1. A radiological image processing device that designates a region in a radiological image including a distal portion of a human body, comprising:
- a memory configured to store instructions; and
a processor configured to execute the stored instructions, which when executed by the processor cause the processor to;
extract a partial region which includes the distal portion and has a predetermined range from a boundary between a subject region and a void region from the radiological image; and
determine at least one of the void region or the region including both the void region and the partial region as a designation region for designating the partial region,calculate a feature amount which is a concentration of the radiological image based on the partial region when the designation region is designated;
calculate a target concentration which is converted from the feature amount by determining a thickness of the subject region, andperform image processing such that the calculated feature amount is the calculated target concentration,wherein, when the designation region is designated on the radiological image being displayed, the partial region is designated.

Abstract
A partial region extraction unit extracts a partial region including a distal portion in the vicinity of a boundary between a subject region including the distal portion and a void region from a radiological image including the distal portion of the human body. A designation region determination unit determines at least one of the void region and the partial region as a designation region for designating the partial region.

7. A radiological image processing method in which a region in a radiological image including a distal portion of a human body is designated, the method comprising:
-
extracting, by a processor, a partial region which includes the distal portion and has a predetermined range from a boundary between a subject region and a void region from the radiological image; determining, by the processor, at least one of the void region or the region including both the void region and the partial region as a designation region for designating the partial region; calculating, by the processor, a feature amount which is a concentration of the radiological image based on the partial region when the designation region is designated; calculating, by the processor, a target concentration which is converted from the feature amount by determining a thickness of the subject region, and performing, by the processor, image processing such that the calculated feature amount is the calculated target concentration, wherein, when the designation region is designated on the displayed radiological image, the partial image is designated. - View Dependent Claims (8)

9. A non-transitory recording medium having a program recorded therein that causes a computer to execute a radiological image processing comprising image region designation method that designates a region in a radiological image including a distal portion of a human body recorded therein, the program comprising the procedures of:
-
extracting a partial region which includes the distal portion and has a predetermined range from a boundary between a subject region and a void region from the radiological image; determining at least one of the void region or the region including both the void region and the partial region as a designation region for designating the partial region; calculating a feature amount which is a concentration of the radiological image based on the partial region when the designation region is designated; calculating a target concentration which is converted from the feature amount by determining a thickness of the subject region, and perform image processing such that the calculated feature amount is the calculated target concentration, wherein, when the designation region is designated on the displayed radiological image, the partial region is designated. - View Dependent Claims (10)
