First RGB image signals are inputted. Color difference signals Cr and Cb are calculated from the first RGB image signals. In a feature space formed by the color difference signals Cr and Cb, a first process and a second process are performed. In the first process, coordinates which correspond to the first, second, and third observation areas are moved in a parallel manner such that the coordinates which correspond to the second observation area are moved to a reference area that contains the origin point. In the second process, the coordinates which correspond to the first observation area and the coordinates which correspond to the third observation area are moved away from each other.

First RGB image signals are inputted. A first B/G ratio and a first G/R ratio are calculated. The first B/G ratio and the first G/R ratio are converted into a second B/G ratio and a second G/R ratio, respectively, through a color information conversion process. Owing to the color information conversion process, a difference between first and second observation areas in a second signal ratio space formed by the second B/G ratio and the second G/R ratio is greater than a difference between the first and second observation areas in a first signal ratio space formed by the first B/G ratio and the first G/R ratio, and a difference between the first and third observation areas in the second signal ratio space is greater than a difference between the first and third observation areas in the first signal ratio space.

First, second, and third areas are located in a feature space formed by the B/G and G/R ratios. An equal angular magnification process is performed on an angle in a region R1x including a first reference line passing through the second area. An angle expansion process or an angle compression process is performed on an angle in a region R1y located outside the region R1x. An equal radial-coordinate magnification process is performed on a radial coordinate in a region R2x, which includes a second reference line passing through the second area and intersecting the first reference line. A radial-coordinate expansion process or a radial-coordinate compression process is performed on a radial coordinate in a region R2y located outside the region R2x.

Complex diagnostic apparatus, complex diagnostic system, ultrasound diagnostic apparatus, X-ray diagnostic apparatus and complex diagnostic image-generating method

A radiological image detection apparatus includes an imaging unit, a storage unit, a correction data generating unit, a correction unit, a disturbance detection unit, and a determination unit. The imaging unit acquires radiological image data. The storage unit stores correction data for correcting the radiological image data. The correction data generating unit generates new correction data based on dark image data and updates the correction data stored in the storage unit. The correction unit performs a correction process for the radiological image data using the correction data. The disturbance detection unit detects a disturbance acting when the imaging unit acquires the dark image data. The determination unit determines whether the updating of the correction data stored in the storage unit is permitted, or whether the acquisition of the dark image data is permitted, based on the detection result of the disturbance detection unit.

Radiological image detection apparatus

An AEC signal is transmitted and received always in a wireless manner between a wireless communicator of an electronic cassette and a wireless communicator of a control device, regardless of the presence or absence of wired communication. If communication failure occurs in the wired communication and X-ray image data cannot be transmitted in a wired manner, a memory of the electronic cassette temporarily stores the X-ray image data. Since the AEC signal is wirelessly transmitted, X-ray imaging is continued even if the wired communication is unusable. A cause of the communication failure is more easily identified in wireless communication than in the wired communication. Thus, even if the communication failure occurs in the wireless communication, the wireless communication quickly recovers from the failure and downtime of an X-ray imaging system does not become too long.
