being in a new place means being exposed to bacteria, germs and virii that you've never been exposed to and your immune system hasn't defended against. after a while, once your body has built up its immunity to the local germs, you'll probably find you're not getting sick as often.

My HP-28S has been serving me well for the past 23 years and has been my favourite calculator to use. Recently acquired a second one off ebay so that I'd have one for work and for home

your copy of MCNP should have come with Vised, which is a visual editor that's supposed to help you create the geometry for your input file. there's a bit of a learning curve, but you might find it helpful in addition to using MCNP's built-in plotting. Personally I find it difficult to use so I...

localized hyperthermia therapy is a common technique for treating solid tumours

These are two that I've used Essential Physics of Medical Imaging by Bushberg et al (ISBN 0683301187) Physics of Radiology by Wolbarst (ISBN 1930524226)

salaries for medical physics residents vary, but will generally be around the $30-35k/year range

part of it I will use to pay off some of the previous economic stimulating I've been doing. The remainder will be used to do some more stimulating in the form of some much needed items and tools to refurbish my mountain bike.

Actually, there are plenty of job openings in medical physics. what's lacking are applicants with sufficient clinical experience to fill them. Part of the problem is that many graduate programs offer little or not enough exposure to the clinical side of things. Sure, you do research, but...

you will want to get into a CAMPEP accredited graduate program. Starting in 2012, the requirements for taking the ABR board certification exam will require completion of a CAMPEP accredited training program. You also have at least two (that I know of) very good medical physics groups...

There are two things this test checks for: x-ray and light field congruence (how far off is the center of the radiation field to the center of the light field) and x-ray/light field size (are they the same size). The light field is supposed to represent the area that is supposed to be...

have you talked to the counselors, or do they just don't know? Check the websites of med schools you want to go to. Give their admissions people a call and ask them. Find out what their course prerequisites are. Get ready to take the MCAT exam. It would not be unusual to have to take the...

yes. in practice, the x-ray tube is energized for the entire rotation. otherwise you're just wasting useful opportunities to collect additional data. Partial angle reconstruction is handled in the reconstruction algorithm and simply determines the number of projections used to reconstruct the...

this is still true. As I'm sure you're aware, scan angle normally isn't a parameter that's available to be modified. On all the scanners I've played with, when time is a modifiable parameter it usually affects the tube rotation speed. However newer scanners can use a partial scan technique...

if you're maintaining the same mAs per slice though, the mA needs to go up by 3/2 to compensate for the reduced scan time

There's nothing in the definition of CTDI that references the scan angle. Scan angle just determines the number of projections used to reconstruct the slice. Keep in mind that diagnostic dose estimates are just that, estimates. At best whatever number you end up with is only going to be...
