Claim Text:
1. A computer-implemented method for use in detecting an air pocket in a single crystal material, said method comprising: providing a matrix including a plurality of data units and a center, the plurality of data units including image data related to a region of interest of the single crystal material; defining a first half and a second half of the matrix based on a first axis passing through the center of the matrix; determining, by a processor, a difference between each data unit of the first half and a corresponding data unit of the second half; calculating, by the processor, a first index value based on the determined differences; defining a third half and a fourth half of the matrix based on a second axis passing through the center of the matrix, the second axis being different than the first axis; determining, by the processor, a difference between each data unit of the third half and a corresponding data unit of the fourth half; calculating, by the processor, a second index value based on the differences of the corresponding data units of the third and fourth halves; and identifying an air pocket within the single crystal material based on the first index value, the second index value, and a predetermined threshold.
