Table 2.

Measured relative HW phases for the mono-surface array loaded with the pig body phantom, relative optimized phases (PV1 and PV2), and the required coaxial cable PSs required to validate the optimal vectors PV1 and PV2. The coaxial cable PSs were computed after subtracting the HW phases from PV1 and PV2, subtraction the results from the maximum positive phase value and finally rounding the resulted phase nearest to 22.5°.
