About this activity
What to expect
A working session on 4D CT for radiation therapy simulation. Participants acquire, sort and review a phantom dataset, then look at three clinical cases where breathing artefacts changed the plan.

Your host
DK
Daniel Kim RT(R)(CT) · Senior Applications Specialist, Computed Tomography
Cardiac CT protocols, photon counting, dose optimisation
Daniel runs the live CT scanning sessions at the booth. He is the person who will rewrite your protocol with you on the spot.
Your host
HW
Dr. Hannah Weiss MD · Global Medical Affairs, Pharmaceutical Diagnostics
Cardiac PET tracers, amyloid imaging, contrast agents
Hannah leads medical affairs for our diagnostic agents. She chairs the breakfast panels where early adopters talk about what changed in their practice.
Your host
KA
Kwame Asante MBA · Director, Imaging Digital Solutions
Care orchestration, imaging workflow, health-system integration
Kwame ran imaging operations for a five-hospital system before joining GE HealthCare. He demonstrates the command-centre work with the numbers from a real department rather than a slide.
Your host
SL
Dr. Sofia Lindqvist MD, PhD · Clinical Lead, Oncology Solutions
Radiation oncology, adaptive planning, motion management
Sofia is a radiation oncologist working on plan adaptation. Her learning labs walk a case from simulation to the fraction where the plan had to change.
Your host
EV
Dr. Elena Varga PhD · Principal Scientist, Magnetic Resonance
Deep-learning reconstruction, high-performance gradients, neuro MR
Elena works on the reconstruction side of MR. Her protocol workshops start from the exam you want to shorten and work backwards to the sequence that lets you.
Your host
TR
Thomas Reinhardt MSc · Product Marketing Director, Interventional
Structural heart, electrophysiology labs, image-guided systems
Thomas has spent his career beside interventional tables, first as an applications engineer and now shaping the systems. He runs our lab-design conversations at every show.
Your host
PR
Dr. Priya Raghunathan MD · Medical Director, Women's Health
Mammography, contrast-enhanced mammography, breast ultrasound
Priya is a breast radiologist who joined us to work on patient experience as seriously as image quality. She leads the women's health hands-on sessions.
Your host
RM
Dr. Rajiv Menon MD, PhD · Global Clinical Leader, Molecular Imaging
PET/CT, theranostics, quantitative imaging
Rajiv has spent two decades on molecular imaging, from tracer development to the scanners that read them. He runs our theranostics briefings and is happiest with a case list and a whiteboard.
Your host
ML
Maria Lopez RDCS, RVT · Senior Clinical Applications Specialist, Ultrasound
Cardiovascular ultrasound, strain imaging, 4D echo
Maria teaches the hands-on ultrasound sessions. She scanned in a busy echo lab for eight years and builds every workshop around the studies people actually do on a Monday morning.
Your host
AO
Dr. Amara Okonkwo MD, FACC · Chief Medical Officer, Cardiology
Cardiac CT, coronary artery disease, PET myocardial perfusion
Amara leads the clinical team behind our cardiology portfolio. She practised interventional cardiology for eleven years before moving to industry, and still reads studies most weeks. At our events she is the person to ask what a new tracer or reconstruction actually changes in the clinic.
