  • Patent number: 11918531
    Abstract: Provided is a thermotherapy device, which includes a first housing (10), a second housing (20) disposed under the first housing (10), a transfer plate (30), at both sides of which transfer rollers (31) are provided, and a pair of guide rails (40) that is provided to the second housing (20) and on which the respective transfer rollers (31) of the transfer plate (30) are placed. The pair of guide rails (40) are integrally molded when the second housing (20) is injection-molded. Thus, since the guide rails on which the transfer rollers of the transfer plate travel are integrally molded when the second housing is injection-molded, inefficiency caused by mounting separate rails as in the related art is removed, and thereby assemblability, productivity, and economic efficiency of the thermotherapy device can be improved.

  • Patent number: 8655039
    Abstract: The method of segmenting a lesion in an image according to the present invention includes the steps of: obtaining an image of a region of interest from an image of a lesion; adjusting the contrast of the obtained image of the region of interest such that the contrast changes according to the distance from the center of the region of interest; removing noise from the image whose contrast is adjusted; and separating the region of the lesion from the noise-removed image. In the step of adjusting the contrast, the image is adjusted such that the contrast is increased as it goes away from the center of the region of interest, and thus it is possible to segment the lesion while maintaining the original shape of the lesion, thereby reliably segmenting the lesion even in the case where the inside of the lesion is not uniform.
