Abstract
The invention relates to the field of the medical endoscope (gastroscopy and colonoscopy) inspection technology, in particular to accurate measurement of the size of a nidus under an endoscope. An open jaw of measurable biopsy forceps is introduced as a reference substance.The length between the two ends of the open jaw of the biopsy forceps outside a body is measured in advance. The jaw of the biopsy forceps is placed on the same plane as the nidus. The distance from the plane where the jaw of the biopsy forceps is located to a lens of the endoscope is made to be equal to the distance from the plane where the nidus is located to the lens of the endoscope. The pixel value between the two ends of the jaw of the biopsy forceps under the endoscope and the pixel value of the radial line of the nidus are measured through software, and then the physical size of the radial line of the nidus can be calculated.
Description
Technical field
The present invention is applied to the measurement that medical science scope (gastroscope, intestinal mirror) checks focus under technical field, particularly scope (ulcer, swollen thing) size.
Background technology
When the focus that digestive tract occurs (ulcer, swollen thing) size is different also there is significant difference in its biological characteristics.Measuring method for ulcer, swollen thing has software measurement method, ocular estimate now.Software measurement method is to measure with the subsidiary software of scope work station.Because of it, do not consider the convergent-divergent effect of scope to measured object, therefore, its measurement result is inaccurate, insecure.Ocular estimate is that experienced scope doctor determines the size of focus by range estimation, and this subjectivity result is inaccurate especially, and can provide different results for the different people of same focus.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides a kind of method can accurately measure ulcer, swollen thing size under scope.
The technical solution adopted in the present invention is: by introducing measurable biopsy forceps jaw as object of reference, and the length when in advance measuring in vitro biopsy forceps jaw and opening, by the pixel value of biopsy forceps jaw and focus under software measurement scope, can convert and draw the physical size of focus.
Compared with prior art, the invention has the beneficial effects as follows: 1, accurate: biopsy forceps jaw and focus are in same plane, so its convergent-divergent multiple is consistent.When biopsy forceps jaw opens, the physical length of its jaw can be measured in vitro, so the focus size that passing ratio calculates is accurately.2, convenient, save time: the focus that digestive tract occurs need to be carried out biopsy and be come that clear and definite it is good pernicious.This measuring method is in biopsy, only need the jaw of biopsy forceps be opened and be placed in focus same plane when inserting biopsy forceps, adopt an image, remaining surveying work completes by software, it is adopted figure process and only needs 2-3 seconds, affects hardly inspection, the biopsy operation of scope.

Fig. 2 adopts figure.
Fig. 3 opens software, opens the picture of adopting.

The specific embodiment
Below the present invention is further described.
Length when 1, measuring in vitro biopsy forceps jaw and open, in picture, the length of biopsy forceps jaw is 0.6cm.
2, adopt figure the jaw of biopsy forceps is placed in to focus same plane, biopsy forceps jaw, focus (being gastric ulcer in this picture) are equated with the distance of endoscope lens.Like this, biopsy forceps jaw and focus will have identical convergent-divergent multiple.
3, open by the software of writing in person (software download address is drjcjjlq@163.com password drjcjjlq1+1 or zlsq2012@126.com password zlsqyx123).Picture buttons is opened in click, opens and is kept at the local picture of adopting.
4, measure the pixel value between biopsy forceps jaw.The left button of clicking the mouse in one end of biopsy forceps jaw, pinning left mouse button does not put, drag mouse to the other end of biopsy forceps jaw and decontrol left mouse button, between biopsy forceps jaw two ends, just there will be line always, the value that will demonstrate in the text box in the software upper left corner between jaw two ends is 106.5, and after it, unit is pixel.
5, carry out self-defined assignment.The self-defined measurement button of clicking below will eject assignment text box above the button that quits a program, and at this moment the upper left resulting text frame of software unit below will change into centimetre automatically.Corresponding, in first text box, input 0.6(and note: the unit of input numerical value for centimetre), in second text box, input 106.5, (its unit is pixel).Object of this step operation is exactly to tell software 106.5 pixels in this picture to be equivalent to the length of 0.6cm.
[0012] 6, measure the size of the long and short diameter of ulcer.Click the mouse in one end of ulcer major diameter left button press and drag mouse to the major diameter other end and unclamp mouse just there will be line always between the two ends of ulcer major diameter.At this moment 1.3 centimetres of the text box in the software upper left corner shows numerical value are exactly the size of ulcer major diameter.The length that same method can be measured ulcer minor axis is 1cm.
Claims (1)
1. an accurate measurement method for focus size under scope, by introducing the biopsy forceps of measurement size opens in vitro jaw as object of reference, goes out focus and biopsy forceps opens the length in pixels of jaw with software measurement, thereby calculates the size of focus.
