Provided is an apparatus and method for reconstructing a computed tomography (CT) image using a color channel of a graphic processing unit (GPU) that reconstructs a three-dimensional (3D) image using a projection image obtained from a CT device. According to an embodiment of the present invention, an apparatus for reconstructing a CT image may include a tomography unit to acquire a plurality of projection images, a filter application unit to load the plurality of projection images on a texture memory having a color channel, and filter the plurality of projection images, and a back-projection application unit to apply a back-projection scheme to the plurality of projection images loaded on the texture memory having a color channel.

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.

An apparatus for detecting an examination tissue using an ultrasound signal is disclosed. The apparatus includes a scanning unit to generate an image related to an object, using the ultrasound signal, a sampling unit to convert a resolution of the generated image, and a controlling unit to retrieve an n-number of figure lines from the resolution-converted image and thereby determine whether each of the retrieved figures line is an examination tissue, wherein n is a natural number.

There are provided a method and support device for measuring jawbone mineral density using a jawbone X-ray image. The method for measuring jawbone mineral density includes: obtaining a jawbone X-ray image using a support device for jawbone; defining a region of interest from the obtained jawbone X-ray image; and measuring jawbone mineral density from the defined region of interest. Therefore, the support device for measuring jawbone mineral density may be useful to measure jawbone mineral density with a jawbone X-ray imaging device, which has been widely used in dental clinics, by using the method.

A non-intrusive wearable respiratory failure alarm apparatus and method capable of detecting a user's respiratory failure state by estimating a change in a user's respiratory rate, while minimizing restrictions on a user's behavior are provided. The non-intrusive wearable respiratory failure alarm apparatus includes: a chest girth measurement unit including one or more resistive electro-threads attached to or worn on a user's chest, and generating a resistance value corresponding to the user's chest girth through the resistive electro-threads; a signal processing unit calculating a user's respiratory rate and whether or not the user is in respiratory failure by referring to the resistance value; and an output unit providing information regarding the user's respiratory rate and/or information regarding whether or not the user is in respiratory failure to the user or a monitoring device.
