
- generating a second group of contrast enhanced image according to the second group of selected echo signals;
- color-coding the first group of contrast enhanced image with a first color;
- color-coding the second group of contrast enhanced image with a second color;
- and
- displaying the color-coded contrast enhanced images.
An ultrasound imaging system, comprising:
- a transducer;
- a transmitting circuit which excites the transducer to transmit unfocused waves to a target region containing microbubbles in multiple angles;
- a receiving circuit which receives echo signals of the unfocused waves transmitted in the multiple angles through the transducer;
- a processor which:
- selects echo signals corresponding to a first number of angles in the multiple angles from the echo signals of the unfocused waves transmitted in the multiple angles to obtain a first group of selected echo signals;
- selects echo signals corresponding to a second number of angles in the multiple angles from the echo signals of the unfocused waves transmitted in the multiple angles to obtain a second group of selected echo signals;
- generates a first group of contrast enhanced image according to the first group of selected echo signals;
- and
- generates a second group of contrast enhanced image according to the second group of selected echo signals;
- and
- a display device which differently displays the first group of contrast enhanced image and the second group of contrast enhanced image;
- wherein the first number is greater than the second number.
A contrast enhanced ultrasound imaging method, comprising:
- transmitting unfocused waves to the a target region containing microbubbles in multiple angles;
