On ultrasonic diagnostic equipment, adopt touch screen; On the one hand; Realize zoom through the menu area operation of direct or indirect mode (including but not limited to operation such as slide, click, pull) on touch screen with modes such as finger, felt pen, infrared induction, single-point touches, multiple point touching, radio; On the other hand; On image, send message through direct or indirect mode to touch screen, zoom command reception identification module receives this information and sending to message processing module, finally at the image that shows on the display screen after amplifying.As shown in Figure 3, the step that the real-time status hypograph amplifies is following:
Step 1: display image gets into ultrasonic diagnosis;
Step 2: according to doctor's needs, need to judge whether enlarged image, if, execution in step 3, otherwise, execution in step 1;
Step 3: click " ZOOM " icon on the touch screen, ZOOM sampling frame occurs;
Whether the position of step 4:ZOOM sampling frame needs to change, if, execution in step 5, otherwise, execution in step 6;
Step 5: click holds the ZOOM sampling and frames shift moving to desirable position;
Whether the size of step 6:ZOOM sampling frame needs to change, if need to increase the size of ZOOM sampling frame, then execution in step 7, if need reduce the size of ZOOM sampling frame, then execution in step 8;
Step 7: but finger opens outside slip or make it be in after the editing mode to click or to click at new vertex position and hold certain summit to desirable position, executes, and gets into step 9;
Step 8: but finger closes up inside slip or make it be in after the editing mode to click or to click at new vertex position and hold certain summit to desirable position, executes, and gets into step 9;
Step 9: in ZOOM sampling frame zone the optional position click, double-click or long by;
Zoom is to full frame in the step 10:ZOOM sampling frame;
Step 11: the doctor observes this part image and makes diagnosis;
Step 12: judge whether to need to recover primary image, if, execution in step 13, otherwise, execution in step 11;
Step 13: the optional position on touch screen click, double-click or long by, recover original image.
In step 1, at first show ultrasonoscopy on the touch screen, get into ultrasonic diagnosis.In step 2, if the doctor needs certain regional area of primary part observation, then need amplify should the zone, so that the doctor can relatively clearly observe, execution in step 3 then.In step 3, click " ZOOM " icon on the touch screen through direct or indirect mode (including but not limited to) with modes such as infrared ray, felt pen, single-point touches, at this moment a ZOOM sampling frame appears on ultrasonoscopy.In step 4, want the regional area of primary part observation to judge whether needs change for the position of ZOOM sampling frame, if need to change, then execution in step 5 according to the doctor, otherwise, execution in step 6.In step 5, any direction drags the ideal position until the viewing area in the entire image upper edge to click ZOOM sampling frame through direct or indirect mode (including but not limited to modes such as infrared ray, felt pen, single-point touches).In step 6, judge whether the size of ZOOM sampling frame needs to change, if need to increase the size of ZOOM sampling frame, then execution in step 7, if need reduce the size of ZOOM sampling frame, then execution in step 8.In step 7, for the size that increases ZOOM sampling frame, can realize to give an order through sending to touch screen type command reception identification module: one, finger is two refers to simultaneously touch screen and is move toward one another trend slide; After two, but double-click makes it be in editing mode, click at new vertex position; Three, click holds certain summit to desirable position, and the result transmission after this command content of command reception module identification this moment also will be handled shows to display screen, gets into step 9 after being finished.In step 8, for the size that reduces ZOOM sampling frame, can realize to give an order through sending to touch screen type command reception identification module: one, finger is two refers to simultaneously touch screen and is relative motion trend slide; After two, but double-click makes it be in editing mode, click at new vertex position; Three, click holds certain summit to desirable position, and the result transmission after this command content of command reception module identification this moment also will be handled shows to display screen, gets into step 9 after being finished.In step 9, adjust the size and position of ZOOM sampling frame after, the optional position in ZOOM sampling frame is clicked or is double-clicked or longly carries out part amplification by (continuing touch screen a period of time).In step 10, the topography in the ZOOM sampling frame is amplified to full frame.In step 11, the doctor can carry out primary part observation to this area-of-interest, makes diagnosis according to image.In step 12, judge whether that according to doctor's needs needs recover original image, if desired, then execution in step 13, otherwise execution in step 11 continues to do diagnosis.In step 13, need to recover primary diagnostic ultrasound images, click or double-click through direct or indirect mode in any position that is amplified to full frame image or long full frame by just withdrawing from, recover original image.
In the embodiment shown in fig. 3; If the original image display effect does not reach requirement; The doctor can have dual mode to carry out the amplification of topography: a kind of is to regulate through clicking menu on the touch screen, and another kind of convenient mode more is that the doctor directly comes enlarged image through direct or indirect mode (including but not limited to operation such as slide, click, drag with modes such as finger, felt pen, infrared ray, single-point touches, multiple point touching, radio) on image.This dual mode has all solved the vision that keyboard brings and the shortcoming of tactile separation, operates more intuitively.But the second way is more convenient, need not to search corresponding icon and just can realize zoom.
In order more at large to set forth the present invention; In one embodiment of the invention; The change of ZOOM sampling frame size is as shown in Figure 4, and what it provided is to ZOOM sampling frame size adjustment sketch map, because under convex array probe and phased array probe under convex array probe or phased array probe; ZOOM sampling frame all is fan-shaped sampling frame, thus for ZOOM sampling frame amplify or the account form of dwindling identical.In mode shown in Figure 4; Former ZOOM sampling frame ABCD is to serve as the sector region of the fan heart with an O; When the doctor wants ZOOM sampling frame amplified, can double-click ZOOM sampling frame earlier after, in its outside optional position point B1 click or directly drag a B to reposition point B1; Then the command reception module is confirmed new summit C1 according to radian and position, fan heart O and the some B1 connecting line of former sampling frame place circular arc; Calculate the position of an A1 then according to the line segment length between an O and the some B1, D position, former summit does not change, and confirms the size of new sampling frame A1B1C1D at last.If want to reduce to take a sample the frame size, can double-click the sampling frame earlier after, the optional position point B2 of portion clicks or directly drags a B to reposition point B2 within it, confirms the position that new sampling frame A2B2C2D belongs to mode same in the above-mentioned amplifieroperation.
In another embodiment of the present invention; Different with mode shown in Figure 4 is; In mode shown in Figure 5, after confirming new vertex position point B1, not only change the position of three the summit As nearest, some B and some C with new vertex position in the outside optional position of ZOOM sampling frame; Also change some D position, wherein computational methods are identical.This dual mode all is to amplify and the mode of ZOOM sampling frame size variation when dwindling; And when amplifying or dwindle; New ZOOM sampling frame and original ZOOM sampling frame remain the same fan heart; And difference is that mode shown in Figure 4 only changes and the position on three summits that new vertex position is nearest, and as long as mode shown in Figure 5 is after confirming new vertex position, and four summits of then fan-shaped ZOOM sampling frame are all to change the position in proportion.
Equally; Also can adopt aforesaid way that the size of ZOOM sampling frame is regulated for linear array probe; Like Fig. 6 and shown in Figure 7, wherein ZOOM sampling frame size variation mode is with identical under convex array probe or phased array probe, and difference only is that the account form of new ZOOM sampling frame size is different.In mode shown in Figure 6, former ZOOM sampling frame ABCD is to be the rectangular area of axis of symmetry with coordinate axes xy, when as if the doctor ZOOM sampling frame being carried out amplifieroperation; After then can double-clicking ZOOM sampling frame earlier, drag a B to reposition point B1 in its outside optional position point B1 click or through direct or indirect mode, according to the coordinate Calculation magnification ratio of a B1 with some B; Such as a B coordinate be (x, y), some B1 coordinate is (x1; Y1); Then magnification ratio k is x1/x or y1/y, and the command reception module to calculate the position of make new advances summit A1, C1 in proportion, is finally confirmed the size of new ZOOM sampling frame A1B1C1D according to adjacent vertex A, C coordinate then.If will reduce the frame size of taking a sample; Can double-click behind the sampling frame optional position point B2 click of portion within it earlier or drag a B and put B2 to reposition through direct or indirect mode; Mode with same in the above-mentioned amplifieroperation is dwindled, and confirms the position at new ZOOM sampling frame A2B2C2D place.In mode shown in Figure 7, according to the coordinate Calculation magnification ratio of a B1 with some B, adjacent vertex A, some C and some D finally confirm the size of new ZOOM sampling frame A1B1C1D1 to calculate the position of the summit A1 that makes new advances, some C1 and some D1 in proportion then.The difference of this dual mode is that mode shown in Figure 6 only changes the position with nearest three summits of reposition; In each the variation, the axis of symmetry of rectangle ZOOM sampling frame correspondence is changed to x1 or x2 such as horizontal symmetry axis by x also changing; Vertically axis of symmetry is changed to y1 or y2 by y; That is to say that new ZOOM sampling frame and former ZOOM sampling frame are not to amplify in proportion or dwindle with same axis of symmetry, and in mode shown in Figure 7, as long as behind the position on definite new summit; Then four summits of rectangle ZOOM sampling frame are all to change the position in proportion; No matter be to amplify or reduction operation, new ZOOM sampling frame and former ZOOM sampling frame are the axis of symmetry symmetry with original coordinates axle xy all, that is to say that new ZOOM sampling frame and former ZOOM sampling frame carry out size variation in proportion with same axis of symmetry.
