Abstract:
The present invention relates to an ultrasound system and a method of setting an intima-media thickness (IMT) measuring region. The ultrasound system comprises an ultrasound diagnosis unit configured to transmit ultrasound signals to a target object, receive ultrasound echo signals reflected from the target object and form an ultrasound image including a plurality of pixels based on the ultrasound echo signals, each pixel having an intensity of gray level. The ultrasound system further comprises a processor configured to compute intensities of the pixels at each row in the ultrasound image to form a first graph, compute first moving averages of the intensities for first subsets of rows in the ultrasound image by dividing the intensities by a thickness of a blood vessel to form a second graph, compute second moving averages of the intensities for second subsets of rows in the ultrasound image by dividing the intensities by a thickness of a vascular wall to form a third graph, and set an intima-media thickness (IMT) measuring region by using inflection points from the second and third graphs.
Abstract:
An apparatus for discharging tissue that is folded several times and stacked is provided. The apparatus includes a cartridge that holds stacked tissue and has a through hole at one end, and a holding member that is disposed adjacent to the through hole of the cartridge and pivots on an axis to grasp and remove tissues one at a time from the top of the stack through an arm. The inventive apparatus allows a user to easily replace tissue and check the amount of tissue used and the amount left to use through visual means. The apparatus virtually eliminates the problem of tissue dispensing failure, and has increased precision and reliability and reduced dispensing time over conventional apparatuses.
Abstract:
An ultrasound diagnostic apparatus for providing on a display an ultrasound image including a target object and a pointer movable on the ultrasound image, comprises: an ultrasound image providing unit configured to provide an ultrasound image including a target object; a contour line extracting unit configured to extract a contour line of the target object in the ultrasound image; a coordinate recognizing unit configured to detect cross points while the pointer crosses the contour line and recognize the coordinates of the corner points; a user input unit configured to receive instructions from a user, said instructions including a selection instruction to select measure points among the cross points and a measure instruction to measure a size of the target object; a measuring unit configured to measure a size of the target object in response to the measure instruction based on coordinates of the measure points selected in response to the selection instruction; and an output unit configured to output the ultrasound image, the pointer, the contour line, the measure points and the size of the target object.

Abstract:
A fusing unit which includes a pressure member to be elastically supported on an outer peripheral surface of a heating roller while coming into surface contact with the outer peripheral surface. The pressure member serves to grind the outer peripheral surface of the heating roller, to maintain a surface roughness of the heating roller at a predetermined level or less.
Abstract:
A system and a method of comparing ultrasound data associated with an object of interest before and after the medical treatment and providing the comparison information are disclosed. A plurality of first ultrasound data associated with an object of interest are stored before the medical treatment on the object of interest in the target body and a plurality of second ultrasound data associated with an object of interest are stored after the medical treatment on the object of interest in the target body in a storage unit. Instructions are input from a user for selecting any pair of first ultrasound data and second ultrasound data among a plurality of the first ultrasound data and a plurality of the second ultrasound data, which are stored in the storage unit. From the storage unit, the first ultrasound data and the second ultrasound data are extracted, and the extracted first ultrasound data and the extracted second ultrasound data are compared to form comparison information.
Abstract:
Embodiments for automatically finding a standard view corresponding to an acquired ultrasound image of a target object in an ultrasound system are disclosed. A mapping table associating information on a plurality of standard views of a target object with predetermined first feature vectors is stored in the storage unit. The predetermined first feature vectors may have been previously calculated from the typical plane images corresponding to the standard views. A processing unit calculates a second feature vector from an acquired ultrasound image, and refers to the mapping table to select one of the first feature vectors closest to the second feature vector. The processing unit extracts information on the standard view corresponding to the selected first feature vector from the mapping table.
Abstract:
There are disclosed embodiments for controlling an operation of an ultrasound system based on an impact applied thereto. In the ultrasound system designed to operate in a plurality of diagnostic modes, a user may be verified based on the impact pattern applied to the ultrasound system. Also, a desirable diagnostic mode of the ultrasound system may be selected and executed based on the impact pattern. The ultrasound system may include an ultrasound diagnostic unit to form ultrasound images based on ultrasound echo signals reflected from a target object. An impact detecting unit may detect impacts applied to the ultrasound diagnostic unit from a user to thereby output impact pattern information. A control unit may control an operation of the ultrasound diagnostic unit based on the impact pattern information so that the diagnostic mode corresponding to the impact pattern information may be executed.
