Technical note

ETS to DCM: what to expect from the conversion

ETS is a pyramidal whole-slide image: one file carries the same scanned slide at several magnifications, and the largest level can run past 100,000 pixels on a side. DCM holds a single flat picture at one resolution. That makes the magnification the decisive choice, because there is no sensible original size to fall back on here: the full-resolution level of a slide scan is larger than most image software will open at all. DCM is lossless, so nothing further is discarded during conversion. What it cannot do is restore detail that ETS compression already removed, and the output file will usually be considerably larger.

FAQ

ETS to DCM Conversion

What are ETS files?

ETS files are used in virtual microscopy to store the full-resolution image data captured from digital slides. Commonly generated by Olympus slide scanners, ETS files work alongside VSI (Virtual Slide Image) files to enable detailed, zoomable viewing of high-resolution microscope images. An ETS file contains the raw image tiles that make up the actual slide content, allowing for fast, fluid navigation across large specimens in digital pathology and biomedical research.

What are DCM files?

A DCM file is a DICOM file, meaning it follows the Digital Imaging and Communications in Medicine (DICOM) standard for storing, transmitting, and managing medical imaging data. This standard ensures interoperability between medical imaging equipment and software, allowing images to be shared across scanners, servers, workstations, and network systems. DCM files are most commonly used in hospitals, clinics, and private medical practices that rely on medical imaging equipment such as CT, MRI, and ultrasound devices.
