Embodiment Construction

[0025] The technical solution of the present invention will be specifically described below in conjunction with the accompanying drawings.

[0026] The invention provides a method for measuring and calculating the resection area of ​​a skin tumor, comprising the following steps:

[0027] Step S1: Acquisition of skin tumor images in the skin tumor area to be resected to obtain skin tumor images;

[0028] Step S2: using a computer to extract the tumor contour line of the skin tumor image;

[0029] Step S3: Determine the feature points of the tumor contour line, and obtain a set of feature points;

[0030] Step S4: Establishing graphic geometric information of the tumor contour line;

[0031] Step S5: performing triangulation on the feature point set of the tumor contour line;

[0032] Step S6: Calculate the tumor contour area.

[0033] Further, in this embodiment, in step S1, a skin tumor image of the patient's skin tumor area to be resected is collected through a dermatosco...

Abstract

The invention relates to a skin tumor resection area calculating method. The method comprises the steps that a skin tumor image is collected in the skin tumor region of a tumor to be resected, and theskin tumor image is acquired; the tumor contour line of the skin tumor image is extracted by a computer; feature points of the tumor contour line are determined, and a feature point set is acquired;the graphic geometric information of the tumor contour line is established; the feature point set of the tumor contour line is triangulated; and the tumor contour area is calculated. According to theskin tumor resection area calculating method, image acquisition is less reliable to the influence of exposure, the shooting angle and the like; the reliability is higher; and the tumor resection areais calculated by accumulating the triangle area, which is more accurate.

Description

technical field [0001] The invention relates to the fields of clinical medicine and skin tumors, in particular to a method for measuring and calculating the resection area of ​​skin tumors. Background technique [0002] Surgical resection is an effective means of first-line clinical treatment of skin tumors, and accurate calculation of the resected area of ​​skin tumors can provide a design basis for the formulation of subsequent skin flap surgery plans. [0003] The existing measurement method for measuring the area of ​​skin lesions is a bit of an estimation method, that is, first draw the outline of the skin lesion with a ballpoint pen on a piece of paper, and then redraw the outline with a pen. Use a piece of transparent paper with a cross mark on the aforementioned paper with skin lesion projection, count the number of crosses within the outline range, and multiply the area represented by the unit cross by the number of crosses to obtain the area of ​​the skin lesion. ...
