IB Studying

I do have an end-of-IB post planned but it's not for today. Today I have Biomedical physics! Roi got a bunch of IB review packets and decided quickly to give up on biomedical physics, so I helped her study by filling out the packet. It's like 60 pages and most of my answers are random nonsense that I swear are hilarious after an hour of Spanish class (it's like pot, really), but here are some highlights:

Suggest why it is preferable to use this isotope for imaging the thyroid rather than iodine-131: Because it show's off the thyroid's curves better

State a possible cause of the hearing loss:

Frederick: Susanna yelled at him

Susanna: Frederick punched her

State and and explain one situation in which these diagnostic techniques would be used:

X-rays: Superman killing bad guys

Ultrasound: Sonic the hedgehog killing bad guys

Nuclear magnetic resonance: George Bush killing bad guys

Outline two precautions an X-ray machine operator should take to minimize his/her exposure to X-rays: Don't have sex with/in the X-ray machine

State one way in which a B-scan differs from an A-scan: It can't call for help from the A-team

(Explain, with reference to the diagram, why the force P and the compression force S on the spine are much greater than the weight of W on the upper body of the person)

Ah, Spanish class. So excruciating it makes Chuck Norris jokes hilarious.
