It seems like such a lovely, lovely idea for so many reasons, but then, I design particle therapy systems for a living so any time I see "yo let's pump ALL DA DOSE" my toes curl. We have finger badges, although TBQH I almost never use mine. They were much more a thing back when we did LDR implants (used radioactive sources that stayed in the patient permanently, and were radioactive as you placed them), but now HDR (high dose rate) brachytherapy with temporary Iridium-192 implants has really replaced LDR for most indications. These days the only thing we're implanting are plastic catheters for the radioactive seed to travel in. But yeah, we never ever use fluoro. Prefer to leave that to the cards/interventional rads folks. Particle therapy: a whole new level of BWM.

Residency Evil posted:Brachy's pretty neat in the right application. Particle therapy is absolutely the right way to do rad onc, the caveat of my employment being disclosed up front. Cyclotrons are BWRadiation because of the way that they deliver dose to the patient. Energy equals depth. The things are glowing hot since every particle they put downstream comes out at maximum clinical energy and then gets retarded back to whatever energy you want to match the tumor depth in the patient. Every bit of retardation means that the beam is getting bigger, so your accuracy gets shittier, and you're actively irradiating the retarders, which then leads into range shifters and apertures and all the things from the bad old days before multileaf collimators and those things glowing hot. It's additional dose for no added benefit. One of the vendors attacked the beam size problem by throwing a multileaf collimator on the end, but then you have a permanent radiation source right next to the patient. To tie into BWM, this also means that the cost of ownership is like 25x what it could potentially be. The GWRad way to do it is either a synchrotron or a FFAG. To tie this into a classic BWM story: There was a company named Twin Creek that made high current 2 MeV hydrogen accelerators, the idea being to do kerfless solar wafers. Clever idea but they ended up getting bought by GTAT for something like $10M, with the technology to do kerfless saffire for iphones. The CEO and CTO ended up getting a bunch of stock from GTAT and stayed with GTAT for some time. They ended up selling most of their GTAT stock before the bankruptcy. After the GTAT bankruptcy, they bought their old company and all the equipment for $1.2M, and turned it into a source for boron neutron capture therapy. They'll probably end up selling to Varian in a few years. Way to go, GTAT. Edit: Ooh, I forgot, when Twin Creek got bought, Mississippi took a bath on a production facility. Go go GTAT.

Cockmaster posted:I thought that technology had proven to be a legitimate improvement over plain old gamma radiation - the idea being to shoot out positrons which get annihilated at a particular distance, as opposed to gamma rays which cook all tissue in front of the machine. From a pure technology standpoint, yes. With photon radiation, the beam's energy ends up getting deposited along the entire length of the beam's path through the patient. It travels completely through and there's an exit dose. These days, we use inverse planning to enable us to dynamically shape the beam in sophisticated ways while treating with moving arcs around the patient. Soon, we'll even be able to move the couch the patient's on while doing that. Really science-fiction stuff, but at the end of the day the beam will still end up traveling completely through the patient. The machine that does that costs somewhere around $3M and can treat about 20-30 patients per day. Protons/charged particles travel in to the patient, deposit their energy completely to a point, and then essentially stop, without giving an exit dose. Great in practice, and super useful in specific situations, such as when we're treating tumors around the spinal cord, base of the skull, and in pediatrics, where lowering the integral dose makes a real difference in preventing cancers from developing 40-50 years down the road. If we're completely honest, we'd treat all patients if protons if we could, because the radiation plans end up looking better on paper in almost any situation. In practice, the "cheapest" proton unit costs about $20-30M per gantry. Multi-room setups that use a giant cyclotron have 4-5 patient treatment rooms and cost somewhere around $150-200M. If we're honest with ourselves, there are perhaps a few thousand cases in the US per year that truly would benefit from proton therapy over photon therapy, and it would be most cost effective to just fly those patients to those centers/put them up for a few weeks. Those few thousand cases a year aren't enough to keep the lights on in a $200M dollar facility, and what ends up happening is that many of those centers end up treating diseases like prostate cancer that don't really benefit from the treatment in any real way. The fact that prostate cancer specifically used to reimburse insanely well for proton treatment means that these centers have popped up all over the country, and there have been cuts in the last few years that have put even more pressure on these centers, to the point that some have gone bankrupt. Tim Thomas posted:Particle therapy is absolutely the right way to do rad onc, the caveat of my employment being disclosed up front. Huh, interesting. Does the energy issue also apply to newer pencil beam systems as opposed to the passive scattering ones? I was under the impression that PBS systems varied the energy coming out of the cyclotron, as opposed to requiring material to reduce the beam energy near the patient/generating neutrons. Also, I've definitely posted more radiation talk in this thread than the Goon Doctor threads.

What can protons do that like an electron beam can't? Fire protons? Firing protons or neutrons at atoms is good for making short lived isotopes, you know for medical uses. People seem to go crazy about anything like this, especially making a big fuss about a cyclotron that was built for this medical purposes. Of course the people complaining have no idea WTF they were complaining about. Anyway back to mega BWM. quote:O'Brien, a telecoms billionaire who became Ireland's richest man, is still in control of the Irish publisher. http://www.stuff.co.nz/business/world/90959598/the-rise-and-fall-of-a-british-billionaire-lion-sir-anthony-oreilly Doesn't seem like much of a billionaire when he owes that much and can't service the debts.

He could potentially sue them in small claims court if Amazon has a presence in his state, although he may not get the full $12000 depending on limits in his jurisdiction. Sure he's scamming them, but it's not like Amazon told him he was a scammer. They just complained about his return rate and said he'd get a check in the mail. So he could sue them and he might win. And then Amazon goes after him for all the products he's scammed and turns his life into a living hell. Best to just slowly back out of the room and count himself lucky.

They've told him they don't wish to do business with him anymore, so he'd have to misrepresent himself to sneak back in. Besides, the dude was getting 30 parcels a day, and returning 7% of them. If a brand new customer in the same town starts doing that same pattern, their fraud department would likely catch on pretty quickly. Like when a goon gets a permaban and it should be easy enough to register a new account, but apparently it's ridiculously hard not to immediately go back to the patterns that got them banned in the first place.

It's so good that the company selling dirt for nearly 5 figgies can't figure out how to use apostrophes correctly  It's probably not a very good heuristic but I am extremely wary of buying anything (much less $9,000 worth of dirt  ) from people who can't get basic spelling and grammar right. Too much ripoff potential there.
