Instruction only first is adjusted with touch screen input module receives in the position of current adjustment the first measurement point and the second measurement point, second adjusts positional information and the first measurement point comprising in instruction, the initial coordinate of the second measurement point is relevant, and with the first adjustment instruction, the track that the second adjustment instruction produces on touch screen is without any association, be user can be on touch screen except current region in can the measurement point of editing mode is with any track slide the coordinates correlation connection that makes to adjust the positional information that comprises in instruction and measurement point and then the position of controlling this measurement point.
For adjusting the positional information comprising in instruction, irrelevant with the concrete sliding trace producing during slip.
Finally according to above-mentioned steps, adjust successively the position of the first measurement point and the second measurement point until it all reaches after ideal position, at this moment touch screen input module receives from the arbitrary region beyond all measurement points on touch screen and sends definiteness order really, and will determine that command is to controller, controller receives to be determined instruction and thinks to determine operation; When controller is thought that above-mentioned definite instruction determine operation, the second measurement point is set as determining state, (can not edit adjustment to the second measurement point after adjusting) simultaneously.
Usually, after the second measurement point is adjusted to the right place according to the second adjustment instruction, while also needing the first measurement point again to adjust, only need on touch screen, again input and adjust switching command; Touch screen input module is transferred to controller by adjustment switching command, and controller can be set as the first measurement point again can editing mode, thereby can again to the first measurement point after adjusting, carry out position adjustment; The method that the first measurement point after adjusting is adjusted is again identical with method of adjustment before, no longer describes in detail herein.Meanwhile, then carry out still can between the first measurement point and the second measurement point, repeatedly repeatedly adjusting switching after above-mentioned adjustment, until controller receives definite instruction.
When receiving, controller determines after instruction, controller can will determine that definite information transmission that instruction comprise is in measurement module, by the computing module in measurement module according to the positional distance computing formula computation and measurement result of current the first measurement point and the second measurement point:
The distance after being adjusted between the first measurement point and the second measurement point, as shown in Figure 4, controller receives and identifies the range information output order being transmitted by computing module, and then is transferred to the range information that display screen shows calculating.
Various checking modes based on touch screen diasonograph in conjunction with above-described embodiment, B pattern (B-Mode), M pattern (M-Mode), CFM pattern (colorful blood pattern) and the PW pattern (pulse Doppler pattern) in ultrasonic diagnosis of the localization method of two measurement points in above-mentioned measurement can being applied to is equidistant, time, speed and heart rate measurement etc.
What Fig. 2, Fig. 3 and Fig. 4 described is only the schematic diagram of two measurement point location, but disclosed technical scheme is not limited only to this, further, can also comprise the 3rd measurement point and the 4th measurement point.
In one embodiment of the invention, with ellipse, be measured as example, as shown in Figure 5, first two end points of transverse be designated as to the first measurement point a and the second measurement point b, two end points of ellipse short shaft are designated as the 3rd measurement point c and the 4th measurement point d.
First, by touch screen input module, receiving touch screen measures after instruction, enter oval measuring state, the position that controller receives the instruction sent by touch screen input module the first measurement point is set to current touch screen position and in can editing mode, put as shown in Figure 5 a, coordinate is designated as (x
a, y
a), the position of its excess-three measurement point is preset by system, the second measurement point b, the 3rd measurement point c and the 4th d as shown in Figure 5, and coordinate is designated as respectively b (x
b, y
b), c (x
c, y
c), d (x
d, y
d).In Fig. 5, between the first measurement point a, the second measurement point b, the 3rd measurement point c and the 4th measurement point d, the corresponding track connecting can form oval curve.
Then, touch screen input module receives doctor and to the first measurement point a on touch screen, sends the first adjustment instruction with directional information and positional information by direct or indirect mode, and by the first adjustment command to controller, controller receives first and adjusts instruction and identify the primary importance adjustment information comprising in instruction, and described primary importance adjustment information comprises the terminal point coordinate that the starting point coordinate contacting with touch screen while sliding beginning contacts with touch screen while finishing with slip.Controller is transferred to measurement module by above-mentioned primary importance adjustment information, by the measurement point locating module in measurement module, by starting point coordinate and the terminal point coordinate contacting with touch screen, calculate respectively lateral coordinates side-play amount and along slope coordinate side-play amount, then, and the initial position of the first measurement point a is associated with the positional information comprising in primary importance adjustment information, for example, the primary importance adjustment information comprising in the first adjustment instruction calculates lateral coordinates skew for negative p unit, along slope coordinate skew is negative q unit, the first measurement point a
1coordinate is (x
a-p, y
aand then adjust the first measurement point a to reposition, some a as shown in Figure 6-q),
1.
Then, touch screen input module receives after the adjustment switching command from touch screen, and adjustment switching command is transferred to controller, controller can editing mode according to adjusting that switching command is set as the second measurement point, and the second measurement point is set as to editable pictorial symbolization by display screen, shows output;
When receiving from second of touch screen, touch screen input module adjusts instruction, and by the second adjustment command in controller time, when controller receives and identifies the second position adjustment information comprising in the second adjustment instruction, second position adjustment information is transferred to measurement module, measurement point locating module in measurement module further calculates the position of the second measurement point b, some b as shown in Figure 6
1, controller shows output by the position of the second measurement point b after adjusting by display screen, and then definite major axis position.Then need further by determining the position of the 3rd measurement point c and the 4th measurement point d and then definite minor axis.
Consider oval geometrical symmetry, the in the situation that of known transverse and elliptical center position, the position of oval the 3rd measurement point c and the 4th measurement point d can be simultaneously in can editing mode and and adjust the positional information comprising in instruction and be associated, by once having adjusted, as shown in Figure 6; The process that the 3rd measurement point c and the 4th measurement point d adjust and the adjustment process of the first measurement point a, the second measurement point b are in full accord, are no longer elaborated herein.When the 3rd measurement point c and the 4th measurement point d are when once having adjusted, it is zero that the position adjustment information comprising in instruction is adjusted in the 3rd adjustment instruction or the 4th, so that the adjustment process of the 3rd measurement point c and the 4th measurement point d and required adjustment process are consistent.Terminal when the length variations trend of shown minor axis only finishes with slip on display screen is associated to the vertical dimension of major axis, irrelevant with concrete sliding trace.When above-mentioned the first measurement point a, the second measurement point b, the 3rd measurement point c and the 4th measurement point d carry out after the adjustment of relevant position, if while also needing again to adjust, only need to adjust switching command to input in touch screen input module, be switched to after corresponding measurement point, the position adjustment information comprising by corresponding adjustment instruction and adjustment instruction is adjusted again to measurement point position, whole adjustment process, with adjustment process is consistent before, no longer describes in detail.
Finally, when the position of above-mentioned four measuring point all reaches after ideal position, discharge and adjust instruction, touch screen input module receives from the arbitrary region beyond four measuring point on touch screen and sends definiteness order really, controller receives determines instruction, think to determine operation, and record current four measuring point a simultaneously

d ', y
d '), as shown in Figure 7.
Controller by above-mentioned definite command to measurement module, by computing module wherein calculate oval major semiaxis A and semi-minor axis B as follows:
Thereby calculate, oval girth dough-making powder is long-pending to be respectively:
L＝2·π·B+4·(A-B)；
S＝π·A·B
Wherein, L represents the girth of oval curve, and S represents the area of oval curve.
Further, to the locate mode of measurement point position, can also realize by directionkeys, as shown in Figure 8.Usually, controller by corresponding measurement point be set as can editing mode after, in the surrounding of measurement point, directionkeys is set, described directionkeys comprises upper and lower, left and right four direction.In the situation that measurement point has directionkeys to indicate, can send touch screen instruction to the directionkeys of measurement point.For example, pinning the edge, region at the first measurement point place moves until unclamp after ideal position optional position up and down, controller receives adjusts instruction, record the coordinate of reposition and be transferred to measurement module, by measurement module, calculated to adjust the reposition of rear measurement point and be transferred to controller and then be transferred to display and show, then adjust successively the position of all the other measurement points, finally when the position of all measurement points all reaches after ideal position, touch screen input module receives the instruction sending from the arbitrary region except all measurement points on touch screen, controller receives this instruction, think to determine operation, and by above-mentioned command to measurement module, by computing module wherein according to the position calculation measurement result of current all measurement points, finally, computing module is transferred to controller by result of calculation and then is transferred to display screen and shows.Described measurement point region refers to command reception that aforesaid operations is corresponding and the regional extent of response, and it can be preset the size in this region by system, and there is no particular restriction.
The above-mentioned method that realizes measurement point location by directionkeys can be applied to the situation of a plurality of measurement points, such as ellipse is measured.Although but come location survey point can repeatedly adjust the position of measurement point until be satisfied with before one-shot measurement finishes by said method, but still there is following problem: because finger or the object such as felt pen can cover current mobile measurement point in contact touch screen, make the position of accurate location survey point become more difficult, so, may there is a little drawback in the specific implementation.
Further, on the basis of the technical scheme of the measurement point location of disclosing in the invention described above, for more clearly represent measurement point in whole image residing position so that location, horizontal line and the vertical line of current measurement point position can also be determined according to the abscissa of current measurement point and vertical coordinate, as shown in Figure 9.
In specific implementation process, user can select to show according to the needs of concrete measure the item horizontal line and the vertical line of whole measurement points position, or only in display measurement point place horizontal line or vertical line or all demonstration, such as Measuring Time under M pattern, the calculating of time is that the difference by the lateral coordinates of two measurement points obtains, can select the only vertical line at display measurement point place, as shown in figure 10.
For example, in controller, recording current the first measurement point a coordinate is (m, n), the first measurement point a place linear equation x
