摘要:
A diagnostic device has a modality for generating raw data representing contents of a volume, a computer for calculating three-dimensional medical images from the raw data, an image system, an input device for setting a transfer function required for an algorithm and a display device for the medical images. The image system determines a histogram distribution of the gray-scale values, and the image system inserts user interface graphics into the displayed image which shows the histogram distribution of the gray-scale values in a histogram window and symbolically represents a trapezoidal transfer function on which values characterizing input fields for transfer functions are arranged at the associated points. A transfer function is on the basis of entries in the input fields and the selected transfer function is inserted in the histogram distribution of the gray-scale values.

A control system, a method of operating the same, and a method for setting up the same are disclosed for simplified driving of a function unit parametrized by a plurality of input variables. The control system includes a setting unit and a control unit, the setting unit being used to set a number of prescribed control parameters and to feed them to the control unit. A value tuple that is fed to the function unit for the parametrization thereof is determined by the control unit as a function of the controlled variables in accordance with a stored interpolation function based on interpolation points. To set up the control system, it is provided to select a number of value tuples of the input variables as interpolation points from a parameter space defined by the input variables, and to determine the interpolation function in such a way that it defines a continuous subspace of the parameter space which has a dimensionality corresponding to the number of controlled variables and contains every interpolation point.
