PACS implementation stages

Stage 1	Mini-PACS system with linked workstations
Stage 2	Open-source archive with webserver/viewer or mini-PACS system with cloud-based PACS storage
Stage 3	Full PACS platform with enterprise VNA or local PACS storage

Note: These stages of implementation represent progressive levels of technical complexity that factor in site infrastructure, hardware constraints, study volume, available personnel and clinical use. Each stage has varying implementation requirements that are minimal at stage 1 and most comprehensive at stage 3. VNA = vendor-neutral archive.
