first embodiment
[0040] First of all, described is the structure of an ultrasonic diagnostic apparatus 100 of a first embodiment by referring to FIG. 2. The ultrasonic diagnostic apparatus 100 of the present embodiment is the one performing TIC / MTT measurement utilizing RF data (data after phase addition) as will be described later.
[0041]FIG. 2 is a block diagram showing the structure of the ultrasonic diagnostic apparatus 100. As shown in FIG. 2, the present ultrasonic diagnostic apparatus 100 is structured by an electrocardiogram (ECG) 1, an ultrasonic probe 4, an apparatus body 22, an operation panel 15, and an input unit 35. In the below, each of those components will be described.
[0042] The electrocardiogram (ECG: ElectroCardioGram) 1 measures a graph having recorded the time-varying electrical phenomena of a subject's heart, i.e., electrocardiogram. Electrocardiogram waveform signals detected by the electrocardiogram 1 are forwarded to reference data memory 3 via an amplifier 2, and if requi...
second embodiment
[0118] In a second embodiment, shown is an ultrasonic diagnostic apparatus 102 for executing a TIC / MTT measurement process based on IQ data (data having been subjected to phase detection by the receiver section 7 but not yet subjected to the process by the B-mode unit 30 or the CFM unit).
[0119]FIG. 11 is a block diagram showing the structure of the ultrasonic diagnostic apparatus 102 of the present embodiment. In FIG. 11, the TIC / MTT measurement section 25 receives the IQ data having been subjected to phase detection from the receiver section 7 to go through the TIC / MTT measurement process. This TIC / MTT measurement process is similar to the first embodiment. As to the effective information extraction process utilizing the IQ data, it is possible to execute that in a similar manner to the first embodiment.
[0120] With such a structure, the effects similar to the first embodiment can be achieved. In the second embodiment, due to high-speed calculation and hardware limitation, the IQ ...
third embodiment
[0121] A third embodiment shows an exemplary TIC / MTT measurement process to be executed based on B-mode detection data (data having been subjected to envelop detection by the envelop detection circuit 30A but not yet subjected to logarithmic transformation by the logarithmic transformation unit 30B).
[0122]FIG. 12 is a block diagram showing the structure of an ultrasonic diagnostic apparatus 104 of the present embodiment. In FIG. 12, the TIC / MTT measurement section 25 receives, from the B-mode unit 30, the B-mode detection data having been subjected to envelop detection by the envelop detection circuit 30A to go through the TIC / MTT measurement process. This TIC / MTT measurement process is similar to the first embodiment. As to the effective information extraction process utilizing the B-mode detection data, it is possible to execute in a similar manner to the first embodiment.
[0123] With such a structure, the effects similar to the first embodiment can be achieved.
