qPACS

The viewer

Diagnostic imaging. Without leaving the browser.

Radiologists open a study in Chrome, Edge, Firefox or Safari and have the tools of a reading station in front of them — on a reporting workstation, a ward PC or a laptop on call, with nothing installed on any of them.

  • No client install
  • No plug-ins, no Java
  • WebGL2 for 3D where available
  • 90+ tools

The viewer, on real studies

Every capture below is the shipping viewer reading an archived study — no mock-ups, no compositing.

The qPACS worklist.

The qPACS worklist. Studies appear here seconds after acquisition, matched to their order by accession number, with patient, visit, modality, series and image counts — and drag-and-drop upload for anything arriving outside DICOM.

The toolset

Everything a reading station has

Grouped the way a radiologist reaches for them, not the way they are implemented.

Image manipulation

  • Window / level — brightness & contrast
  • Window presets — lung, bone, brain, soft tissue, abdomen
  • Zoom, pan and scroll / stack navigation
  • Fit to window, actual size 1:1, reset view
  • Rotate left / right 90°, flip horizontal / vertical
  • Invert greyscale
  • Magnifier

Measurement & annotation

  • Length, angle and Cobb angle
  • Rectangle and ellipse ROI — mean, min, max, area
  • Freehand ROI
  • Probe — pixel value / CT Hounsfield units
  • Arrow marker and text annotation
  • Freehand drawing
  • Eraser, delete annotation, clear all

Navigation & layout

  • Cine playback with adjustable speed (FPS)
  • Previous / next image and previous / next series
  • Series thumbnail browser
  • Layouts — 1×1, 1×2, 2×2, 3×3
  • Full screen and maximise viewport
  • Viewport synchronisation
  • Crosshair and reference lines

Display & output

  • Image overlay — patient / image data
  • DICOM tag inspector
  • Key image marking
  • Snapshot and print
  • Export image — PNG / JPEG
  • Download DICOM — permission-gated
  • Web upload — files, folder or .zip

Advanced visualisation

  • qLens™ — local enhancement lens
  • MPR — axial, coronal, sagittal
  • Linked crosshair across planes
  • Per-plane scrolling
  • MIP / MinIP — maximum / minimum intensity
  • Average thick-slab projection
  • 3D volume rendering — orbit and zoom

Performance & personalisation

  • Progressive image loading and slice prefetch
  • Secure caching
  • Large CT / MR study handling
  • Server-side decoding on retrieve
  • Keyboard shortcuts
  • Configurable mouse bindings
  • User preferences — layout, overlays
  • Hanging protocols

Innovation

qLens™ — enhancement that never touches the study.

Edge enhancement, adaptive contrast and denoise applied inside the lens region only. The surrounding image stays exactly as acquired, and the source pixels are never modified.

Why it matters clinically

  • The source DICOM pixel data is never modified — enhancement is display-only and reversible
  • One-click reset returns the image to its acquired presentation
  • The viewer indicates clearly when post-processing is active
  • No export, no second dataset, no version of the study to reconcile later

Volume rendering

MPR, MIP and 3D in the same session

Advanced visualisation is normally a separate purchase: another workstation, another licence, another queue, and a study that has to be exported to reach it. In qPACS it is part of the same browser tab the study is already open in.

MPR 2×2 layout with a linked crosshair
MPR. Axial, coronal and sagittal reconstructed from one CT series in a 2×2 layout, with a linked crosshair across planes and per-plane scrolling at W 400 / L 40.
3D volume render with orbit and zoom
3D volume rendering. DVR and thick-slab from the archived study, rotated and zoomed in the browser — no export, no rendering workstation and no extra licence.

Engineered for the read, not for the demo

  • Compressed studies are decoded server-side — the browser stays light
  • Slices stream progressively so the first image is up immediately
  • Large CT and MR series scroll without stalling
  • The same interface on every PC in the building

Image handling

  • Multi-frame DICOM
  • Ultrasound RGB/YBR colour and cine loops
  • MONOCHROME1 / MONOCHROME2
  • Compressed transfer syntaxes — transcoded on retrieve
  • Rescale slope / intercept and modality LUT

qPACS Mobile — Android & iOS

  • Study worklist with paging and instant search
  • Search by patient name, ID/MRN, accession, modality or date
  • Opens studies in the qPACS viewer, with the same tools and presets
  • Signs in with the same PACS account, role and permissions
  • No images, reports or patient data stored on the device
  • Connects to your server by address — no cloud routing
  • Phone and tablet, portrait or landscape
