Exposure record totalizer and radiography system

Abstract

An exposure record totalizer includes: a hardware processor that adds up a first exposure record of a first exposure image and a second exposure record of a second exposure image, when a radiography system generates the first exposure image through first exposure and the second exposure image through second exposure, and that links information about a third exposure record to a third exposure image generated on the basis of the first exposure image and the second exposure image, the third exposure record being generated by the hardware processor.

         21 . An exposure record storage device comprising:
 a hardware processor that receives a first exposure record which is an actual exposure record of a first exposure and a second exposure record which is an actual exposure record of a second exposure, when a radiography system generates a first exposure image through the first exposure and a second exposure image through the second exposure, the first exposure record including a parameter with a first value, the second exposure record including the parameter with a second value, the parameter being at least one of an irradiation time, a tube current time product, an area dose value and an incident surface dose value;   that generates a third image based on the first exposure image and the second exposure image; and   that links the first exposure record and the second exposure record to the third exposure image.   
     
     
         22 . The exposure record storage device according to  claim 21 , wherein
 the hardware processor generates the third image by combining the first exposure image and the second exposure image.   
     
     
         23 . The exposure record storage device according to  claim 21 , wherein
 when the hardware processor determines not to add up the first exposure record and the second exposure record, the hardware processor links the first exposure record and the second exposure record to the third exposure image.   
     
     
         24 . The exposure record storage device according to  claim 23 , wherein
 when a radiation quality differs between the first exposure and the second exposure, the hardware processor determines not to add up the first exposure record and the second exposure record.   
     
     
         25 . The exposure record storage device according to  claim 23 , wherein
 when an added filter in an irradiator differs between the first exposure and the second exposure, the hardware processor determines not to add up the first exposure record and the second exposure record.   
     
     
         26 . The exposure record storage device according to  claim 21 , wherein
 the hardware processor that displays, on a display, the third exposure image and the second exposure record.   
     
     
         27 . The exposure record storage device according to  claim 21 , wherein
 the hardware processor that displays, on a display, the second exposure image, the third exposure image and the second exposure record.   
     
     
         28 . An exposure record storage method comprising:
 receiving a first exposure record which is an actual exposure record of a first exposure and a second exposure record which is an actual exposure record of a second exposure, when a radiography system generates a first exposure image through the first exposure and a second exposure image through the second exposure, the first exposure record including a parameter with a first value, the second exposure record including the parameter with a second value, the parameter being at least one of an irradiation time, a tube current time product, an area dose value and an incident surface dose value;   generating a third image based on the first exposure image and the second exposure image; and   linking the first exposure record and the second exposure record to the third exposure image.   
     
     
         29 . A radiography system comprising:
 an irradiator that emits radiation;   a radiographic imager that generates image data of an exposure image by receiving the radiation; and   the exposure record storage device according to  claim 21 .
