Imaging Tools

Essential utilities for DICOM image processing — ROI statistics, histograms, line profiles, HU conversion, and segmentation.

Utility Suite.

QAF Tools provides the fundamental image processing operations needed for day-to-day work with spectral CT data. Each tool operates on raw or HU-converted DICOM images with full multi-energy bin support.

How It Works.

Upload a DICOM folder, browse slices and energy bins, then run any tool. Results appear as interactive plots with export to Excel, PNG, or converted DICOM downloads.

Available Tools.

Everything you need for DICOM image analysis

HU Conversion

Convert raw attenuation values to standardized Hounsfield Units using air/water calibration. Download converted DICOM or PNG.

ROI Analysis

Draw circular or rectangular ROIs to calculate mean, std, min, max, and other statistics across all energy bins.

Histogram Analysis

Generate pixel intensity histograms for selected ROIs. Single-image or averaged across all slices, with configurable bin count.

Line Profile

Draw lines on images to extract intensity profiles. Analyze edges, gradients, and spatial variations with adjustable line width.

Segmentation

Threshold-based image segmentation for isolating structures. Download segmented images for further analysis.

Data Export

Export any analysis result to Excel or CSV. Download converted DICOM files and publication-quality PNG plots.

How to Use.

Three simple steps from upload to export

Upload DICOM Files

Select a folder of DICOM images. Multi-energy bin data is detected automatically.

Run Your Analysis

Draw ROIs, draw lines, or adjust settings. Interactive tools give instant visual feedback.

Export Results

Download plots, Excel data, or converted DICOM files. Everything you need for your paper.

Supported Formats

Input: DICOM (.dcm), multi-energy spectral CT
Output: Excel (.xlsx), CSV, PNG plots, converted DICOM
