About formats

DCM is the file extension for the DICOM (Digital Imaging and Communications in Medicine) standard, a comprehensive framework for handling, storing, transmitting, and printing medical imaging data. Developed jointly by the American College of Radiology (ACR) and the National Electrical Manufacturers Association (NEMA), the standard reached its current form as DICOM 3.0 in 1993 and has been continuously updated since. A DCM file is much more than an image container: it encapsulates the pixel data alongside a rich set of structured metadata tags organized into groups that describe the patient (name, ID, birth date), the study (date, referring physician, description), the imaging series (modality, body part, patient position), and the specific image (acquisition parameters, pixel spacing, window/level settings). DICOM supports a wide range of pixel data types — monochrome (8, 12, or 16 bits), RGB color, YBR color spaces, and multi-frame sequences for cine loops or volumetric stacks — with optional JPEG, JPEG 2000, JPEG-LS, or RLE compression. One advantage is clinical interoperability: every modern medical imaging device — CT, MRI, X-ray, ultrasound, PET, mammography — produces DICOM output, and every PACS (Picture Archiving and Communication System) ingests it, making DICOM the universal language of radiology. The embedded clinical context is another crucial strength: unlike generic image formats, each DCM file carries the metadata needed to correctly display, measure, and interpret the image in a diagnostic setting.

RB is the native ebook format of the Rocket eBook, one of the first commercially available dedicated e-reading devices, developed by NuvoMedia and released in October 1998. Founded by Martin Eberhard and Marc Tarpenning — who later co-founded Tesla Motors — NuvoMedia designed the Rocket eBook as a handheld device with a reflective LCD screen, capable of storing approximately ten books in its internal memory. The RB format packages HTML-based content along with embedded images, metadata, and a table of contents into a single binary container optimized for the device's limited hardware. Content was purchased and downloaded through NuvoMedia's RocketLibrarian desktop software. A notable advantage of the format was its early support for bookmarking, annotation, dictionary lookups, and adjustable font sizing — features now standard on modern e-readers but revolutionary in the late 1990s. The Rocket eBook demonstrated viable commercial demand for dedicated reading devices, paving the way for subsequent platforms from Sony, Amazon, and others. NuvoMedia was acquired by Gemstar-TV Guide International in 2000, which discontinued the device line in 2003. While RB files are largely a historical curiosity today, they can be converted to modern formats using ebook management tools, and the format remains significant as a pioneering chapter in the evolution of digital reading.

Frequently Asked Questions

Why convert DCM to RB?

DICOM metadata is complex — converting to RB extracts just the visual data when full DICOM context is not needed.

What programs open RB files?

Calibre and legacy RocketEdition/REB1100 devices open RB format e-books

Can I batch convert multiple DCM files to RB?

Upload several DCM files at once. Each one converts to RB independently — download them individually or together when all are done.

What platforms support the DCM to RB converter?

Any device with a web browser — Windows, macOS, Linux, Chrome OS, iOS, and Android. No app installation is needed.

Are uploaded DCM files stored permanently?

No. Source files are deleted immediately after processing, and converted outputs are purged from servers within 24 hours automatically.

Are colors preserved in the DCM to RB conversion?

Color information transfers accurately to RB. The converter maintains the original color profile as closely as the target format allows.
