SUMMARY:Semper Citius: Towards Dynamic Photoacoustic Imaging - Marta Betck
 e\, UCL
DTSTART:20171201T140000Z

CONTACT:Rachel Furner
DESCRIPTION:In photoacoustic imaging\, as in many high resolution modaliti
 es\, the major bottle neck is the acquisition time of finely spatially sam
 pled data. In particular for imaging of dynamical processes\, this results
  in incomplete data. In this talk I am going to review the journey towards
  dynamic photoacoustic imaging we embarked on in our group at UCL. I will 
 consider fast numerical models for wave propagation for the implementation
  of the forward and the adjoint operators. I will describe different appro
 aches to reconstruction from compressed or subsampled data for acceleratio
 n of a static image reconstruction and finally I will discuss fully dynami
 c image reconstruction using spatio-temporal regularisation within the var
 iational framework.\n\nJoint work with Simon Arridge\, Andreas Hauptmann\,
  Felix Lucka\, Bolin Pan\, Kiko Rullan from Inverse Problems group at UCL 
 and Paul Beard\, Ben Cox\, Nam Huynh\, Bradley Treeby\, Edward Zhang from 
 Photoacoustic Imaging Group at UCL\n\n
