20120177265 | MEDICAL IMAGE DIAGNOSIS APPARATUS AND IMAGE PROCESSING APPARATUS AND METHOD - 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. | 07-12-2012 |

20150018677 | ULTRASOUND DIAGNOSIS APPARATUS AND CONTROL METHOD - An ultrasound diagnosis apparatus includes a transmitter/receiver, a signal processor, and an image generator. The transmitter/receiver transmits, at least once in each scanning line, a first ultrasound pulse and a second ultrasound pulse whose amplitude corresponds to amplitude of the first ultrasound pulse modulated at a given ratio and acquires a received-signal group consisting of multiple received signals. The signal processor acquires, on the basis of a coefficient that reduces the energy of a first composite signal that is obtained by combining, in accordance with the given ratio, multiple received signals contained in the first received signal group acquired by the transmitter/receiver, a second composite signal by combining multiple received signals contained in a second received signal group that is acquired by the transmitter/receiver and that is different from the first received signal group. The image generator generates an ultrasound image based on the second composite signal. | 01-15-2015 |
