CRYSM

Installation

In order to install the package, run

uv tool install -e .

This exposes the crysm command. To see available commands, run crysm --help. The commands correspond to the decorated functions in src/main.py.

Installation of uv

In this package, uv is used for package management. To install on linux/mac, run

curl -LsSf https://astral.sh/uv/install.sh | sh

and on windows (in powershell)

powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"

Usage

The functionality of this library can be found by typing crysm --help or reading the functions in src/main.py. Below are some examples.

Example 1: Finding correction factors for the central cross from a flatfield image

crysm find-center-cross-correction 24bit/flatfield_200kV_24bit.mib
> For image: 24bit/flatfield_200kV_24bit.mib:
>   Mean value of cross: 40151.59
>   Mean value of central four pixels: 74076.75
>   Mean value of rest of image: 18284.44
> Suggested arguments for correction:
>  --additional-pixels 4 --correction-factor 2.196 --central-four-factor 4.051
> Number of additional pixels should be verified with detector manufacturer

This command can also take multiple images, but they should be collected with the same parameters (unlike the example below):

crysm find-center-cross-correction 24bit/flatfield_200kV_24bit.mib 12bit/flatfield_200kV_12bit.mib 6bit/flatfield_200kV_6bit.mib                                          3.11   17:08:04

>   Mean value of central four pixels: 63.00
>   Mean value of rest of image: 18.22
>   Additional pixels: 4
>   Correction factor: 2.194
>   Central four factor: 3.457
> Suggested arguments for correction:
>  --additional-pixels 4 --correction-factor 2.195 --central-four-factor 3.854
> Number of additional pixels should be verified with detector manufacturer

Example 2: Correcting the central cross of a calibration image

crysm pets-correct-center-cross-calibration --additional-pixels 4 --correction-factor 2.196 --central-four-factor 4.051 SAED_150cm.mib WIDE_150cm.tiff
> Wrote corrected image to WIDE_150cm.tiff

Example 3: Correcting the central cross of a pets project

crysm pets-correct-center-cross --additional-pixels 4 --correction-factor 2.196 --central-four-factor 4.051
