摘要： An imaging part scans a predetermined site of a subject to which a contrast agent has been administered, with ultrasound waves, and thereby acquires plural frames of ultrasound image data. A contrast agent inflow detector detects the inflow of the contrast agent into each region based on the signal intensity in each region represented in the plural frames of ultrasound image data. A reference time determining part determines, as a reference time, a time point when the contrast agent inflow detector detects the inflow of the contrast agent into a first region of interest. A color coding part obtains a relative time of the inflow of the contrast agent into each region with reference to the reference time, and generates image data representing the color of each region with a hue corresponding to the relative time. An image based on the image data representing the hue is displayed.

摘要： According to one embodiment, a detector detects a position at a leading end of a puncture needle. A determination unit determines a first scanning region in a subject and a second scanning region based on the position at the detected leading end, the second scanning region being narrower than the first scanning region. A transmission/reception controller controls a transmitter and a receiver to switches between first ultrasonic scanning for the first scanning region and second ultrasonic scanning for the second scanning region according to an instruction from an operator.

摘要： According to an embodiment, an image generating unit generates a medical image. A deciding unit detects a reaching time at which a contrast agent has reached a predetermined region of the medical image. The deciding unit sets a color map in which the reaching time is associated with a hue based on a first inflow time corresponding to a first designation region set to the medical image and a second inflow time corresponding to a second designation region. A generating unit generates a hue conversion image in which a hue is allocated to each region of the medical image based on the color map and the reaching time in each region of the medical image. A control unit displays the hue conversion image through a monitor.
