Teleradiology installation between the Radiology Departments of the Main Hospital Compound and the Paimio Hospital, both belonging to the Turku University Central Hospital has been in clinical use since August 1991. It is based on Unix workstations with 1280 × 1024 pixel display with 216 shades of gray. It has been used to receive previous chest images from Paimio to be compared with recent films taken at TUCH Emergency Department. Scanning resolution of 1024 × 1024 pixels seems to be enough for reference images and probably sufficient for most other purposes.
