  • Patent number: 10413270
    Abstract: 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.

  • Patent number: 9480460
    Abstract: 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.

  • Patent number: 8724880
    Abstract: 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.

  • Patent number: 8267867
    Abstract: 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.

  • Patent number: 5416238
    Abstract: Novel N.sup.G -protected or unprotected-L-argininal-dibutyl acetals (I) can be prepared from L-argininal derivatives (III) merely by reacting in an azeotropic solvent in the presence of p-toluenesulfonic acid. In the products (I), L-form amounts to more than 99%, without further optical resolution. The L-argininal acetals (I) are useful as starting materials for preparing peptidyl-L-argininal derivatives which can provide protease inhibitors or ligands used for affinity chromatography of various proteases.
