Assumptions

  • Pixel data dominates storage size.
  • Compression is modeled as one effective ratio.
  • This calculator does not inspect actual DICOM files and stores no imaging data.

Sensitivity preview

Images / Frames -10%: Study Size 0.05 GB

Images / Frames Current: Study Size 0.05 GB

Images / Frames +10%: Study Size 0.06 GB

Formula: Stored GB = images * rows * columns * bits / 8 / 1024^3 * (1 + overhead percent / 100) / compression ratio.

About this Mammography Storage Calculator

Mammography storage varies by protocol, detector/matrix size, frame count, bit depth, compression, and DICOM metadata. This calculator makes those assumptions visible.

Who this calculator is for

  • PACS administrators planning storage.
  • Radiology IT teams sizing archive growth.
  • Imaging leaders comparing modality storage impact.

When to use it

  • Estimate Mammography storage per study.
  • Model compression and metadata overhead.
  • Feed study-size assumptions into PACS growth or cloud cost estimates.

How to use this calculator

  1. Enter image or frame count.
  2. Enter matrix dimensions and bit depth.
  3. Adjust compression and metadata overhead.
  4. Review study size in MB and GB.

Key assumptions

  • Pixel data dominates storage size.
  • Compression is modeled as one effective ratio.
  • This calculator does not inspect actual DICOM files and stores no imaging data.

Actual study sizes and compression ratios vary by protocol, scanner, anatomy, image count, reconstruction, derived objects, and local PACS/VNA policy.

Curated modality planning presets for calculator defaults; no DICOM standard text or patient data is included.

How this calculator works

Uncompressed bytes = images x rows x columns x bits per pixel / 8. Stored size = uncompressed bytes x overhead factor / compression ratio.
Stored GB = images * rows * columns * bits / 8 / 1024^3 * (1 + overhead percent / 100) / compression ratio.

Inputs explained

Images or frames

Total DICOM instances, slices, projections, or cine frames in the study.

Matrix dimensions

Pixel rows and columns for each image or frame.

Compression ratio

Effective stored-size reduction. Use 1 for no compression.

Understanding your results

Use the GB value for archive and transfer planning. Real studies may differ because of protocol variation, derived images, priors, presentation states, and vendor metadata.

Example scenarios

Mammography example

4 high-resolution mammography images at 4096 x 3328 x 16-bit with 2:1 compression is roughly 0.05 GB.

Key Features

  • Instant Calculation
  • Private & Secure
  • Mobile Optimized

Tips & Best Practices

  • Validate assumptions against recent PACS studies.
  • Run separate scenarios for high-resolution or multiphase protocols.
  • Include priors and derived images separately when sizing workflows.

Frequently Asked Questions

Does this read DICOM files?
No. It estimates storage from values you enter.
Should compression be 1 for uncompressed images?
Yes. Use 1:1 when no effective compression is expected.
Are imaging details stored?
No. Calculations run locally in the browser.
