Protocol Structure

00_CarotidAngioRoutine (Adult)

  • Topogram (AP)
  • Premonitoring
  • Monitoring
  • Contrast (Carotid Angio)

Patient Orientation Registry in System

  • Set the orientation patient in system : Head First – Supine

Topogram

  • Position the patient in head first supine position.
  • Placed the patient’s head inside the head holder and properly strap the head and chin.
  • Align the patient in Mid-Sagittal plane of the table.
  • Position the transverse laser light beam above glabella to start the topogram.
Topogram Lateral of CTA Carotid

Topogram Parameters

Topogram (AP)

  • Topogram length: 512 cm
  • Slice: 0.6 mm
  • Scanning direction: Craniocoudal

Topogram (Lateral)

  • Topogram length: 256 cm
  • Slice: 0.6 mm
  • Scanning direction: Craniocoudal
  • Tube position: Lateral
  • Stop the topogram scanning when the scanning reach / pass over the base of skull

Pre-Monitoring / Contrast Trigger

  • Activate the topogram image.
  • Place the scan planning line at the level of aortic arch.
