The display control unit is configured to perform control to display a signal source in a superimposed manner on a plurality of biological tomographic images sliced in a predetermined direction, the signal source corresponding to a part of biological data indicating a temporal change of a biological signal, and initially display, in a display region of a screen of a display unit, a biological tomographic image on which a predetermined signal source is superimposed among the plurality of sliced biological tomographic images.

A medical image diagnostic system of an embodiment includes a processing circuit which is configured to control transition between a plurality of steps included in a workflow for examining a subject. The processing circuit is configured to acquire first information representing a preparation state of the subject in a first step among the plurality of steps, is configured to acquire second information representing permission for transition from the first step to a second step, and is configured to control transition from the first step to the second step on the basis of the first information and the second information.

A radiation imaging control apparatus includes a hardware processor and an operator. The hardware processor obtains an examination order and one or a plurality of radiation irradiating parameters corresponding to each examination order. The examination order to be executed is selected using the operator. When the examination order is selected on the operator, the hardware processor determines a selecting condition according to a priority setting from a plurality of selecting conditions, and selects a radiation irradiating parameter for the examination order from one or a plurality of radiation irradiating parameters according to the determined selecting condition.

A radiation imaging system is provided. The system comprises a radiation imaging apparatus including a plurality of pixels for acquiring radiation image data and a detection unit for performing exposure control during radiation irradiation, and a radiation control apparatus configured to control a radiation source that irradiates radiation to the radiation imaging apparatus. The radiation imaging apparatus and the radiation control apparatus transmit signals that relate to exposure control by wireless communication. The radiation imaging apparatus, in a case where an irradiation stop signal indicating that radiation irradiation has been stopped is not received from the radiation control apparatus after a signal instructing to stop radiation irradiation has been transmitted to the radiation control apparatus and until a first time interval has elapsed, transmits a signal instructing to stop radiation irradiation to the radiation control apparatus again.

In a mobile X-ray apparatus including a power supply supplying operation power, the power supply may include: a battery pack including a plurality of battery cells; a battery management system configured to control the operation power to be supplied from the battery pack to at least one component of the mobile X-ray apparatus; and a monitoring integrated circuit configured to monitor a voltage of the plurality of battery cells and control monitoring power supplied from the plurality of battery cells, based on whether the operation power is supplied to at least one component of the mobile X-ray apparatus.

Methods and systems are provided for powering an imaging system. In one embodiment, a system comprises a direct current (DC) bus, an x-ray source coupled to the DC bus, a power distribution unit (PDU) with an input coupled to a three-phase alternating current (AC) source and an output coupled to the DC bus, and an energy storage apparatus comprising a supercapacitor, the energy storage apparatus coupled to the DC bus and configured to store electrical energy output by the PDU in the supercapacitor, and output the stored electrical energy directly to the DC bus for powering the x-ray source. In this way, an x-ray source of an imaging system may be adequately powered beyond the limitations of a PDU without upgrading the electrical utilities of a hospital and without upgrading the PDU. The supercapacitor is protected by FPGA by measuring input current, voltage, temperature, and voltage balance.

A digital dental x-ray sensor device includes a rounded, three dimensional housing that lacks corners, edges, or other relatively sharp features that are known to cause discomfort when used in a patient's mouth. The rounded three dimensional housing can be spherical, ellipsoid, or any similar regular or irregular rounded shape, and can be formed by ensuring that all curves of a surface of the rounded three dimensional housing have a minimum radius that is sufficient to prevent features that can dig into a soft tissue of the inside of a patient's mouth.
