Abstract: A radiation imaging system includes a radiation imaging apparatus configured to transmit, based on electric charge generated in response to irradiation with radiation and a target value, a signal related to control of irradiation with radiation to an external apparatus; and a control apparatus configured to generate a target dose index value that is based on the target value and a dose index value that is based on information regarding electric charge, and determine whether the dose index value is within an allowable range of the target dose index value.

Abstract: A medical image processing apparatus includes a processing unit configured to process, using learning result data that is at least one or more pieces of learning result data obtained by machine learning and is selected based on imaging information, a medical image obtained based on the imaging information, the imaging information including information regarding a radiation detection apparatus used for imaging.

Abstract: A biological information displaying apparatus according to an embodiment includes a picture obtaining apparatus and a processor. The picture obtaining apparatus obtains a picture signal of a predetermined site of a subject as a moving image. The processor generates a hue moving image by extracting a luminance or an image-based photoplethysmogram (iPPG) related to a pulse wave for each pixel of the moving image and assigning a hue in accordance with a value of luminance information or iPPG information. The processor displays the generated hue moving image such that the hue moving image is superimposed on an image of the subject.

Abstract: A biological information measuring apparatus according to an embodiment includes a calculating unit and a measuring unit. The calculating unit is configured to calculate information related to a pulse wave of a subject, on the basis of luminance information of a picture signal of the subject. The measuring unit is configured to measure a fluctuation of blood pressure of the subject based on an increase or a decrease in the information related to the pulse wave, in accordance with a site of the subject from which the picture signal was obtained.

Abstract: A radiographing apparatus includes a selecting unit configured to select a target dose index for radiographing based on a radiographing imaging mode, a dose index acquiring unit configured to acquire a dose index from image data based on radiation transmitted through a subject, and a calculating unit configured to calculate a deviation index of the dose index with respect to the target dose index. Alternatively, the radiographing apparatus may include a display control unit configured to display, on a display unit, information regarding the imaging mode, the target dose index and the dose index.

Abstract: An apparatus includes an acquisition unit configured to acquire a first image and a second image obtained by detecting radiation of different energies, and a subtraction image generated using the first image and the second image, and an output control unit configured to control output of the first image, the second image, and the subtraction image based on examination information.

Abstract: An apparatus includes a setting unit and an obtaining unit. The setting unit is configured to set an order of transmission for first data and second data, the first data being obtained by using radiation having first energy, the second data being obtained by using radiation having second energy that is lower than the first energy. The obtaining unit is configured to obtain the first data and the second data that have been transmitted in the set order of transmission.
