A medical image processing device such as an ultrasonic diagnosis device, wherein an observation point tracking process is sequentially performed between each of the adjacent frames in a frame sequence. The observation point thereby moves from the start coordinates to the end coordinates in a single heartbeat period. The difference between the coordinates is the error vector, and the total correction amount is obtained from the error vector. The total correction amount is adaptively allocated to individual frames to be corrected in the expansion period. More specifically, the allocated amount for each of the frames to be corrected is calculated on the basis of the amount of movement of the observation point representing the error indicator value obtained for each of the frames to be corrected. A larger allocation amount is applied for a larger amount of observation point movement, and a smaller allocation amount is applied for a smaller amount of observation point movement. It is thereby possible to naturally correct each of the observation point coordinates.

[Problem] To provide a device for detecting fluid flow rate, the device being capable of obtaining assessments that are medically appropriate. [Solution] The velocity of a fluid flowing in a luminal tissue inside a living body is determined. Vθ(r, θ) = w∙V-θ + (1-w)∙V+θ is computed to compute a calculated value Vθ(r, θ) for the fluid flow rate of the component orthogonal to the direction of the ultrasound beam. For at least a previously determined distance from one wall of the tissue, the weight (w) here is a value that is proportional to the distance (d) from the one wall and for a previously determined distance from the other wall of the tissue, the weight is proportional to the distance (d') from the other wall.
This portable ultrasonic diagnostic device is provided with a frame housing a substrate internally, a battery which is housed in a battery housing unit provided inside the frame and which supplies power to the aforementioned substrate, an intake opening which is disposed in the battery housing unit and which intakes air from around the battery or substrate which has been heated by heat generated by the battery or substrate, a flow path which guides the air from around the battery or substrate taken in through the intake opening, and an exhaust opening which discharges the air from around the battery or substrate which has passed through the flow path.
In order to provide technology for limiting the deterioration of hardware in a portable diagnostic ultrasound apparatus without increasing user workload, internal processing of the portable diagnostic ultrasound apparatus is controlled according to the opening or closing of the cover case in which the monitor is disposed. In particular, when the cover case is closed, not only is output of ultrasonic waves stopped but processing that is being executed inside the apparatus is appropriately terminated and the power is turned off. When so doing, processing that is being executed is interrupted and cancelled and processing that is waiting to be executed is cancelled. The cancelled information is stored in a storage device.
In ultrasound images, there are many stationary echoes in the region superficial to the deep region comprising the heart. In the present invention, a HPF processing unit (20) filters frame data by applying a high pass filter, the characteristics of which have been set according to the depth in the frame, on the frame data at said depth. The high pass filter can be achieved, for example, with a digital filter and the characteristics of the high pass filter are adjusted by the filter-setting unit (22) setting the filter coefficient of said digital filter. That is to say, the filter coefficient in the HPF processing unit (20) is controlled by the filter-setting unit (22) so that the deeper the region, the higher the offset level is set.

In an ultrasonograph, a scan converter module generates display frame data from received frame data using a conversion table adapted to the specific display resolution of a display device. Received frame data is stored in a first frame memory, and display frame data is stored in a second frame memory. A control unit selects the conversion table corresponding to the specific display resolution of the display device from among a group of conversion tables. An address converter generates an address set corresponding to a display address using the selected conversion table. Interpolation is then performed based on the encoder data specified by this.
