I. Script for creating a Virtual Drive from an ISO Image - using PowerShell

(Mounting and Dismounting an ISO Image)

Purpose: Creating a Virtual Drive from an ISO Image

Utility/solved issue:

• You receive physical copies (CDs/DVDs), from the hospital, containing X-Ray (Radiography) software and imagery
• One of the devices (PC/laptop) that you/your doctor need(s) to use does not have an ODD (optical disc drive)
• You or the doctor need to check the imagery
• The imagery software only works while in a non-rewrittable environment

Instructions:

1. Request from the hospital a copy of the files / gain access to a device that has an optical disc drive, insert the CD/DVD and copy the entire content to a new folder, on a USB stick (for example)
2. Use a free software like PowerISO (https://www.poweriso.com/download.htm) in order to create an ISO image from the new folder utilized in the previous step (ISO filename: "rad")
3. Download the script from here Mount_ISO.ps1 (right-click and choose "Save link as...")
4. Copy/move the script to the same directory that contains the created ISO image
5. Execute the script by right-clicking on it and choosing "Run with PowerShell"
6. Open Windows Explorer and go to This PC - alongside the Local Disk(s), a virtual drive will be shown
7. Double-click on it and review the imagery

Important

Workaround for step 5 - if the script is not executing - follow these steps:

• right-click on it and choose Properties
• at the bottom, check the Unblock box
• click Apply and then OK
• attempt to execute the script again, by right-clicking on it and choosing "Run with PowerShell"

Important

Workaround for step 7 - if a folder is shown - follow these steps:

• double-click on the folder
• locate an executable file (.exe file extension), like "DicomViewer.exe"
• double-click on it and review the imagery

Instructions - only for dismounting:

1. Open Windows Explorer and go to This PC - alongside the Local Disk(s), a virtual drive will be shown
2. Right-click on it and choose Eject

II. PowerShell script for converting video files (e.g. MKV = Matroska Video format) to a GIF (Graphics Interchange Format)

Links

• https://obsproject.com/
• https://github.com/FFmpeg/FFmpeg

Steps to follow:

1. Record the video - I recommend:
   • Software = OBS
   • Recording format (output) = Matroska Video (.mkv)
   • Muting / not recording audio (not needed)
2. Download the script: ffmpegScriptConversionMkvToGif.ps1
   • Right-click and choose "Save link as..."
   • OR
   • Click on link and press key combination CTRL + SHIFT + S
3. Move/copy the script to OBS output folder (default = "C:\Users<username>\Videos\OBS")
4. Rename desired file to input (full file name = "input1.mkv")
5. Run the script
   • From Windows/File Explorer - right-click and choose "Run with PowerShell"
   • From PowerShell CLI
     • cd to script's location

     • powershell -ExecutionPolicy Bypass -File .\ffmpegScriptConversionMkvToGif.ps1

Note

• This workflow is useful for creating DEMOs for GitHub REPOs.
  • GitHub can display several common image formats, including PNG, JPG, GIF, PSD, and SVG
  • The MKV (.mkv) file format is not officially supported as an interactive or playable format on GitHub.
• MKV = Matroska Video = a free, open-source multimedia container format that bundles video, audio, subtitle, and image tracks into a single file
• GIF = Graphics Interchange Format = a digital image file format supporting both static pictures and short, looping, silent animations, widely used on the internet for reactions and short clips
• The resulting GIF file might be bigger than the video file used as input.
