infection completely, image guided surgery should also be done to
follow up
B) image guided surgery is best done without taking the time and
expense of doing CT scans prior to surgical procedure
C) approaching the infected sinus directly by severing the cheek
muscles and puncturing the cheek bone are the current preferred
surgical techniques
D) image guided surgery can hero ensure better outcomes, as the
otolaryngologist can have clear visual confirmation of what tissue is
being removed
D
image guided surgery for hip replacements/repairs
A) 3 fiduciary calibration points are fixed to the patients body
B) the incisions needed are much smaller than standard surgical procedures
C) the instruments used for the operation have 3 calibration points
D) Recovery time is generally quicker than standard surgical techniques
E) all of the above

the invention disclosure form is used by the USF technology transfer
office to:
A) make the final patent award
B) make a direct submission of the form to the US patent office
C) evaluate whether USF should patent a new invention by a faculty
member or student
D) determine for the inventors what % of the royalties they will receive
C
in a carotid endarterectomy
A) use of markov models and quantitative patient counseling can
help doctors and patients make good decisions about carotid surgery
options an outcomes
B) the jugular wein in the neck is cleaned out surgically using a
temporary bypass
C) x-rays repeated many times during the operation reveal the way
to surgically isolate the carotid artery
D) surgery is ill-advised, as the patient will likely die of
extreme blood loss
A
markov models:
A) cannot be useful for real decision making they are unfeeling
theoretical concepts only
B) are used only in biomedical engineering, with no
generalizability to other fields
C) are useful when a decision or problem involves risk that is
continuous over time
D) can be evaluated using matrix algebra, but not as a cohort
simulation, nor as a monte Carlo simulation

B) Utilization of affymetrix gene chips that measure gene
expression for over 22000 genes
C) Regression, or correlational analysis of the genotype and phenotype
D) immunocytochemisrtry of cochlear protein expressions
