摘要： Provided is an image processing device capable of effectively displaying the details of a plurality of different branches included in a structure that is divided into a plurality of branches. An image processing device 100 reads the entire image of a coronary artery region, extracts a coronary artery region A from the read image data, displays the coronary artery region A, calculates cores 41, 42, and 43 of three coronary arteries A1, A2, and A3, and calculates the lengths of blood vessels. In addition, when an operator uses a GUI 33 that is displayed in parallel to the entire image of the coronary artery region A to designate an arbitrary scale position on the GUI 33, a CPU 101 calculates positions on the blood vessels A1, A2, and A3 corresponding to the designated scale position. The CPU 101 displays vertical tomographic images 321, 322, and 323 at the calculated corresponding positions in a detailed image display region 32.

摘要： The operability of setting movement of a Doppler sample gate for setting a Doppler measurement portion on a sectoral or circular ultrasonogram is improved. An ultrasonograph is provided with calculation means (25) for determining the position where a Doppler sample gate is displayed after the gate is moved, with reference to the current position where the Doppler sample gate is displayed, according to the amount of movement of the Doppler sample gate position input through a tack ball (23). The calculation means decomposes the amount of movement in orthogonal two-axis direction input through a track ball (23) into a component in the direction of the ultrasonic beam line of an ultrasonogram and a component orthogonal to the former component, determines the ultrasonic beam line after the movement from the decomposed orthogonal components, determines the depth position of the ultrasonic beam line after the movement from the decomposed component in the ultrasonic beam line direction, and changes the display position of the Doppler sample gate to the determined display position after the movement. Thus, the movement of the Doppler sample gate corresponds to the operation of the track ball on the screen irrespective of the position in the sectoral or circular display area, thereby mitigating the feeling of strangeness and improving the operability.

摘要： An MRI apparatus is provided in which a heat quantity penetrating into the helium tank of a superconducting magnet can be grasped to select a cryo-cooler to be incorporated, whereby consumption of liquid helium is suppressed and a static magnetic field is generated stably. The superconducting magnet includes a superconducting coil, containers 209 and 203 for accommodating the superconducting coil and a refrigerant, a cooler 208 for liquefy gas once again, the gas having been obtained by vaporizing the refrigerant in the containers, and a means for measuring the amount of vaporized refrigerant, while keeping the pressure in the containers at a constant level. The heat quantity penetrating into the containers and the coolability of the cooler are measured accurately, thereby enabling a combination in which the coolability of the cooler to be combined has capacity more than the heat penetration amount.

摘要： The dual energy X-ray CT apparatus automatically optimizes a map for separation to achieve a high degree of separation accuracy and a reduction of dose.An X-ray attenuation coefficient acquired in the dual energy X-ray CT system is applied to a map for separation which represents a relationship between the X-ray attenuation coefficient and a composition of an object, thereby separating the composition of the object. The map formation unit for separation calculates an existing probability of each composition for each combination of multiple types of X-ray attenuation coefficients, and determines the composition having the largest existing probability as the composition corresponding to the combination of the X-ray attenuation coefficients, thereby forming the map for separation. This configuration allows a formation of the map for separation with respect to each imaging condition, and high degree of accuracy in separating composition can be achieved.
