Embodiment approach 1
[0046] figure 1 It is a block diagram showing the configuration of an ultrasound diagnostic system including the ultrasound observation device according to Embodiment 1 of the present invention. Such as figure 1 As shown, the ultrasonic diagnostic system 1 includes: an ultrasonic endoscope 2, which transmits ultrasonic waves to an object to be observed and receives ultrasonic waves reflected by the object; 2 to generate an ultrasonic image from the acquired ultrasonic signal; a display device 4, which is used to display the ultrasonic image generated by the ultrasonic observation device 3; and an input device 5, which is used to accept the setting of the observation mode performed by the ultrasonic observation device 3 , Setting of observation conditions, etc. Instruction signal input.
[0047] figure 2 is showing figure 1 A diagram showing the structure of the input device. image 3 It is a diagram showing a situation where an ROI is set below an ultrasonic image. I...
Deformed example 1-1
[0096] In Embodiment 1, the amount by which the ROI is reduced or enlarged according to the pinch-in operation or the pinch-out operation may be changed according to the correlation (|α-β|). Figure 14 It is a diagram for explaining the operation of the ultrasonic observation device according to Modification 1-1 of Embodiment 1 of the present invention. Such as Figure 14 As shown, it may also be that the direction of the kneading operation is along the direction of the straight line l21 and the kneading operation satisfying 0°≤|α-β|≤45° or 135°≤|α-β|<180° is performed In this case, cos(|α-β|) is multiplied by the movement amount of the pinch-in finger as a coefficient of the amount to shrink the ROI.
[0097] Likewise, when the direction of the kneading operation is a direction along the straight line 122 and a kneading operation that does not satisfy 0°≤|α-β|≤45° or 135°≤|α-β|<180° is performed, sin(|α-β|) may be multiplied by the movement amount of the pinch-in finger as ...
Embodiment approach 2
[0100] Next, an ultrasonic diagnostic system according to Embodiment 2 will be described. The structure of the ultrasonic diagnostic system can be compared with figure 1 The ultrasonic diagnostic system 1 according to Embodiment 1 shown is the same, and therefore description thereof will be appropriately omitted.
[0101] However, in the ultrasonic diagnostic system 1, the operation control unit 34 reduces or reduces the shape of the ROI in two directions, the direction along the reference axis and the direction perpendicular to the reference axis, based on the correlation (|α-β|). enlarge.
[0102] Figure 15 It is a flowchart showing the operation of the ultrasonic observation device according to Embodiment 2 of the present invention. Such as Figure 15 As shown, after performing the same processing as in the first embodiment up to step S7, the control unit 35 causes the operation control unit 34 to map the shape of the ROI in the direction along the reference axis and ...
