Introduction 

 

Consideration on deployment 

The Delft Light is a portable X-ray system which can be deployed in almost any 
venue, room or even a tent. Local radiation safety rules need to be followed to 
obtain high quality images with the least amount of radiation (ALARA principle). 

Because of its nature there is 

no ‘standard’ setup for the 

Delft Light while this always 

depend on the venue used, amount of space, patient flow etc. Some considerations 
for a correct use are: 

 

Patient flow, where do patients enter/exit the room? 

 

X-ray beam direction. Where does the primary beam point to? This maybe a 
trade off with the patient flow. 

 

Radiographer area. What is a safe distance for the radiographer, additional 
lead shielding available? 

 

What is the maximum distance between the X-ray and detector stand? 
Minimum distance should be at least 120 cm. 
 
 

Notice for save operations 

The Delft Light is a fully 

battery-operated X-ray system

. Annex A provides detailed 

information on the correct use and storage. Some important considerations: 

Battery (X-ray/detector) 

 

Always store the batteries is a save location (the backpack) when not in use. 

 

Always check the batteries on mechanical damage and or leakage before 
use.  

 

Never use a battery with apparent mechanical damage and/or leakage 

 

Always use the delivered battery chargers and power cords. 

 

When the Delft Light is not in use for a longer period recharge the batteries at 
least every 5 months. 

ATXtreme (X-ray) 

 

Although the Delft Light is a portable system the X-ray generator and tube 
weigh 8 kg. Take special care when mounting the X-ray part to the provided 
stand. 

 

Always use the fall save mechanism attached to the stand to prevent the X-
ray tube from dropping when adjusting the system to the required height. 

Flat panel detector 

 

Always use the fall save mechanism attached to the stand to prevent the 
detector from dropping when adjusting the system to the required height. 

 

Always use the provided detector holder to prevent damage to the image 
sensor.
