Automatic Image guided tissue removal and processing

Multi-dimensional imaging system for endoscope

An image acquisition system employs elemental and/or lateral effect detectors in conjunction with an optical scanner which provides a beam of radiation tracing out a raster to illuminate an object. The system generates an electrical signal which is processed to generate data indicative of a two or three dimensional image of an object, in spectrally selective monochromatic wavelengths or broadband regions. An endoscope is designed to make particular use of this image generating system. The image system includes a digital system able to provide a data matrix of two and three dimensional coordinates and the radiation intensity at each of the coordinates as well as spectral dependent image processing, display and archival storage.

A medical improving skin wrinkles using a laser RRSS of Laser beam irradiator and method

The present invention relates to a medical skin wrinkle improving device using an RRSS irradiating method of a laser, which is capable of improving skin wrinkles and minimizing tissue damage. The medical skin wrinkle improving device comprises a main body, a handpiece, and a tablet computer. The main body includes: a mounting groove, from which the tablet computer is detached, in an upper part; a signal transmitting and receiving unit which is connected to the tablet computer and transmits and receives signals; and a MICOM which controls laser output. The handpiece includes: a laser oscillating unit which generates the laser irradiated for skin treatment; an optical unit which irradiates the laser generated in the laser oscillating unit with balanced light; a laser scanner which controls irradiating positions of the laser received in the optical unit; and a laser pattern unit in which a movement coordinate value is set so that a moving direction of the laser, which is transmitted in a surgery area outer boundary line called through a surgery area display, is performed in a regular pattern type. The tablet computer includes functions of data input and screen display by a touch screen method and remotely controls the main body through transmitting and receiving of bidirectional signals. The MICOM reduces PIH and D.T. by securing cooling time for a position to which a laser beam is transmitted in a skin surgery step of irradiating the laser beam to skins through time & maximum space cooling by using a peak value of a laser pulse when an amplitude of the generated laser pulse reaches a peak value and then reaches a predetermined normal state value. The MICOM prevents a local burn by not repeatedly irradiating the laser beam to a specific position.

A medical improving skin wrinkles using a laser pulse peak

The present invention relates to a medical skin wrinkle alleviating apparatus using a peak value of laser pulse waves.

Method and systems for generating images in coherent radiation and controlling with feedback for modifying materials

Изобретение относится к способам и системам для формирования изображений в когерентном излучении и управления с обратной связью для модификации материалов и может быть использовано в процессах модификации материалов, таких как лазерная хирургия, спекание и сварка. Источник пучка для обработки материала выдает пучок для обработки материала, который подается в место расположения материала в процессе модификации материала. Оптический источник для формирования изображений выдает световое излучение для формирования изображения. Оптический интерферометр выдает выходной сигнал интерферометрии с использованием по меньшей мере компонента светового излучения для формирования изображения, которое поступает к образцу. Входной сигнал интерферометрии основывается на сравнении по меньшей мере одной длины оптического пути к образцу и другой длины оптического пути. Контроллер с обратной связью управляет по меньшей мере одним параметром обработки процесса модификации материала на основании выходного сигнала интерферометрии. Процесс модификации материала выбирают из спекания, сварки и пайки или их сочетания.
