Key differences analog vs digital radiography Print


X-ray Characteristics
Analog (film) CR (phosphor) DR (direct)
Computer aided detection for TB no no yes
Low dose - high image quality no yes/no yes
Images per hour 30 30 60
Image cost (per throughput) € 2.50 - 3.50 € 0.60 - 1.55 € 0.30 - 1.50
Immediate image availability no no yes
Image transfer over mobile phone network no no yes
Data management tools no yes yes
Consumables elimination
no no yes


Analog X-ray

Direct Digital X-ray

insufficient expert staff to interpret images teleradiology and computer aided detection possible
ordinary X-ray machines use high dose new flat panel detectors allow low dose
need to repeat X-ray due to low quality of images constant quality as Automatic Exposure Control s/w eliminates need to repeat X-ray
only one local hard copy
easy availability also in the Cloud for quality control and research
Technical / Quality
cost between € 2.50 - € 3.50 per image cost: € 0.30 - € 1.50 per image (depending on daily throughput including depreciation and maintenance)
poor image or viewer quality consistent high quality image
poor film development causes useless images
no developing needed
delay between X-ray exposure and image availability
image immediately available (also via mobile phone network / internet)
image archiving labour intensive, at times inaccurate
easy storage and instant access to archived images, automatic backup possibility
chemical waste causes environmental damage

clean technology, no film no chemicals needed; can operate on batteries and solar power
