An imaging position correction application introduction support system is provided with a storage unit and a display unit. The imaging position correction application introduction support system is configured to cause the storage unit to store at least one of the number of times the imaging position correction application was used and a degree of correction when the relative position of the X-ray irradiation unit with respect to the specific site of the subject was corrected by the imaging position correction application, as the tentative use information on when the imaging position correction application is tentatively used. The display unit displays the information based on the tentative use information.

A center of gravity of a chest front image is obtained by a center of gravity calculation using pixel values in the chest front image, and a vicinity pixel position of the center of gravity is set as a center position P of a circular search region having a radius of a predetermined length. The shortest line segment of four line segments obtained by drawing perpendicular lines down from the center position P of an irradiation field to boundary lines of the upper, lower, left and right irradiation fields. The line segment, which is a radius of the circular search region, is rotationally displaced for each predetermined angle &#x3b8;, and the profile of the average value for each predetermined angle &#x3b8; is obtained. From the displacement angle &#x3b8; of the line segment in which the average value becomes minimum, the orientation of the subject from the head to the abdomen reflected in the chest front image is determined. On the other hand, the displacement angle &#x3b8; of the two line segments (diameter line segment) in which the sum of the average values of the two line segments (diameter line segments) opposed at 180&#xb0; in the profile of the average value is obtained as an inclination angle of the chest front image.

Provided is an image processing apparatus capable of assuredly finding a lung field that appears in an image even if a subject image appears in a radiation image in a rotated manner and assuredly performing a contrast adjustment with excellent visibility for the lung field. The image processing apparatus is provided with a sideways determination meansconfigured to determine that the subject image is turned sideways in the original image Pwhen a minimum point P of a profile generated by summing or averaging pixel values belonging to each pixel column of the original image Pfor each pixel column is away from the center position of the subject image. The original image Pdetermined as being turned sideways by the sideways determination portionis rotated by the image rotation portionand used for searching of the lung field.

Image processing apparatus, program, and radiation imaging apparatus

According to the present invention, a total value profile to be used for searching a lung field end is generated based on a radiation image. A pacemaker and an annotation reflected in a radiation image are merely reflected darkly in the image, and the existence is not particularly emphasized by edge enhancement. Therefore, the total value profile according to the present invention is not significantly affected by a pacemaker and/or an annotation. Therefore, according to the present invention, there occurs no false recognition regarding the end of the lung field due to a pacemaker and/or an annotation.

The apparatus is equipped with an intersection identification unit configured to generate a pixel value profile which is a profile indicating relevance between a position of each pixel in a pixel array crossing a contour and a lung field of a subject and a corresponding pixel value and a moving average profile which is a profile indicating relevance between the position of each target pixel and a moving average of a corresponding pixel value and search an intersection of both the profiles located at a position where the pixel value profile surpasses the moving average profile from a direction from a rear end to a front end of the pixel array.

Disclosed herein is a trabecular bone analyzer that can quantitatively determine the state of trabecular bone accurately. The trabecular bone analyzer of may perform trabecular bone analysis on a tomographic image D. In the tomographic image D, trabeculae forming a network may appear without overlapping. Therefore, such trabecular bone analysis may more accurately quantify trabecular bone.

Trabecular bone analyzer

A semiconductor integrated circuits can send and receive signals to and form a configuration memory. The semiconductor integrated circuits is provided therein wiht an instruction memory, an instruction storage portion that stores reserved instructions as F instructions, and stores the substantially equivalent processing contents to the F instructions as substitute instructions for processing by the CPU, a pre-fetch portion, a history storage portion, a diagnosing portion for diagnosing the types of instructions, a reprogramming control portion for reprogramming the instructions, a CPU, an FPGA, a configuration data memory, a built-in memory, and a configuration data tag. When the configuration data of the F instruction does not exist in the FPGA, the substantially equivalent processing by FPGA is executed by the CPU by making use of the substitute instructions.
