An X-ray CT apparatus includes: intensity distribution data acquiring circuitry is configured to acquire, by performing a first scan, intensity distribution data of X-rays being radiated from an X-ray tube and having passed through a subject; scan controlling circuitry is configured to estimate an X-ray dose with which it is possible to discriminate individual X-ray photons having passed through the subject based on the intensity distribution data and to cause a second scan that is for a photon counting CT purpose to be performed by causing the estimated dose of X-rays to be radiated from the X-ray tube to the subject; a counting result acquiring circuitry is configured to acquire, by the second scan, a counting result by counting the X-ray photons being radiated from the X-ray tube and having passed through the subject; and an image reconstructing circuitry is configured to reconstruct X-ray CT image data based on the counting result.

X-ray CT apparatus and controlling method

A magnetic resonance imaging (MR) apparatus includes a mode switching part and an imaging system. The mode switching part is configured to put a circuit system consuming power into a shutdown state when a first trigger has been detected and to put the circuit system back into a startup state when a second trigger has been detected. The first trigger shows that MR imaging does not start for a certain period. The second trigger shows that MR imaging starts. The imaging system is configured to perform MR imaging by using the circuit system after being set to the startup state.

Magnetic resonance imaging apparatus and magnetic resonance imaging method

According to one embodiment, a magnetic resonance imaging apparatus includes a mode switching part and an imaging system. The mode switching part is configured to put a circuit system consuming a power into a shutdown state when a first trigger has been detected and put the circuit system being the shutdown state into a startup state when a second trigger has been detected. The first trigger shows that an imaging does not start for a certain period. The second trigger shows that the imaging starts. The imaging system is configured to perform the imaging by using the circuit system being the startup state.

According to one embodiment, an X-ray CT apparatus includes a data acquiring unit, a data processing unit and a data transmitting unit. The data acquiring unit is configured to expose an X-ray to an object, acquire detection data of the X-ray having transmitted the object and compress the detection data to generate compressed data. The data processing unit is configured to generate X-ray CT image data of the object based on the compressed data transmitted from the data acquiring unit through a transmission line. The data transmitting unit is configured to transmit uncompressed detection data of an X-ray to the data processing unit through the transmission line according to information from an input device.

X-ray CT apparatus and data transmission method of X-ray CT apparatus

A portable ultrasound diagnosis apparatus includes: an ultrasound probe that transmits and receives an ultrasound wave to and from a subject; a processing unit being connected to the ultrasound probe and including a generating unit that generates image data of the subject on the basis of an ultrasound signal received by the ultrasound probe; a display controlling unit that exercises control so as to cause the image data to be displayed by an information terminal being connected to the processing unit and having a display unit; and an identifying unit that performs an identifying process on the basis of identification information of the information terminal. The display controlling unit exercises control so that the information terminal displays a diagnosis image area while varying the size thereof relative to the size of the display unit, in accordance with a result of the identifying process by the identifying unit.
