Medical
insufficient expert staff to interpret the imagesremote diagnosis and computer aided diagnosis possible
ordinary X-ray machines use high dose slot scan allows low dose: 30 micro gray
at times need to repeat X-ray due to very low quality of imageshigh quality eliminates need to repeat X-ray almost completely
only one local hard copy
easy availability for quality control and research
Technical / Quality
costly: between € 2.67 - 3.21 per image
low cost: between € 0.27 - 1.26 per image
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 (can be worldwide via cellphone network / internet)
image archiving labour intensive, at times inaccurate
easy storage and instant access to archived images, worldwide automatic backup possibility
chemical waste causes environmental damage

absence of film developing / no chemicals needed
