A microwave super-resolution imaging approach towards breast cancer margin mapping
Harry Penketh, Sonal Saxena, Michal Mrnka +10
Accurate characterisation of margins in excised breast cancer tumours is critical to the success of surgical interventions. Yet margin status is typically confirmed post-operativel…

Imaging through scattering media by exploiting the optical memory effect: a tutorial
Harry Penketh, Jacopo Bertolotti
Scattering, especially multiple scattering, is a well known problem in imaging, ranging from astronomy to medicine. In particular it is often desirable to be able to perform non-in…
