Abstract: The present disclosure relates to the field of ultrasonic detection, in particular to a craniocerebral ultrasonic standard plane imaging and automatic detection and display method for abnormal regions. The following technical solution is adopted: contour detection is performed on the scanned ultrasound images the skull to construct a skull surface model, and the standard planes in ultrasound images are identified and extracted according to the skull surface model. The symmetry of the standard planes in ultrasound images is used to compare the similarity, so as to obtain the abnormal regions for segmentation and display. The advantages of the present disclosure are as follows: the skull surface model is constructed by detecting the cranial edge, and the coordinate system is established based on this model, thereby the standard planes in ultrasound images can be quickly identified from the scanned ultrasound images.

Abstract: A joined material and a method of manufacturing the joined material are provided which enable a metal layer and a carbon material layer to be easily joined to each other while making the thickness of the metal layer larger and which can inhibit failure. A joined material includes a CFC layer (3) and a tungsten layer (4) that are joined to each other. A sintered tungsten carbide layer (5), a mixed layer (6) of SiC and WC, and SiC and WC (7) that have been sintered while intruding into the CFC layer (3), are formed between the CFC layer (3) and the tungsten layer (4), and these layers (3, 4, 5, 6, and 7) are joined to each other by sintering.

Abstract: Achieved is a ceramic carbon composite material and a ceramic-coated ceramic carbon composite material which are lighter than ceramics and excellent in at least one of properties including oxidation resistance, resistance to dust generation, heat conductivity, electrical conductivity, strength, and denseness. The ceramic carbon composite material is a ceramic carbon composite material in which an interfacial layer of a ceramic is formed between carbon particles of or containing graphite. The ceramic carbon composite material can be produced by forming a green body from ceramic-coated powder in which the surfaces of carbon particles of or containing graphite are coated with individual ceramic layers and sintering the green body.

Abstract: In a method for controlling characteristics of a ceramic carbon composite, an interfacial layer of a ceramic is formed throughout a carbonaceous material and the interfacial layer of the ceramic has a continuous three-dimensional network throughout the carbonaceous material; and characteristics of a ceramic carbon composite are controlled. In a method, an interfacial layer (3) of a ceramic is formed throughout a carbonaceous material (2) and the interfacial layer (3) of the ceramic has a continuous three-dimensional network throughout the carbonaceous material (2), the characteristics of the ceramic carbon composite (1) is controlled by specifying and selecting at least one of a shape, a hardness, and a degree of graphitization of the carbonaceous material (2). Thus, the ceramic carbon composite (1) having the characteristics controlled without depending on the control of manufacturing conditions can be obtained.
