  • Patent number: 12124337
    Abstract: A data store volume (DSVOL) for a snapshot group which is a group of the PVOL and one or more SVOLs for the PVOL is a data storage region where data of which a storage destination is one volume (VOL) of the snapshot group and meta-information of the data are stored, and the meta-information is information including address mapping between a reference source address which is an address of a position of the data in the snapshot group and a reference destination address which is an address of a position of the data in the DSVOL. A process of a storage system increases the number of DSVOLs in the snapshot group when an input/output (I/O) load on the snapshot group exceeds a threshold.

  • Patent number: 8768436
    Abstract: By a CPU (101) of a device (100) for processing medical image, a coronary artery region and a cardiac muscle region that are to be analyzed are extracted from angiographic images of the coronary artery obtained from X-ray CT images or the like. Next, degrees of isolation (blood vessel dependences), which indicate the effects of the coronary artery on the individual sites of the myocardium, are calculated. The calculated degrees of isolation are referred to as pixel values and displayed while superimposed on a bull's eye map of the cardiac muscle, a three-dimensional image of the heart or the like. As a result, the effect of infarction or constriction on the cardiac muscle region can be visually recognized merely by using the angiographic image data of the coronary artery without conducting a delay angiographic imaging examination or the like.

  • Patent number: 8693759
    Abstract: 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.

  • Patent number: 8503746
    Abstract: A medical image processing device etc. which supports work for precisely identifying the area of a diagnosis object from a medical image scanned by a medical imaging apparatus is provided. A CPU (11) of the medical image processing device (1) inputs image data and stores the same in a main memory (12) (S101). Next, the CPU (11) subjects the inputted image data to threshold processing (S102). Next, the CPU (11) stores, in the main memory (12), data obtained by separating the area of the high signal values of the binarized image data into a bone region and an angiographically scanned region (S103). Next, the CPU (11) identifies the contact area of the bone region and the angiographically scanned region from the data stored in the main memory (12) (S104). Next, the CPU (11) emphasizes the contact area stored in the main memory (12) at the S104 and displays the contact area on a display device (15) (S105).

  • Patent number: 7921677
    Abstract: A vehicular upholstery fabric is made from a raw tricot fabric which is knitted by using a PPT-multifilament yarn whose single fiber fineness is about 0.5˜6.0 dtex and whose total fineness is about 30˜180 dtex for the ground yarn and the pile yarn. The raw tricot fabric has been transformed into a napped tricot pile fabric by raising the sinker loop of the pile yarn of the raw tricot fabric to form fluffs which are then sheared to form cut piles. A PPT-bulky multifilament yarn is used for the ground yarn. A PPT-non-bulky texturized multifilament yarn or a PPT-bulky texturized multifilament yarn is used for the pile yarn.
