1. A method for examining a measurement object, which comprises: exposing the measurement object to invasive radiation; detecting an interaction of the invasive radiation by way of a radiation-sensitive sensor device; calculating expected detection results of the sensor device by using a setpoint geometry of the measurement object and by using material properties, wherein each of the expected detection results corresponds to one of a different position and a different alignment of the measurement object relative to at least one of the radiation source and the sensor device; comparing the expected detection results with an actual detection result for determining which of the expected detection results corresponds best with the actual detection result; and deriving therefrom information relating to at least one of the position and/or alignment of the measurement object relative to the radiation source and/or relative to the sensor device.
