Abstract: A medical imaging apparatus provided with a position recognition member, capable of achieving a precise position recognition without an additional calibration process and preventing the position recognition errors on account of a long term use of components includes an X-ray generating portion configured to generate X-rays and transmit the X-rays, an X-ray detecting portion configured to detect the X-rays transmitted from the X-ray generating portion, a moving portion provided on at least one of the X-ray generating portion and the X-ray detecting portion to move the at least one of the X-ray generating portion and the X-ray detecting portion, and a position recognition member comprising a bar code portion configured to recognize a position of the at least one of the X-ray generating portion and the X-ray detecting portion, which move along the moving portion, and a bar code reader portion to recognize the bar code portion.

Abstract: A method of forming polysilicon, a thin film transistor (TFT) using the polysilicon, and a method of fabricating the TFT are disclosed. The method of forming the polysilicon comprises: forming an insulating layer on a substrate; forming a first electrode and a second electrode on the insulating layer; forming at least one heater layer on the insulating layer so as to connect the first electrode and the second electrode; forming an amorphous material layer containing silicon on the heater layer(s); forming a through-hole under the heater layer(s) by etching the insulating layer; and crystallizing the amorphous material layer into a polysilicon layer by applying a voltage between the first electrode and the second electrode so as to heat the heater layer(s).
