摘要： Ultrasound diagnostic equipment comprises a tissue power unit for calculating tissue scattering power of tissues of an object of measurement in an organ, a blood power unit for calculating scattering power of blood in the organ and estimating blood scattering power at a portion of the tissues of the object of measurement by using the calculated scattering power of the blood, an integrated backscatter unit for normalizing the tissue scattering power by using the estimated blood scattering power and calculating an integrated backscatter by the normalized tissue scattering power, and a display unit for displaying the integrated backscatter. Therefore, the integrated backscatter of the tissues can be quantitatively estimated without being influenced by attenuation. Furthermore, this estimated quantitative integrated backscatter of the tissues is displayed on the display unit accompanied with a B-mode image, an electrocardiogram, and the like, so that diagnostic accuracy can be increased.

摘要： There is provided an ultrasonic diagnostic system wherein received signals are generated in such a manner that ultrasonic pulse beams are transmitted within a subject and reflecting ultrasonic waves from an inside of the subject are received, and a tomographic image is obtained on the basis of the received signals. The ultrasonic diagnostic system is capable of detecting a velocity or a velocity gradient as to the tissue within the subject. Two digital complex signals [R.sub.i (t)+j I.sub.i (t)] and [R.sub.i (t+.DELTA..tau.)+j I.sub.i (t+.DELTA..tau.)], which are apart from each other by .DELTA..tau., are obtained from a complex signal (quadrature detection signal) [h.sub.ci (t)+j h.sub.si (t)] outputted from a complex signal conversion circuit. A phase difference .DELTA..theta..sub.i,i+1 (t) is determined from a complex correlation value C.sub.i,i (t,.DELTA..tau.) of these two complex signals. Further, the phase difference .DELTA..theta..sub.i,i+1 (t) is determined from a complex correlation value C.sub.i,i+1 (t) of signal-to-signal during repetition of transmission of ultrasonic pulse beams. Using these phase differences, time difference .DELTA. t corresponding to a movement quantity within the subject is calculated on the basis of equation:.DELTA.t=.DELTA..theta..sub.i,i+1 (t).multidot..DELTA..tau./{.DELTA..theta..sub.i,i (t, .DELTA.t)-.omega..sub.o .DELTA..tau.}

摘要： An information processing device having an activation verification function comprises: a module recording portion which stores plural system programs, a security chip having the function of checking the validity of the system programs and a verification portion which inspects the activation states of the system programs. The security chip executes validity checking processing using verification data provided by the system programs. If the security chip cannot confirm the validity of the system programs, the verification portion acquires activation-state information about activated system programs from the activated system programs. If pre-stored verification-information initial values for valid system programs and the acquired activation-state information match with each other, the verification portion determines that the current activation states of the system programs are valid, and the subsequent activation processing for the system programs is advanced.
