You don't need anyone else's notes, what will help you the most is making your own notes!

Thank you! Fluoroscopy isn't my specialty, but my colleague and friend Don has a website all on it which he's continuously working on: www.angiographyandintervention.com/

This is the fun stuff though 😅

Certainly, I have a lot I can talk about on that topic. I’ll work on putting together my fav productivity apps first 👌🏼

This one is called Nocturnal Waltz by Johannes Bornlöf, I generally get the music for these videos from epidemic sound

Are you sure about Rhenium? All I’ve read on it and the data I’ve worked with says that it’s Rhodium (Rh), but I could be mistaken, could you send me a link

Here is a link to a slide I found saying rhenium

Glad it was useful :)

I should!

You're welcome!

Thanks Vincent, glad it was helpful!

Interesting! Thanks for sharing

That’s what I keep saying!

Thanks for the suggestion! Anything to highlight in particular?

@@SahandHooshmand I'd love to know what you do day-to-day and any productivity tips you have

Indeed they did, thank you kindly. Which one of my classmates are you?? Send me a message

So the RBE is used to compare the biological effects of different types of ionising radiation. It's defined as the ratio of the dose for our reference radiation (e.g. x-rays) to the dose of radiation in question (e.g. alpha particles) that would cause the same biological effect. If the latter requires 'less dose' to get the same 'biological effect' than x-rays, then we say it has a higher RBE (i.e. relative biological effectiveness). Essentially diving the x-ray dose to the alpha particle dose (both at their 50% survival fraction), that is if the alpha particle requires less dose for the same effect as x-rays, you'd be dividing by a smaller number, i.e. results in a larger number overall which is the RBE. Hope that helps!

MRI physics is a bit beyond my expertise at the moment but I'll see what I can do

It’s the energy required to remove an electron from an atom/nucleus, overcoming the electrostatic force holding it in place.

Will do

Just released, here it is: ua-cam.com/video/t8bySPYI0zo/v-deo.html

Generally speaking once you graduate (and assuming you have clinical experience) you can expect to apply for a 'Level B' academic, and the salary for that position start from a range of $110k-$130k AUD depending on the university.

I don't use telegram but I'm on LinkedIn! www.linkedin.com/in/sahand-hooshmand-phd-a72b97118/

Glad you found it useful!

I’m not entirely sure what you mean by blue or green screen cassettes 🤔 I’m assuming this is not related to digital image receptors?

Hey Vicky, good to hear! There definitely were times of stress, but I was quite lucky in that my manager was quite flexible with my hours if I needed some time off or swap of days, for me to work on my PhD stuff. I have 2 pieces of advice for you when you start: 1. Give yourself artificial deadlines. It's very easy to tell yourself 'I have the weekend to finish off my work', there are no classes or lectures to show up to during a PhD, it's mostly self-directed, only with fortnightly supervisory meetings. So, I found that when I gave myself artificial deadlines that for example, 'I need to finish this task by 5pm', then I was much more likely to get it done, and not have it disrupt my social life at nights and/or on the weekend. This is essentially leveraging Parkinson's law. 2. Find a way to make the work fun. I highly recommend Ali Abdaal's new book called 'Feel-Good Productivity'. I found when I liked my day to day work on it, it was like an adventure each day.

@@SahandHooshmand Thank you Sahand, both are great advices to get my life well-organized and motivated, and I think the first one has already worked on me very well. Please keep making videos, they are very illuminating. Also, for me, it's a good time to get myself started thinking about how to start this journey.

I'm Persian :)

Great question! The electron, being negatively charged, is indeed attracted to the positively charged nucleus due to their opposite charges. In the case of bremsstrahlung (braking) radiation, the electron approaches the nucleus and is deflected due to the attractive electromagnetic force. However, it's not a straightforward acceleration toward the nucleus because the electron doesn’t directly collide with it. Instead, as the electron passes by the nucleus, its path curves due to the attraction, which changes the direction and speed of the electron (i.e. velocity). This deflection leads to a rapid deceleration or reduction in the electron's velocity along its original path/trajectory. In this rapid deceleration, the electron releases energy in the form of X-ray photons, which are known as 'bremsstrahlung radiation'. So, while the electron does 'accelerate' in the sense that it changes direction due to the attractive force, it also loses energy as radiation because of this sudden change in velocity. Hope that helps

@@SahandHooshmand Thank u!

Wow this is very kind, thank you! I’m glad you found it useful
