Abstract:
1. An apparatus comprising: one or more processors, and a machine-readable medium for storing instructions thereon which when executed by the one or more processors cause the one or more processors to perform operations comprising the following steps: (a) determining radiation dose values for a response matrix by determining a radiation dose value for each radiation field in a response matrix from a plurality of detector elements of a dosimeter, (b) determining a final net radiation dose value for each radiation field in the response matrix, and (c) displaying the final net radiation dose value for each radiation field in the response matrix to a user and/or saving the final net radiation dose value for each radiation field to a first storage medium, wherein each radiation field has a radiation source, wherein step (b) comprises conducting a numerical optimization process comprising the following steps: (i) generating an initial solution vector for each radiation field, (ii) iteratively updating the initial solution vector for each radiation field until an objective function is minimized to thereby generate an optimal solution vector, and (iii) determining a radiation dose value for each radiation field based on the optimal solution vector for the source, wherein the objective function is wherein the objective function is where min is the minimized objective function, where i is the number of detector elements of the dosimeter, where cv wherein cv wherein each stored response is one of a plurality of stored responses stored on a second storage medium.
