hello all ndt fellows..i am a student from india preparing a seminar on 'TOFD-advantages,limitaions and applications'.i have a few doubts in my mind abt this technique ..so please help me clear those doubts....

1.where can i get tofd instrument in india...cost?
2.sorry but i dont really get what difference does it make whether it is reflection or diffraction?.
3.if there are 2 defects one above the other....doesn't the wave get diffracted twice?....in that case what is the result?......
4.why does diffraction take place at the tips only?..
5.what is the smallest defect that can be detected?
6.what type of defects can be detected?....

i am a complete novice to ndt ..so plz excuse me...if u know the answers do email me as soon as possible...
