I am giving you an Answer but still not sure if this is right !

Phased array system:

Phased array system consists of many elements which are pulsed sequentially at different time intervals and hence this avoiding the usage of different angle Probes.In Phased array system the the 64 channels are integrated in a single casing hence only one probe is used.

In TOFD system is mainly designed to overcome the difficulties and complications faced in the Radiographic testing.In TOFD system there are different channels with a separate Transmitter and Receiver.The number of channels is directly Propotional to the thickness and hence more the number of channels,more thickness the waves can travel.
