Read full description

IO DICOM Tools is a professional DICOM troubleshooting toolkit for imaging engineers, PACS administrators, and clinical informaticists. Import, browse, validate, view, and exchange medical images — all from your iPhone or iPad, with no server required. Data Browser Browse your imported DICOM library organized by study, series, and instance. Inspect every DICOM tag with human-readable names, dictionary lookups, and inline structural issue highlights. Metadata sheets summarize problems at a glance and let you drill straight into the Validator with a single tap. Send selected content to a remote destination via C-STORE with per-instance progress tracking. DICOM Validator Deep, multi-pass file validation that goes far beyond a simple tag dump: Structural byte-walk verifies every declared tag length against the actual file stream VR format checks validate each tag's value against DICOM PS3.5 character-set and length rules Required-tag checks confirm that type-1 UIDs and key pixel-data attributes are present and non-empty Pixel-module consistency checks catch photometric interpretation mismatches and bit-depth conflicts A lightweight frame-0 render probe detects decode failures before they surprise you in a viewer Non-fatal metadata parse diagnostics expose malformed or private tags that other tools silently ignore Launch Validator from the Data Browser, a Metadata sheet, a Viewer failure, or open any .dcm file directly from Files. Each finding includes the exact DICOM tag, tag group, and current value so you can pinpoint and describe the problem to a vendor immediately. Copy a plain-text findings summary for escalation or ticket filing with one tap. DICOM Image Viewer Full-window diagnostic viewer with pinch-to-zoom, pan, rotation, flip, and adjustable Window/Level. Structured failure summaries describe exactly why a file fails to render — pixel data issues, unsupported transfer syntaxes, and codec errors are all surfaced with actionable detail. Escalate directly from a viewer failure into the Validator for a full findings report. Network Destinations & DICOM Connectivity Configure remote AE destinations and run the full suite of DICOM network operations: C-ECHO — verify connectivity to any DICOM node in one tap C-FIND — query at Study, Series, or Instance level with flexible filters (patient name, ID, accession number, study date, modality, UID) Modality Worklist (MWL) — query scheduled procedures by patient, modality, station AE, or date C-GET — retrieve studies directly to your on-device datastore; received files are indexed automatically and appear in the Data Browser without a manual rescan C-MOVE — initiate study and series moves to a configured destination AE Activity Log & Protocol Inspector Every DICOM network session is captured as a structured timeline — association negotiation, DIMSE request/response steps, and association release or abort in a single card. Drill into each session for: Per-step structured detail fields Command-exchange summary grouped by DIMSE message ID Raw PDU hex dumps including P-DATA-TF fragment breakdowns Command-set field decoding (Command Field, Message ID, Command Data Set Type, Status) Multi-fragment PDV reassembly for both command and dataset payloads Session-scoped copyable trace export for escalation to vendors or support teams Local Storage SCP Run a DICOM Storage SCP directly on-device with a configurable AE title and port. Start and stop the SCP from within the app and receive C-STORE objects from any networked DICOM node. Subscription Full access requires an annual subscription with a 7-day free trial. After the trial, the subscription auto-renews at the listed price unless cancelled at least 24 hours before the renewal date. Manage or cancel anytime in your Apple ID account settings.
