摘要： There is provided a method of processing an ultrasound spectrum image. According to such method, a spectrum image is formed based on ultrasound data and then the noise is removed from the spectrum image. The noise-removed spectrum image is matched with one or more spectrum models representing specific spectrum types. Then, whether or not the noise-removed spectrum image contains an aliasing is checked. If the noise-removed spectrum image contains the aliasing, then the aliasing is removed from the noise-removed spectrum image to provide a noise-removed spectrum image without the aliasing. Thereafter, contour tracing is performed on the noise-removed spectrum image without the aliasing to detect contour points. Further, peak tracing is performed on the noise-removed spectrum image without the aliasing to detect peaks.

摘要： Embodiments for detecting extravasation in an ultrasound system are disclosed. The ultrasound system includes a Tx/Rx unit to transmit an ultrasound beam to a target object and receive ultrasound echoes reflected from the target object to thereby output receive signals. The receive signals include first receive signals obtained before injecting a fluid into the target object and second receive signals obtained after injecting the fluid into the target object. The ultrasound system further includes a processing unit to form a first ultrasound image based on the first receive signals and a second ultrasound image based on the second receive signal. The processing unit further compares the first ultrasound image and the second ultrasound image for detecting extravasation at the target object.
