Bringing critical care imaging to your patients


The SOMATOM On.site from Siemens Healthineers provides mobile head CT imaging with reliable and consistent quality right at your patient's bedside.

Change the way you care for ICU patients suffering from acute and neuro critical conditions, and transform care delivery at your hospital.


  • Minimize patient transport
  • Optimize staff deployment
  • Achieve reliable and consistent image quality at the point of care

SOMATOM Image Quality

  • The Touch UI makes scanner operation intuitive and easy.
  • Mobile CT head imaging reduces the number of ICU patient scans performed in the radiology department, potentially resulting in more streamlined utilization of stationary systems and staff.

All-in-one system design

  • Integrated computers allow flexibility for patient scans in small spaces where additional equipment would be a hindrance.
  • Slim and easy system with a built-in trolley & batteries. 
  • Integrated patient support accessories.

Smart driving concept

  • The motorized trolley with an ergonomic drive handle allows easy maneuvering to the patient’s bedside. 
  • The integrated camera provides the user real-time viewing on the Touch UI. 
  • Slow and fast drive modes for system transport and maneuvering.

Convenient patient positioning

  •  Integrated patient support accessories include patient scan support (head holder for neuroimaging) and body support (shoulder board for neuro imaging)
  • No need for bed adapters or special connectors to address individual patient bed design
  • Telescopic scanner design allows the gantry to glide away from the patient, offering ample space for patient positioning until you are ready to start scanning
  • 35 cm gantry bore opening

Easy scan set-up and fast workflow

  • Intuitive Touch UI
  • GO technologies provide guidance for cross-trained staff through the scanning process
  • Recon&GO performs automated postprocessing and automatically uploads the images to PACS
  • Single-operator design

Telescopic scanner design

  • SOMATOM On.site features a telescopic gantry that glides on the stationary system trolley base during the scanning process.
  • The telescopic gantry contributes to consistent and reliable CT image quality: the trolley remains stationary during the image acquisition, reducing motion artifacts typically caused by scanner movement.

Self-shielded system design

  • Attachable radiation shields cover the front and back gantry openings.
  • The telescopic gantry houses the moving scanner components, with the tube and detector moving away from the patient or the front gantry. This innovative approach reduces scatter radiation compared to conventional mobile CT scanners that don’t deploy this design.
