BMDanalyse 0.2.0

About

A graphical tool used for the regional analysis of a time series of 2D medical images. This was created for the analysis of virtual x-rays, created by companion tools bonemapy and pyvXRAY from the results of a computer simulation. Intended to be used to evaluate the bone gain / loss in a number of regions of interest (ROIs) over time, typically due to bone remodelling as a result of stress shielding around an orthopaedic implant.

Written in pure Python using PyQt/PySide, pyqtgraph, numpy, matplotlib and pillow. Should work on any platform, but has only been tested on Windows.

Requirements

• Python 2.7

• PyQt >= 4.11

• pyqtgraph >= 0.9.10

• numpy >= 1.9

• matplotlib >= 1.4

• pillow >= 3.0

NOTE: All these requirements are available within the Anaconda Python distribution

Instructions for use

• Load a time series of 2D medical images (in image format such as bmp, png etc). All images should be grayscale and of the same size.

• Use the up / down arrows in the Image toolbox to place the images in chronological order. A time series of virtual X-rays is provided in the sampleMedicalImages directory.

• Create some Regions of Interest (ROIs) and run the ROI analysis tool from the Analysis toolbox. A plot will be generated showing the change in the average grayscale value with each ROI over time.

• Run the Image analysis tool from the Analysis toolbox. A contour will be displayed, showing regions of bone loss in blue and bone gain in red.
