Siemens Healthineers

Siemens Healthineers, based in Erlangen, makes the Biograph Vision Quadra total-body PET scanner and the NAEOTOM Alpha photon-counting CT, alongside MAGNETOM MRI, and it owns the radiotherapy company Varian. Nuclide links it to PET/CT, CT and MRI as technologies, to nuclear medicine and total-body PET hardware, total-body PET for screening and ultra-low-dose imaging, AI auto-contouring and medical cyclotrons, and to ideas on total-body PET for personalised radioligand dosing and on validating and reimbursing AI contouring to expand radiotherapy capacity. Owning both imaging and radiotherapy gives it a position across the treatment pathway that few rivals share. Whether total-body PET moves from research instrument to routine clinical tool is the open question. Varian has its own page.
