EMV for Macintosh

Escape Medical Viewer (EMV) 4.4x is an elegant, robust and lightweight DICOM viewer, anonymizer and converter. A MacOS X native 64-bit application written from scratch using Cocoa, EMV 4.4x:

  • opens DICOM images (stand-alone or DICOM CDs and DVDs);
  • facilitates geometry and color manipulation;
  • has handy tools for defining ROIs and performing calibrated measurements;
  • removes sensitive information from pixels and DICOM data (anonymize);
  • exports to a variety of modern still-image and movie formats;
  • has a beautiful, intuitive, user-centric interface, that works the way you expect.

At a glance


  • 64-bit application: increased robustness and compatibility with new Macs and OS versions.
  • Moved from QuickTime (used in EMV since 2001) to DCMTK, a popular DICOM Toolkit
  • Full-screen viewing and multi-monitor support
  • Printing to any connected system printer


  • Multi-series display of up to 4 sequences or clips in a selection of predefined arrangements ("hanging").
  • Multiframe display (series, clips, sequences) in user-defined grid.
  • User-controlled display of demographics and DICOM overlays.
  • Extraction of localizers if found in the same series as the slices (to enable usage in multi-series display)
  • Automatic display of reference lines when more series of the same frame of reference are displayed simultaneously
  • Alternative colorizations of grayscale and color images.
  • Handling of non-square pixels.
  • Calibration: define the real-world size of pixels.
  • User-controlled action scope: act on the current frame or on the entire sequence.
  • User-controlled marking: allow for selective traversing, anonymizing and exporting.
  • Cine with autoplay, traverse, user-defined frame rate, and time-vector support.
  • DICOM data browser

User objects and measurements

  • User objects: measurements, textual annotations, arrows
  • Eraser: turn any rectangle into an eraser to remove burnt-in information (commonly used with ultrasound clips).
  • Density measurement in Hounsfield units, where applicable.
  • Calibrated US measurements when ultrasound regions are defined.

Batch conversions

  • Export towards images or movies: frame, sequence, series, study, patient, all patients, marked items.
  • Anonymize: file, sequence, series, study, patient, all patients, marked files.
  • Export DICOM data: file, sequence, series, study, patient, all patients, marked files.
