Computer-implemented method for monitoring the status of a device for investigating objects

A computer-implemented method for monitoring the status of a device for investigating objects, wherein the investigation of an object involves determining measurement data by measuring the object and operating data of the device is determined during the investigation of the object, wherein the method comprises the following steps:

• determining measurement data of the object by means of the device;
• determining operating data of the device during the step of determining measurement data of the object;
• determining at least one quality parameter from the measurement data;
• analyzing the operating data and the at least one quality parameter;
• determining a status characteristic value based on the analysis of the operating data and the at least one quality parameter in order to monitor the status of the device, wherein the status characteristic value indicates a status of the device;
• carrying out at least the step of determining measurement data of the object with a first object, wherein the measurement is a radiographic measurement;
• carrying out at least the step of determining measurement data of the object with a second object, wherein the measurement is a radiographic measurement, wherein a different radiographic geometry is used than for the first object;
• determining projection representations from the measurement data of the first object;
• determining projection representations from the measurement data of the second object;
• comparing at least one blurring between the projection representations of the first object and the projection representations of the second object;
• and
• analyzing the at least one blurring to determine the status characteristic value.
