Well, seems like everyone is going there for studies! This is good. I have a friend who attends Yale (a top US school) and was really pleased after going through the preparation that included a lot of practice material which you can find on applicationbootcamp’s guide. (NOTE this linked website is not a free service) I think that you can collect all the required information from this guide which may be of a good help for you..

Dear Dr.,

I am a diagnostic radiology resident and I am interested in knowing how to operate and deal with the CT workstation and I was hoping that you recommend me a source to read for this.

Thanks

Hey Papa, thanks for the reply!

I'm not 100% with you though.

You said YES to:

1: Is the reason soft tissue shows up on radiographs as differing shades of grey only because it simly absorbs less radiation than bone? or...

2: because radiation is able to penetrate soft tissue easier than bone, so when radiation hits soft tissue within the patient, some of it is absorbed, but some of it also also penetrates all the way through that soft tissue, hitting the plate turning it black - so in effect giving soft tissue a light/dark greyish image?

but NO to:

If 2 is right, is it correct in assuming that soft tissue not only aborbs radiation (albeit it less than bone), but radiation normally penetrates right through soft tissue aswell hiting the plate and turning it black. So in effect soft tissue is a mix of grey absorbtion (mAs) and black penetration (kV) all rolled into one?


Maybe it was the way I worded it:

Using your bush analogy:

A:Light/Radiation that penetrates a bush (human body) that passes through the gaps in the bush/human body untouched (no interaction) will reach the plate and turn it black once processed.

B:Branches and twigs/bones and soft tissue) that absorb the light/radiation will show up as white/grey respectively.

C:Am in correct in saying that bones normally permit no penetration because it's been absorbed/soaked up by the bone, hence casting a white shadow onto the plate.

D:Softer tissue (whilst aborbing a lesser amount of radiation due to it's lower atomic number) absorbs all that it can, and then casts a greyer shadow onto the plate.

E:Is it correct in saying that bone and soft tissue normally permit no penetration (no rays passing through them to hit the plate), only varying degrees of absorbtion whose shadows are then cast onto the plate and recorded?

F:The only rays that actually penetrate the boy are those that pass all the way through untouched reaching the plate which in turn turns it black, hence once the radiograpjh is processed, we have black penetration, and differing shades of grey and white abrosbtion? Absorbtion meaning that bo rays have passed right through the bone or soft tissue, jus rays that have been soaked up to to varying levels (contrast)?

Re my clavicle and rib questions, it's not homework, it's just me trying to put all this into perspective, and understand it for myself, as I worry that if I can't understand this, then I'm gonna make a useless radiograopher lol

Ok,

The outer ribs are whiter than the inner ribs on a radiograph because the rays have been had to be absorbed by both posterior and anterior ribs, so cast a greyer shadow onto the plate?

Re the claivicle qustion,,.,u gotta help me ou there...

I was not able to locate a resource for general information regarding US college admissions for foreign nationals.

My suggestion would be to identify the colleges to which you would like to apply. Visit their website for specific information on admissions requirements for foreign students.

Each college website that I visited seemed to have similar requirements, including transcripts in English, and documentation through your Embassy.

Good luck!
