Abstract: In a medical image processing apparatus 100 that is capable of extracting a contour of an organ or the like in a highly accurate manner within a short time, an image input unit 101 accepts ultrasound images or the like. An electrocardiographic information input unit 102 accepts electrocardiographic information (e.g. ECG waveform). A storage unit 103 stores image data representing the ultrasound images and the electrocardiographic information in association with each other. A dictionary storage unit 104 stores image patterns (dictionary images) used for pattern matching. A pattern dictionary selection unit 105 selects a dictionary image used for pattern matching with reference to the electrocardiographic information. A pattern search range setting unit 106 specifies a range in which pattern matching is to be performed, based on the electrocardiographic information. A cardiac area identification unit 107 detects a cardiac area in the image.

Abstract: In an ultrasonic diagnostic apparatus (100) capable of generating an ultrasound image equivalent to one generated by combining images shot from various angles, without causing problems concerning an increased number of hardware pieces and a decreased frame rate, a pulsar (12) generates pulse signals for emitting ultrasound based on trigger signals received from a control unit (11), and outputs such signals to a group of transducers (1) via an amplifier (13). The group of transducers (1) receives ultrasonic echoes from a scatterer. A buffer (17) stores the reflected signals received via a delayer (14) and an A/D converter (16). A reflection angle detection unit (18) specifies a reflection angle and a reflection strength pattern of the reflected signals, and a weighting/addition unit (15) performs weighing based on such reflection strength pattern. A detection unit (19) performs detection, and a display unit (20) displays an ultrasound image and the reflection angle.

Abstract: Information necessary for authenticating a target (target information) is obtained by a target information obtainment unit 11 and a user input unit 12. Obtained target information is inputted in an authentication target information processing unit 40 via an operation control unit 30, and a person, an item and the like are authenticated by a target information authentication unit 41. Also, location information necessary for identifying a present location by a GPS data receiving unit 51 or a location information receiving unit 52. This location information is obtained from a base station and the like of a GPS satellite, a cellular phone and a PHS. Location information authentication unit 71 authenticates a location based on the obtained location information and information stored in a storage unit 90 in advance. Location information DB 72 is used at the time of this authentication.
