Design Case Studies
Lead collimator cross section & detector are on the left on this diagram, iso-response profiles are to the right
"Given one or more focusing collimators (and related electronics), develop a brain scanning system that shows increased sensitivity compared to a rectilinear scan using a single detector, and which gives a cross sectional image of the brain more suited for surgical planning than rectilinear scans."
Schematic of early tomographic scanner, U.S. Patent Number 3,591,806, eight detectors arranged in a circle with a common intercept point.
Mutually orthogonal schematic arrangement – one quadrant of a 12-detector system with 4 sets of three mutually orthogonal detectors
A means of monitoring patients for potential respiratory depression needs to be found, such that the patient in a step-down unit may be better monitored than just with simple periodic visits by hospital personnel.
While charting the pathway of patients through a screening clinic (breast cancer screening) a means had to be found to display not only the process but also the patient perception of the process.
Given the mandate to do so, design an introductory freshman module (1 credit hour) to allow students potentially interested in your department to sample what they might experience in their remaining three years should they elect your department's major.
The purpose of the test is to provide rough insight into whether plastic materials subjected to stress are compatible with common cleaning substances. The materials being considered are Valox, Zytel, Cycoloy, and Thermocomp.
