According to the embodiments, a medical image diagnosis apparatus which is accessible to an external medical scanner includes processing circuitry. The processing circuitry acquires from the medical scanner medical image data by imaging a subject based on a protocol which is a predetermined imaging procedure. The processing circuitry acquires from a sensor biometric information of at least when the subject is being photographed. The processing circuitry extracts characteristic information of the subject by processing the biometric information acquired up until a previous study. The processing circuitry assists a design of a protocol for a current study based on the characteristic information of the subject.

Medical image diagnosis apparatus, server and control method

An X-ray CT apparatus includes a first X-ray source, a first detector, a second X-ray source, a second detector, and processing circuitry. The processing circuitry controls the first X-ray source, the second X-ray source, the first detector, and the second detector to perform scanning. The processing circuitry acquires first data of a plurality of first detection regions and second data of a plurality of second detection regions, each of the plurality of first detection regions and the plurality of second detection regions including one detection element or a plurality of detection elements in a row direction, and the plurality of first detection regions being offset by an amount corresponding to n (0&#x3c;n&#x3c;1) of a length of each of the plurality of first detection regions in the row direction from the respective plurality of second detection regions. The processing circuitry generates image data based on the acquired first data and the acquired second data.

A medical apparatus according to an embodiment comprises a setting part, a creating part, and a display controller. The setting part is used for setting an insertion route of a puncture needle for a subject onto an image based on volume data. The creating part creates a graphic schematically indicating the volume data. The display controller displays the graphic on a display, and displays a route image corresponding to the insertion route.

Medical apparatus and X-ray CT system

A medical image processing apparatus according to an embodiment includes processing circuitry. The processing circuitry obtains a plurality of medical image groups in which respective motions of a part inside a subject have been photographed in time series and executes certain processing on the acquired medical image groups. The processing circuitry analyzes the motions in the respective medical image groups. The processing circuitry generates a medical image in which the motions in the respective medical image groups substantially match with each other based on the analyzed motions.

Medical image processing apparatus and method for medical image processing

According to one embodiment, an input unit repeatedly inputs a trigger signal originating from a specific cardiac phase from an electrocardiograph. An RR period determination unit determines whether the period between the input time point of the latest trigger signal, of repeatedly input trigger signals, and the input time point of an immediately previously input trigger signal is equal to or more than the preset first threshold, for each input of the latest trigger signal. A scan control unit terminates the generation of X-rays, if it is determined that the period is equal to or more than the first threshold.

An X-ray computer tomography apparatus includes an X-ray tube, a two-dimensional array type X-ray detector, a rotating mechanism, a pair of collimators, a collimator moving mechanism which separately moves the pair of collimators in a direction almost parallel to a rotation axis, a reconstruction processing unit which reconstructs image data in a reconstruction range, and a collimator control unit. The collimator control unit controls the position of each collimator in accordance with the distance between an X-ray central plane corresponding to a cone angle 0&#xb0; and an end face of the reconstruction range. The collimator moving mechanism moves each of the pair of collimators in the range from the outermost position corresponding to the maximum cone angle to the innermost position offset from a position corresponding to a cone angle of nearly 0&#xb0; to the opposite side.

A plurality of regions of interest can be set to be monitored. From a keyboard (,) or a mouse (,), ROI position information and CT value conditions for the ROI's are set to a ROI position information memory (,) and a ROI condition memory (,), respectively. An image reconstruction system (,) reconstructs data of a first scan stored in a projection data memory, displays as a reconstruct image (,) on a display device (,) via an image memory (,), and calculates individual representative CT values of the ROI's set as the ROI position information, storing in the image memory (,). A condition decision section (,) of a CPU (,) makes decisions of whether the representative CT values of the ROI's meet the conditions in the ROI condition memory (,), executes an operation between respective results of the decisions to decide whether the first scan is to be continued or shifted to a second scan.

A radiation computed tomography apparatus of this invention includes a couch, a top board which carries the patient and is slidably arranged on the couch, a gantry which has an opening and acquires projection data of a patient by guiding the patient carried on the top board into the opening, reconstruction section for reconstructing the tomographic image of the patient by reconstructing the projection data acquired by the gantry, and adjusting section, arranged on or near the gantry, for adjusting the photographing condition of the patient for obtaining a predetermined tomographic image of the patient.

Radiation computed tomography apparatus

A computerized tomography apparatus is disclosed which reconstructs a tomography image of data from multi-directional projection data in a period of time less than the time required for a scan operation for data acquisition and displays the tomography image after a lapse of a given period of time from the termination of the scan operation. This avoids the time interval between scan and image display becoming irregular. Accordingly, tomography images can be displayed successively like motion picture to observe the internal movements of a section of a human body under examination in real time.

Computerized tomography apparatus

A computer tomography apparatus of the present invention can select one of an ON state in which X-ray radiation is performed to continuously acquire projection data and an OFF state in which acquisition of projection data is stopped, and even in the OFF state, rotation of an X-ray tube is continued, thus allowing quick switching from the OFF state to the ON state.
