    Design an algorithm to calculate the total scanning boundary of a pentagonal medical imaging sensor used in diagnostic equipment, where the boundary length determines the tissue coverage area for disease detection. The sensor has equal sides of length 'a' millimeters, and the total boundary length is crucial for ensuring complete tissue sample analysis during medical scanning procedures.
