A device ( 1 ) for use in imaging a subject using both light and gamma rays emanating from the subject, the device including: a first sensor means ( 2 ) responsive to light received thereby from the subject to generate first signals ( 6 ) for use in forming a first image ( 10 ) of the subject; a second sensor means ( 3 ) responsive to gamma rays received thereby from the subject to generate second signals ( 7 ) for use in forming a second image ( 11 ) of the subject and arranged to receive gamma rays from the subject which have passed from the subject through the first sensor means before reaching the second sensor means.
