I'm about to start my next semester at university, I've brought the books and thought I'll make a head start on going through them.
I'm currently working through chapter 1 of
The Physics and Technology of Diagnostic Ultrasound at the end of the chapter there are a set of question, I've worked through all and managed to work out the formulas for the answers.
1 question in particular which reads:
An Ultrasound machine has a dynamic range (defined as ratio of the largest echo to the smallest echo) of 1,380,000. What is the dynamic range expressed in dB?
now the answer they have written is 61.4 dB - I'm trying to find / workout the formula which is used to determine this, now after googling this question I stumbled upon what is db noise floor dynamic range
Which gave me some idea, but even confused me a little, so I'm here today to see if someone could help me understand the answer / what formula was used to get to the given answer in better context.
