A telephone conference (14 th of December) with the four of us in order to discuss the following issues: - identify the subjects to be covered in the report - finalize the list of candidates that will be asked to join the working group Here we should use as criteria: expert in (innovative) techniques and good overview of what happens worldwide in this field (After our first telephone meeting, the candidates have been contacted by the conveners.) Recommendation from the liaisons: Find a good balance between reporting about the past achievements on impact on nuclear physics in medicine, the new developments in the pipeline of being implemented in a clinical environment and future ideas. Medical imaging WG NuPECC Liaisons: Faiçal Azaiez (Orsay), Alex Murphy (Edinburgh) Conveners : José Manuel Udias (Madrid) and David Brasse (Strasbourg)

February 20, 14h : First video conference. From the liaisons: The number of pages dedicated to medical imaging part should be between 30 and 40 (figures included). Time line: - draft of the booklet ready by October Final version approved by NuPECC in its March 2014 meeting - Printed volume ready in June 2014 and distributed

The list of members becomes: Piergiorgio Cerello (Torino)GRID approach Jozsef Molnar (Debrecen) Helen Boston (Liverpool)detectors Jürgen Gerl (GSI)detector Bo Cederwall (Stockholm)detector Ian Lazarus (Daresbury)Electronics, data acquisition Alberto Del Guerra (Pisa)TOF PET, PET/MR… Magdalena Rafecas (Valencia)simulation and reconstruction algorithm José Maria Benlloch (Valencia) Peter Dendooven (KVI) Katia Parodi (München)Imaging in therapy Wolfgang Enghardt (Rossendorf)Imaging in therapy Frank Verhaegen (MAASTRO)hadrontherapy, modeling, simulation Christopher Scheidenberger mass spectrometry Yves Charonnuclear imaging

First part: State of the art 1- Time-of-flight PET (P Lecoq, I Lazarus, P cerello, P Dendooven...) 2- PET/MRI 3- Preclinical instrumentation (A Del Guerra, M Rafecas, I lazarus...) Second part: prospects/challenges 1- New challenges in multimodality imaging (I Lazarus...) 2- New challenges in detector design (A Del Guerra, M Rafecas, P lecoq, P Cerello, I Lazarus...) 3- DAQ system and reconstruction strategies (M Rafecas, I Lazarus, M Priegnitz, F Fiedler, C Scheidenberger, P Cerello...) 4- Photon counting: towards spectral CT 5- Interface between medical imaging and hadrontherapy (A del Guerra, M Rafecas, P Cerello, P Dendooven, P Thirolf, K Parodi, M Priegnitz, F Fiedler...) 6- Interface between medical imaging and spectroscopy (C Scheidenberger) 7- Implication of our community in medical imaging education Two different parts have been proposed. 1-The first one focuses on what our community helped to achieve in medical imaging field during the previous years (for example case studies in oncology?). 2-The second part is dedicated to future applications and should be based on the fact that most of the large leaps forward in nuclear imaging capabilities are clearly linked to technological break through.

During the meeting, it was mentioned that training into most medial imaging technical topics is done very often inside groups participating in nuclear physics experiments. We should elaborate on this too, probably in collaboration with the other groups. There are interfaces between WG’s that has to be organized
