However, when using ultraviolet light for irradiation at present, hospitals often only provide several masks with fixed sizes
In order to prevent the surrounding normal tissues from being burned by ultraviolet rays, the doctor can only choose a mask with the closest size from several fixed-sized masks, and the vitiligo area can be completely irradiated by multiple shifts and superimposed irradiation. It also often leads to the uneven irradiation dose received by the vitiligo lesion area during the phototherapy process, which not only fails to achieve a better treatment effect for vitiligo, but also easily causes toxic and side effects, causing secondary damage
In addition, this fixed-size mask is continuously reused during the treatment of different patients. If the disinfection is not thorough, there will be a safety hazard of infection

Embodiment Construction
[0012] The utility model will be further explained below in conjunction with the accompanying drawings and specific embodiments.
[0013] The invention provides a method for preparing a personalized mask for ultraviolet phototherapy of vitiligo, which comprises the following steps:
[0014] Step S1: Provide an image acquisition module, through which the image of the vitiligo onset area is obtained, and imported into the host computer for image processing and three-dimensional reconstruction; figure 1 shown;
[0015] Step S2: Since the image is easily affected by noise during the process of acquisition and transmission, in order to improve the accuracy of automatic image segmentation, the host computer first preprocesses the image to remove noise to improve the quality of the image;
[0016] Step S3: smoothing the rough part in the image by smoothing technology;
[0017] Step S4: Using the adaptive threshold segmentation method to automatically segment the vitiligo lesion are...

The invention discloses a preparation method of a customized mask for leucoderma UV phototherapy. According to the actual shape and the size of a leucoderma lesion area, through combination of image segmentation, three-dimensional reconstruction and 3D printing technologies, a UV phototherapy mask matching the leucoderma lesion area is made. When the UV phototherapy is implemented, the customized mask can accurately and completely cover a region of disease, uniformly concentrates an irradiation dosage at a lesion position to the utmost extent, while ensuring that a lesion can obtain a sufficient irradiation dosage, also prevents normal skin around from unnecessary UV irradiation, reduces toxic side effects of the UV phototherapy, improves the treatment effect and is convenient and feasible.
Description
technical field [0001] The invention relates to medical equipment, in particular to a method for preparing a personalized mask for ultraviolet phototherapy of vitiligo. Background technique [0002] Vitiligo is a common and refractory depigmentation skin disease. Its etiology and pathogenesis are not yet clear. One of the three major chronic diseases of skin diseases, there is no obvious gender difference, and it can occur in all age groups, but it is more common in young people. Although vitiligo does not cause organ damage, it may seriously affect the physical and mental health of patients. Effective treatment can not only improve the physiological functions of patients, but also improve the quality of life and physical and mental health of patients. [0003] Since the pathogenesis of vitiligo is still unclear, its treatment has always been a medical problem. Although there are many treatment methods at present, the curative effect is not satisfactory. For example, the a...
