Medical Physics Option? WTF!?! (1 Viewer)

[Sprach]

Where the hell was the rest of it? There was no mention of endoscopes (lol one of the major things i studied), not too much about radio isotopes or anything, they seemed only to concentrate on MRI/PET and that crap... i was pretty pissed with that!
oh well it is over now only 3 more to go

 

[tegs]

I was pretty pissed that it didn't have much on MRI. One mark!!! I studied heaps for that!!!

 

[ND]

At first i was kinda thrown off by that 8 marker, but hopefully i'll get 6 or 7.

 

[Squirrel]

what properties of ultrasound make it suitable for finding bone density ?????????

 

[Sprach]

rofl i said that the ultrasound could pass through the bone and then measured on the otherside to see how much was absorbed

 

[smeyo]

yeah i studied heaps on mri and there wasnt much on it, but there was heaps on PET, luckily i knew that alright....heaps on x-rays, but whatelse are they going to ask... really it was alright

 

[Sprach]

un what about endoscopes? THINK OF THE ENDOSCOPES!
also for the 8 marker i just wrote about how they used the props of electrons with the actual scanning and also with their monitoring devices such as CRO's and CRT monitors? was i right with the CRO and CRT's? please say yes

 

[smeyo]

for ultrasound in the heel it is the attenuation and absorption of it through the heel, compared to normally when it is reflecftion

I rocked the medical

I loved the 8 mark question.

 

[~TeLEpAtHeTiC~]

medical was sooo cool... everything in there i knew..only think that threw me off was the bone scan VS xray..cause i only looked over that..but its all good.. loved the 8 marker aswell..

err.. not exactly.. we are talking about electrons and the development of CAT and PET heres an outline of the four page essay i wrote on it:

- nice fluffly intro
- explain how CAT works, using X-Rays
- explain the need for the understanding of electrons, explaning how X-Rays are produced; which all ties in nicely with electrons in the tube being accelerated etc. causing electrons to jump orbits releasing energy didfference in X-Rays
- talk about PET works
- do the same thing; mention electrons.... and especially interactions of the electrons and positrons
- short conclusion

btw i briefly mentioned electrons in the gamma camera

w00tah i hope it gets me good marks

and about ultrasound.. yes its attentuation and absorption for bone density.. i wrote a whole page on it anywayz

 

[Sprach]

yeah but it said the production and display of the images that are created, thats why i mentioned the television (CRT) and the heart monitor (CRO), if it didn't say DISPLAY in the question i would not have mentioned them, but thats why i put em in any comments?

 

[Bepps]

bloody-bloody. I forgot how X-rays were made!! I started talking about damn safety issues and with 20 minutes to go (and still having not done multiple choice) i remembered that X-rays were made with electrons. Might get 6 if i'm lucky, i did 2 booklets on the option. The rest of the test was pretty good though. I hope chem is the same!!

 

[Bepps]

OH CRAP!!!DISPLAY!! Make that estimate 3/8...

 

[Sprach]

yeah that display bit is what made me stop and tink about CRT/CRO, it was just stuck there hiding on the end lol... glad that i mentioned it

 

[smeyo]

shit i missed the display part i just talked about how understanding electrons also greater knowledge about how they work allows a clearer image to be obtained, talked about from xray 30 shades of grey to 256 in CAT and even better in PET, hope thats good enough for display, i saw it at the end and thought well that can do, cant be bothered doing more for it

 

[sukiyaki]

that was soooo bad.. that whole section...

there practically not much ultrasound... n argg the stoopid pet and x rays questions.... wish they had more ultrasound questions!!

 

[Sprach]

not much ultrasound?!?! 6 morks worth!!! i am more pissed about the no endoscope crap!

 

[sukiyaki]

the 6 marks were not verry broad thoz..
yeh more endscopes !

 

[Ragerunner]

For CAT I talked about how X-rays were produced by changing the kinetic energy to electromagnetic radiation when it hit the anodes and decelerates.

For PET I talked how an electron is a 'matter', a positron is an 'anti matter', they both collides produce gamma rays with the equation

e + e = 2 gamma

etcc.... blabbered on for 3 pages.
