MIDRC: DICOM viewing on iPhone and iPad. Open files, folders, supported ZIP/7z archives and direct HTTPS links. Monochrome, colour and multiframe images.
MIDRC has not undergone medical-device certification or clinical validation and is not CE-marked or FDA-cleared for diagnostic use. Non-diagnostic viewing and study only; do not use for primary diagnosis.
Provided as available, without clinical-accuracy or diagnostic-suitability guarantees. To the extent permitted by law, developers are not liable for diagnostic/treatment use; mandatory consumer rights and non-excludable liability remain unaffected. Measurements depend on DICOM calibration; without valid Pixel Spacing they use pixels. Consult a qualified physician and verify results on validated equipment before medical decisions.
De-identify imported or saved studies in three steps: Next, review frames, Done. Tags are cleaned automatically; cover embedded text with manual rectangular masks for a frame, file or compatible series. Done saves a separate DICOM copy and opens its full viewer, including measurements and MPR/3D when geometry permits. Originals stay unchanged. Inspect every frame: no automatic OCR or guarantee of anonymity. An interactive tutorial appears on first launch and after updates and can be replayed in Settings.
Copies receive a Patient N name, a daily sequence number and the date/time the copy was created. The original study date is removed.
Study library
Search by patient, ID and description, filter by modality, and save favourites and notes. Images with an existing SOP Instance UID are skipped during import.
Viewing and measurements
• Browse slices with a slider or Cine playback.
• Zoom, pan, rotate, flip and invert.
• Adjust WW/WL in real time, with numeric controls, automatic windowing and presets in every viewing mode.
• Ruler, angle, ROI, pixel values, arrows, contours, curves, CTR and text annotations.
• Editable circles defined by diameter endpoints or three edge points, with centre, diameter and ROI statistics.
• Compare two series and search DICOM metadata.
• Angles use two independent lines: points 1–2 and 3–4, with smaller and supplementary angles.
• Hold and move each point before release; edit placed handles. Visible Delete last and Delete all controls.
Planes and volumes
• Four linked views: Axial, Coronal, Sagittal and 3D. Crosshairs show other slice positions; double-tap to expand a view.
• 3D MPR: a shared point in patient coordinates, X/Y/Z translation and 360° rotation of linked planes around the centre.
• Curved MPR: define a path manually and reformat along the curve.
• MIP, MinIP and Mean for compatible series.
• Metal-based 3D Volume Rendering: bone, soft tissue, greyscale, MIP and surface modes.
• Contour-based volume clipping with undo.
Volume modes require compatible source-series geometry. Missing slices are not artificially reconstructed. Structure visibility depends on the source data and selected settings.
Export images with/without annotations, original DICOM or cleaned copies.
DICOMweb: QIDO-RS search and WADO-RS retrieval over HTTPS from a compatible server configured by the user. Configuration and authentication may be required. DIMSE is not supported. Open password-protected ZIP (ZipCrypto/AES) and 7z directly in the app. Passwords are not saved. Some archive variants are unsupported.
Available in Russian, English, German and Spanish. No registration required. Studies stay on the device; there are no ads, tracking or automatic uploads to the developer's cloud. Protect library access with Face ID or the device passcode.
