The goal is • To list dose reducing methods in an Interventional Radiology (IR) system • To demonstrate simple steps that should be taken routinely • To display advanced methods and warnings systems available  

A. Introduction: A key radiation safety principle is ‘As Low As Reasonably Achievable (ALARA)’. We categorize and remind the viewers on steps they could take to reduce patient dose in an IR system. B. X-ray source-detector 1. Pulsed fluoroscopy 2. Low dose Fluoroscopy 3. Collimation and filters 4. Last image hold and cine Loops 5. Low dose/faster C-arm cone-beam CT (CBCT) 6. Reduced slab CBCT C. Patient positioning 1. Maximize distance between X-ray tube and patient 2. Minimize distance between patient and detector 3. Reduce exposing same skin area 4. Reduce oblique projections 5. Re-positioning using last image hold D. Image guidance 1. Road-map 2. Reference image fade 3. CBCT 3D display 4. Live 2D display over 3D anatomy 5. Live 3D scheme display over 2D image E. Dose reduction 1. Live skin entrance dose (SED) display 2. Dose threshold warning bell 3. Live graphical 3D SED tracking 4. Introspect high-dose events F. Cases G. Summary: This exhibit reminds viewers to be conscious of radiation dose reduction by taking simple steps and utilizing advanced tools.
