Abstract:
In an ultrasound imaging system generating color flow signals in response to ultrasound signals backscattered from a subject under study and generating image signals based on the amplitude of ultrasound signals backscattered from the subject under study, improved apparatus for displaying images in response to the color flow signals comprising in combination:a terminal connected to receive a threshold signal;a memory connected to store a first set of data words in response to the color flow signals and second set of data words in response to the image signals;a logic unit connected to determine a characteristic value corresponding to at least one characteristic of the second set of data words, to alter the threshold value in response to the characteristic value and to select data words from the first and second sets depending on a predetermined relationship between the altered threshold value and the values of the data words in the first and second sets; anda display connected to display a color flow image in response to the selected data words.
