摘要:
An image forming method and its apparatus are disclosed. The method comprises exposing a light-sensitive silver halide photographic material having a support and hydrophilic colloid layers provided on both sides of the support and developing the exposed material with a developing solution without immersing it in the developing solution. The apparatus comprises (a) a pair of rollers for transporting the material in a downward direction and (b) a pair of nozzles for feeding the developing solution to both sides of the material, the nozzles being provided above the rollers.
摘要:
An X-ray radiography system comprising divided fan beam scanning device, feed-back the beam regulator and a silver halide photosensitive material having a covering power not less than 45 which is capable to diagnose wide range of photo-density area at one time exposure for minimizing the radiation dose is disclosed.
摘要:
Disclosed is a light-sensitive silver halide photographic material for X-ray photography, characterized in that the material has the characteristic curve whose gamma between optical densities of 0.50 and 1.50 is 2.7 to 3.3 and gamma between optical densities of 2.00 and 3.00 is 1.5 to 2.5, when processed by use of a prescribed developer.
摘要:
A silver halide light-sensitive photographic material suitable for radiographic use is described having a transparent support provided with a silver halide emulsion layer on both sides thereof, intended to be subjected to exposure to X-rays in combination with a fluorescent or phosphorescent substance which is rendered luminous by the action of X-ray irradiation, characterised in that the value obtained by subtracting the blue light transmission density of said transparent support from the blue light transmission density of said light-sensitive photographic material is not more than 0.60.
摘要:
A silver halide photographic material is disclosed which comprises a support and a hydrophilic colloidal layer thereon containing a low molecular weight polymer having acrylic acid and/or methacrylic acid units or a salt thereof.
