Radiology Viewer — PDF Sentry

In-Browser DICOM Viewer

Drop in individual DICOM files or a full ZIP study and review images instantly — organized by study and series, with the patient and acquisition metadata alongside.

Window / Level & Zoom

Adjust window width and center to bring out soft tissue, bone, or lung detail. Zoom in 5% steps, pan, and reset to fit — all with keyboard and mouse-wheel shortcuts.

Multi-Frame Cine

Play multi-frame ultrasound and other cine series frame by frame or in continuous playback, then step to the exact frame you want to capture.

Measurement Tools

Length, angle, ellipse, and rectangle measurements drawn directly on the image — so a finding can be quantified, not just pointed at.

Markup & Annotation

Arrows, freehand, and text markup in adjustable colors and line weights. Erase and refine until the image reads clearly for a non-clinical audience.

Exhibit & Findings Builder

Promote any annotated frame to a captioned exhibit, or assemble a structured findings document — reorder, caption, and export into the case file.
