ULTRASOUND DIAGNOSTIC DEVICE, ULTRASOUND DIAGNOSTIC METHOD AND ULTRASOUND DIAGNOSTIC PROGRAM STORAGE MEDIUM |
摘要 |
An ultrasound diagnostic device includes an ultrasound probe including ultrasound transducers that transmit ultrasound toward an imaging subject, receive ultrasound reflected from the imaging subject, and output ultrasound detection signals; an alteration unit that alters a transmission frequency of the transmitted ultrasound or a reception frequency of the received ultrasound, from a frequency for converting amplitudes, of the ultrasound detection signals outputted from the ultrasound probe, into an intensity distribution of brightnesses and displaying the distribution, to a frequency for carrying out diagnosis of tissue characteristics; and a calculation unit that calculates an index for diagnosing tissue characteristics, based on a relationship between received signals, at a time when the transmission frequency or the reception frequency is altered to a frequency at which diagnosis of tissue characteristics is carried out, at two or more different ultrasound transducers at the ultrasound probe. |

1. An ultrasound diagnostic device comprising:
an ultrasound probe including a plurality of ultrasound transducers that transmit ultrasound toward an imaging subject, receive ultrasound reflected from the imaging subject, and output ultrasound detection signals; an alteration unit that alters a transmission frequency of the ultrasound transmitted from the ultrasound probe or a reception frequency of the ultrasound received by the ultrasound probe, from a frequency for converting amplitudes, of the ultrasound detection signals outputted from the ultrasound probe, into an intensity distribution of brightnesses and displaying the distribution, to a frequency for carrying out diagnosis of tissue characteristics; and a calculation unit that calculates an index for diagnosing tissue characteristics, based on a relationship between received signals, at a time when the transmission frequency or the reception frequency is altered by the alteration unit to a frequency at which diagnosis of tissue characteristics is carried out, at two or more different ultrasound transducers at the ultrasound probe. |
