Radiographic image acquiring device, radiographic image acquiring system, and radiographic image acquisition method

A radiographic image acquiring device comprising:

• an imaging device configured to scan radiation passing through a target object in one direction and capture an image thereof to acquire a radiographic image;
• a scintillator configured to be provided on the imaging device to convert the radiation into light;
• and
• an image processing module configured to calculate an average energy related to the radiation passing through the target object, evaluate the spread of a noise value using the average energy, input the radiographic image to a trained model constructed through machine training in advance using image data and execute a noise removal process of removing noise from the radiographic image,
• wherein the imaging device includes
• a detection element in which pixel lines each having M (M is an integer equal to or greater than 2) pixels arranged in the one direction are configured to be arranged in N columns (N is an integer equal to or greater than 2) in a direction orthogonal to the one direction and which is configured to output a detection signal related to the light for each of the pixels, and
• a readout circuit configured to output the radiographic image by adding the detection signals output from at least two of the M pixels for each of the pixel lines of N columns in the detection element and sequentially outputting the added N detection signals, and
• wherein the image processing module includes
• at least one processor configured to derive an evaluation value obtained by evaluating a spread of a noise value from a pixel value of each pixel of the radiographic image on the basis of relational data indicating a relationship between the pixel value and the evaluation value and generate a noise map which is data obtained by associating the derived evaluation value with each pixel of the radiographic image, and
• input the radiographic image and the noise map to the trained model and execute the noise removal process of removing noise from the radiographic image.
