Abstract
In medical image recording apparatus, exposure section forms a latent image on film by exposing film based on a testing exposure signal for correction of density characteristics of the leading edge and/or the trailing edge of film, and heat development section heat-develops to visualize the latent image and records it on film, and density measurement section measures the density characteristics of the testing exposure signal on the heat-developed film and then, shading correction section determines the correction areas of the leading edge and/or the trailing edge of film based on the result of the density measurement and corrects the density characteristics of the leading edge and/or the trailing edge of film for the correction areas at the image recording stage of a diagnostic image data.
Claims3
An image recording apparatus comprising:
- a film retaining device which can retain at least one size of a sheet film among a plurality of sizes of sheet films which are formed by coating an emulsion including a photosensitive and a heat-sensitive recording material on a support material;
- an exposure section for forming a latent image by applying scanning exposure on the film according to image data for output;
- a heat development section for visualizing the latent image on the film by heating the film exposed by the exposure section;
- and
- a shading correction section for carrying out density correction of the image data for output such that a density level of the visualized image on the film is even on an entire surface of the film,
- wherein the shading correction section carries out the density correction corresponding to each size of the films.
