Abstract
Provided are an ultrasound diagnosis apparatus and method of operating the same. The ultrasound diagnosis apparatus includes: a data acquisition unit configured to acquire flow data in real-time from a region of interest (ROI) of an object; a parameter setting unit configured to analyze a change in blood flow based on the flow data acquired in real-time and set a parameter according to the analyzed change in blood flow; an image generator configured to generate a color flow image of the ROI by applying the set parameter to the flow data; and a display configured to display the color flow image.
Claims11
An ultrasound diagnosis apparatus comprising:
- an ultrasound probe configured to acquire flow data in real-time from a region of interest (ROI) of an object, the object comprising an organ, a blood vessel, or a combination thereof, or a phantom;
- a Doppler processor configured to analyze power data of blood flow by using the flow data, generate a histogram of the power data of blood flow in real-time indicating a frequency of occurrence for each power value, set a power threshold according to a change in an amount of the blood flow by analyzing the histogram, determine power values that are less than the power threshold as noise, and determine power values that are greater than or equal to the power threshold as effective signals, wherein the power threshold is a parameter for determining a lower limit for the power data;
- an image processor configured to generate a color flow image of the ROI by using the effective signals, excluding the noise;
- and
- a display configured to display the color flow image,
- wherein the Doppler processor is further configured to adjust the power threshold to increase in real-time as an amount of blood flow through the ROI increases in real-time and to decrease in real-time as the amount of the blood flow through the ROI decreases in real-time.
A method of operating an ultrasound diagnosis apparatus, the method comprising:
- acquiring flow data in real-time from a region of interest (ROI) of an object, the object comprising an organ, a blood vessel, or a combination thereof, or a phantom;
- analyzing power data of blood flow by using the flow data acquired in real-time;
- generating a histogram of the power data of blood flow in real-time indicating a frequency of occurrence for each power value;
- setting a power threshold according to a change in an amount of the blood flow by analyzing the histogram, wherein the power threshold is a parameter for determining a lower limit for the power data;
- determining power values that are less than the power threshold as noise, and determining power values that are greater than or equal to the power threshold as effective signals;
- generating a color flow image of the ROI by using the effective signals, excluding the noise;
- and
- displaying the color flow image,
- wherein, in the setting of the power threshold, the power threshold is adjusted to increase in real-time as an amount of blood flow through the ROI increases in real-time and to decrease in real-time as the amount of the blood flow through the ROI decreases in real-time.
