💖 phm2pj — bestie edition 💖

okay so this is phm2pj(1), a manual page from the Engineering section, and it's literally the glow-up tool for turning a phantom object into projections. sit down, grab a boba, we're doing science 🧚✨

✨ NAME ✨

phm2pj — calculate projections through a phantom object. that's it, that's the whole job, and she does it flawlessly 💅

🌸 SYNOPSIS 🌸

phm2pj outfile ndet nview [--phantom phantom-name] [--phmfile filename]
[OPTIONS]

🦋 DESCRIPTION 🦋

so phm2pj calculates projections through a phantom object. and where does that phantom come from, you ask? bestie, you've got two options and both are valid: either a predefined --phantom, or a --phmfile. pick your fighter 🫶

💅 OPTIONS 💅

• --outfile — the name of the output file for the projections. this is where the good stuff goes.
• --ndet — number of detectors. count 'em.
• --nview — number of rotated views. also count 'em.
• --phantom — the predefined phantom to use for projection. can be one of:
  • herman — Herman head phantom 🧠
  • herman-b — Herman head phantom (Bordered)
  • shepp-logan — Shepp-Logan head phantom 👑
  • shepp-logan-b — Shepp-Logan head phantom (Bordered)
  • unitpulse — Unit pulse phantom ⚡
• --phmfile name — get the phantom from a phantom file. DIY energy fr fr.
• --desc — description of raysum
• --nray — number of rays per detector (default = 1)
• --rotangle — degrees to rotate view through (multiple of PI) (default = 1)
• --geometry — geometry of scanning, choose your vibe:
  • parallel — parallel scan beams (default) 🌈
  • equilinear — equilinear divergent scan beams
  • equiangular — equiangular divergent scan beams
• --focal-length — focal length ratio (ratio to radius of phantom) (default = 1)
• --field-of-view — field of view (ratio to diameter of phantom square) (default = 1)
• --trace — trace level to use, one of:
  • none — no tracing (default)
  • console — trace text level
• --verbose — verbose mode 🗣️
• --debug — debug mode 🐛
• --version — print version
• --help — print a terse help message

🎀 HISTORY 🎀

CTSim was begun in 1983 using MS-DOS and an EGA display adapter. the way that this predates most of us is wild 😭. In 1999 it was ported to GNU/Linux and later ported to Microsoft Windows. a whole glow-up arc, we love to see it ✨
