    Don't quote me on this because I only covered the topic briefly in some applied classes before doing 6 years of research, but if I remember correctly, you grab it with long tweezer…

    It's much more primitive than you think. Dose distributions are simulated based on a CT/MRI that was acquired before treatment (treatment often lasts weeks). Only minor corrections…

    Just defended my PhD thesis in medical physics. Worked on radiation therapy treatment planning, which combines optimisation theory with the physics of Monte Carlo particle transpor…

    I want to echo point #2 about listening rather than talking. When I first pitched my work to radiation therapy vendors at big conferences, I was expecting a kind of adversarial exc…

    I wish MUDs were featured more prominently in online gaming history. They basically defined my childhood, and I learned how to code by writing vendor bots on a MUD. Dealing with ed…

    In general, the field is split into imaging research (MRI, CT, Ultrasound, optical imaging) and radiotherapy research. It's a very applied field, the fundamental physics has been f…

    People who go straight from undergrad to PhD often take 5+ years (in the states and Canada, at least), especially in the experimental fields

    There's a cool dystopian-ey youtube video briefly looking into that topic, among other things: https://www.youtube.com/watch?v=YJg02ivYzSs

    I've had a similar experience. I'm in a hybrid field (medical physics) where half of the people are from pure physics and the other half from a more biomedical engineering backgrou…

    If you're writing papers in LaTeX, then https://www.overleaf.com should be good for you. Almost all of our department has started using it.

    This is actually what we do in radiotherapy nowadays, it's even called "inverse treatment planning". Basically a radio-oncologist or a dosimetrist contours (manually, with a pen) o…

    I've been using http://naturesoundsfor.me/ as they let you mix a bunch of sounds and control the relative volumes of each. I've settled on 40% "Creek" and 70% "Rain" for sleeping.

    McGill University doesn't use an .edu domain, I tried signing up in case they included it anyway but got nothing.
