The important information what displays program is the size of file created. We should always choose the compromise among size of file and his quality. For the sensitometer scale scanning we should choose resolution of 300 dpi. 8) Scanning.

Student’s Laboratory, Department of Biophysics VII. Manuals for the XR-100 laboratory X-ray tube and Eclipse II power supply. XR-100 X-ray tube is the laboratory device producing small intensity X-ray radiation. The tube is installed in the upper part of the aluminum box filled with the lead. The vertical position of the tube (its distance from the phantom) may be set with the knob. Phantom is placed in the central opened space. Below, inside the box the intensifying radiographic screen and the CCD camera for registration of the digital images are placed (Fig. VII.1.): Fig. VII.1. Experimental unit for angiographic and radiographic measurements with the power supply. Attention. High voltage power supply Eclipse II (Fig. VII.2.) is very easy for malfunctioning and it is strongly important to applied in details the manuals or asking assistant for help. Operation of the X-Ray tube XR-100 and high voltage power supply Eclipse II: 1. Turning of the X-ray tube power supply ON and OFF should be done under supervising of the assistant. 2. Turn ON the power supply with the Power switch (rear panel). The X-ray tube setting knob Upper aluminum box with internal lead core and X-ray tube XR-100 inside Open space in the experimental unit for placing the investigated object Intensifying screen (inside the bottom box) CCD camera (inside the bottom box) Main power ON/OFF (in the rear panel of the power supply) Power supply Eclipse II 3. Press and hold the button Preset and set the proper parameters U [kV] and I [μA] with knobs E and F respectively (Fig. VII.2.). 4. Emission of the radiation begins after turning the Enable switch ON and lasts up to turning it OFF. Dental Radiography 7
