摘要： A patient monitoring method and apparatus for a medical imaging device are provided, which subject an examination subject positioned in the medical imaging device to real-time image capture. Two images are sampled spaced apart by a specified time and captured by a camera, and a difference is calculated to obtain a difference image matrix. The difference image matrix is used to determine whether the examination subject has moved using a predetermined threshold. A display presents an image captured by the camera in a pop-up window when it is determined that the examination subject has moved such that a medical imaging scan operating interface and the image captured by the camera are presented together. The display only presents the medical imaging scan operating interface (not an image captured by the camera) when it is determined that the examination subject has not moved.

摘要： A hospital bed may include a bed frame, a first bed board and an auxiliary component. The first bed board is connected to the bed frame. The auxiliary component may include a connecting frame, a first moving and supporting mechanism and a second bed board. The connecting frame is detachably connected to the first bed board. The first moving and supporting mechanism is connected to the connecting frame. The second bed board is connected to the first moving and supporting mechanism and can carry an object along the bearing direction. The second bed board is arranged on one side of the first bed board along the bearing direction. The first moving and supporting mechanism can drive the second bed board to move relative to the first bed board along an adjustment direction, where the adjustment direction is perpendicular to the bearing direction.

摘要： In a protocol parameter selection method and corresponding device, when previewing a current sequence in multiple predetermined sequences, a corresponding reference performance index radar chart is displayed in a standard radar chart, according to a reference value of each performance index in multiple performance indices obtained in advance on the basis of the current sequence. The standard radar chart is a radar chart generated using the multiple performance indices as components and using as a standard a standard value of each performance index obtained in advance on the basis of at least one sequence. The method and device also include determining, as a sequence required for scanning, a current sequence selected according to the reference performance index radar chart and a performance index currently of interest.

摘要： A digital mode matrix phase calibration includes acquiring an actual phase deviation θ′mn forming an actual phase deviation matrix θ′ of a factory system; calculating an ideal phase deviation forming an ideal phase deviation matrix; calculating a phase deviation of the actual phase deviation and the ideal phase deviation; acquiring a maximum value of the phase deviation; when the maximum value Δθmax is less than a preset threshold δ, calculating a field system phase deviation θ″mn, and a field system phase deviation matrix θ″ formed by the field system phase deviation θ″mn subjecting a field system to phase calibration. By acquiring only one row and one column in the phase deviation matrix, the technical solution in embodiments of the present invention can fit phase deviations of other rows and columns, and the method subjects the system to phase calibration quickly.
