Scientific image detailing ghost repelled Mrs Leadbetter (11)
I believe the answer is:
spectrogram
'scientific image' is the definition.
'spectrogram' can be an answer for 'image' (spectrogram is a kind of image). I'm not sure about the 'scientific' bit.
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for spectrogram that I've seen before include "Colourful pic" , "colourful image" .)
