Frequently Asked Questions

PACS stands for Picture Archiving and Communication System. It is a secure medical imaging technology used by diagnostic clinics and hospitals to store, retrieve, present, and distribute electronic images and reports (such as X-rays, CT scans, MRIs, and Ultrasounds) in standard DICOM formats.

A modern PACS system for hospitals integrates directly with scanner modalities. When a scan is performed, the raw image data is sent to the PACS server, cataloged inside the database, and instantly made available on diagnostic workstation viewers. By utilizing HL7 gateways, the PACS matches scan reports directly with patient records in Electronic Medical Record (EMR) databases.

The primary difference in PACS vs RIS is the type of data they manage. PACS handles medical images and DICOM files, while RIS (Radiology Information System) handles administrative patient workflows, front-office slot scheduling, receptionist registration, and billing ledger invoicing. Syncing PACS and RIS ensures zero double-entry errors.

Cloud PACS eliminates physical hosting server racks, hardware updates, cooling bills, and dedicated IT maintenance teams. Scans are uploaded to encrypted cloud containers (like AWS/Google Cloud) and streamed directly to zero-footprint web viewers. Reports and DICOM links can also be distributed to referrers and patients instantly via automated WhatsApp/SMS modules.

A robust DICOM PACS software streamlines clinical workflows by automatically routing studies based on radiologist specialty, prioritizing STAT orders, and implementing voice dictation panels. It embeds machine learning algorithms directly in the viewing pipeline to overlay bounding box anomaly indicators, reducing diagnostic reporting turnaround times (TAT).
