The invention relates to a method for the automated determination of characteristic curves and/or characteristic maps of devices, which comprises the following method steps: acquisition of a measurement data set, execution of an iteration method with the iteration steps calculation of an iteration result from the measurement data set using a neural network, acquisition of a termination parameter, checking the termination parameter and terminating the iteration method if the termination parameter matches a termination criterion, as well as the optical visualization of the iteration result and the measurement data set and repeating the iteration steps.

A tool management system of machine tools includes a reader, a receiver, a storage unit, a processor and a control unit. The reader is configured for reading at least one category parameter of the tool according to a tool index code of the tool. The receiver is configured for receiving real-time process information of the tool with a preset periodicity. The storage unit is configured for storing the tool index code, the category parameter, and the real-time process information. The processor is configured for processing a weighting algorithm to obtain a result according to the category parameter and the real-time process information. The control unit is configured for sending a control instruction according to the result.

The present invention concerns a radiation inverse treatment planning system for a linear accelerator. The system includes a radiation source, configured for delivering individual radiotherapeutic dose shots (aj), each individual radiotherapeutic dose shot having a predetermined location and incidence angle inside and/or outside a target area, a size and a shape. The system also includes at least a data bus system (102), and a memory (106) coupled to the data bus system (102), wherein the memory (106) includes a computer usable program code. The system also includes a processing unit (104) coupled to the data bus system (102), wherein the processing unit (104) is configured to execute the computer usable program code to pre-compute (10) a set of individual radiotherapeutie dose shots (aj), and associate (40) a weight (sj) to each individual radiotherapeutic dose shot (aj), based on one or more constraints (20). The processing unit (104) executes the computer usable program code to find (30) the sparsest subset of individual radiotherapeutic dose shots, so as to satisfy said one or more constraints (20).
