According to one embodiment, a medical image diagnosis system includes a gantry, a rail, an absorbing member and a carrier unit. The rail is disposed on a floor. The rail cover covers the rail. The absorbing member is formed between the floor and the rail cover. The carrier unit is formed in a bottom of the gantry, and is moved along the rail through a space between the rail and the rail cover, and along with movement, attaches and detaches the rail cover with respect to the floor via the absorbing member.

Medical image diagnosis system

According to one embodiment, a medical image diagnostic apparatus includes a holding device, a driving unit, a first encoder, a second encoder, and processing circuitry. The holding device holds an X-ray generator and an X-ray detector such that the X-ray generator and the X-ray detector are rotatable. The driving unit transmits a rotating force of a driving motor to a rotation axis through a power transmission mechanism. The first encoder detects a rotation of the driving motor. The second encoder detects a rotation of the rotation axis. The processing circuitry detects an abnormal state of the power transmission mechanism, based on a time difference between a first pulse output from the first encoder and a corresponding second pulse output from the second encoder.

Medical image diagnostic apparatus

An ultrasonic diagnostic apparatus includes an memory, an determination unit, an instruction unit, a specifying unit, and an redetermination unit. The memory stores upper limit values of parameters for restricting the powers in display modes. The determination unit determines the powers in the modes so as not to exceed upper limit values of the parameters. The instruction unit inputs an instruction to increase/decrease the power of a specific mode. The specifying unit specifies the parameter value in the specific mode. The redetermination unit determines an upper limit value of the parameter in a mode different from the specific mode based on the upper limit value of the parameter in the specific mode and the parameter value specified by the specifying unit.

Ultrasonic diagnostic apparatus and ultrasonic wave transmission/reception control method

An ultrasonic diagnostic apparatus has a unit which sets a display region for displaying a 3D image, a unit which transmits and receives ultrasound waves, a unit which generates volume data, a unit, on the basis of the volume data, which sets an analysis region, a unit, on the basis of the data on the analysis region contained in the volume data, which analyzes a fluctuations in signal intensity over time, a unit, on the basis of the analysis result, which calculates a cardiac cycle, a unit, on the basis of the cardiac cycle and the volume data, which generates data set constructed by data with substantially equal cardiac cycle, and generates data sets corresponding to a plurality of cardiac cycles, and a unit which displays the 3D images based on the data sets as a moving image.

Ultrasonic diagnostic apparatus and controlling method of ultrasonic diagnostic apparatus

According to one embodiment, a gain adjustment unit executes gain adjustment for 3D B-mode data using gain adjustment values respectively decided for the depth on each scanning line, azimuth direction and elevation direction in a scanned region. A threshold decision unit decides a threshold used for discriminating lumen and non-lumen regions in the scanned region using the gain-adjustment-executed 3D B-mode data. A threshold processing unit executes threshold processing to discriminate data concerning the non-lumen region from the gain-adjustment-executed 3D B-mode data, using the threshold. An image generation unit generates an ultrasonic image concerning the lumen region based on the threshold-processing-executed 3D B-mode data.

Ultrasonic diagnostic apparatus and medical image processing apparatus

An ultrasound image diagnosis apparatus and a method for setting an ultrasound drive voltage by which appropriate probe motion parameters are established by individually estimating temperature changes which occur due to a plurality of heat sources existing within the probe. By individually storing or correcting relative temperature change data associated with motion parameters due to a plurality of heat source elements, an optimum driving voltage for the ultrasound transducers is set. Since a transmission drive voltage is larger than the conventional drive voltage can be set under a permissible probe temperature, image diagnosis can be improved.

By using the input unit, a condition previously regarded necessary, for example, some parameter values of a plurality of frequencies are registered as a group. The registered parameter values are stored in a memory within the apparatus setting condition controlling unit. An operator selects a desired group at a diagnosis time, and selects a parameter value to be used for diagnosis, from a plurality of parameter values forming the group. The apparatus operates based on the operational condition defined by the parameter value, to make a diagnosis.
