Abstract
The present invention provides an ultrasound system, which comprises: a signal acquiring unit to transmit an ultrasound signal to an object and acquire an echo signal reflected from the object; a signal processing unit to control TGC (Time Gain Compensation) and LGC (Lateral Gain Compensation) of the echo signal; a TGC/LGC setup unit adapted to set TGC and LGC values based on TGC and LGC curves inputted by a user; and an image producing unit adapted to produce an ultrasound image of the object based on the echo signal. The signal processing unit is further adapted to control the TGC and the LGC of the echo signal based on the TGC and LGC values set by the TGC/LGC setup unit.
Claims17
An ultrasound system, comprising:
- a plurality of transducers configured to transmit an ultrasound signal to an object and receive echo signal reflected from the object;
- a beam former configured to focus the transmitted ultrasound signal and collect the echo signal with corresponding time delay;
- and
- a processor configured to:
- display at least one reference line on a touch panel,
- receive a touch input through the touch panel, wherein the touch input intersects with the displayed at least one reference line, and comprises a plurality of touch input points including a first touch input point and a second touch input point,
- determine a first time gain compensation (TGC) value and a second TGC value at two different depths corresponding to the first touch input point and the second touch input point respectively,
- perform compensation on the echo signal based on the determined first TGC value and the second TGC value, and
- generate an ultrasound image of the object based on the compensated echo signal,
- wherein the first touch input point and the second touch input point for setting the first TGC value and the second TGC value are received via a single touch input forming a single curve, and
- wherein the single curve is displayed on the touch panel, and the displayed at least one reference line and the displayed single curve are displayed as different types of lines.
A method of controlling an ultrasound system comprising:
- transmitting an ultrasound signal to an object and receiving echo signal reflected from the object;
- focussing the transmitted ultrasound signal and collecting the echo signal with corresponding time delay;
- displaying at least one reference line;
- receiving a touch input, wherein the touch input intersects with the displayed at least one reference line, and comprises a plurality of touch input points including a first touch input point and a second touch input point;
- determining a first time gain compensation (TGC) value and a second TGC value at two different depths corresponding to the first touch input point and the second touch input point respectively,
- performing compensation on the echo signal based on the determined first TGC value and the second TGC value, and
- generating an ultrasound image of the object based on the compensated echo signal,
- wherein the first touch input point and the second touch input point for setting the first TGC value and the second TGC value are received via a single touch input forming a single curve, and
- wherein the single curve is displayed, and the displayed at least one reference line and the displayed single curve are displayed as different types of lines.
