Final Exam 2024 In this take-home exam, you will think through a problem in stages, but first some background based on a question somebody asked me on the way out of class that sounded interesting so | wrote the whole final around it. Doppler ultrasound is a non-invasive test that can be used to investigate movement and particularly evaluate blood flow in arteries and veins. It can also provide information regarding the i i b Shaded area is known as pef'fusmn of blood flow in an organ or within an area s 0 of interest. A more generally to look at rhythmic egon Where \\ movement of tissue wall motion in the heart. signals (F) can only be The external phenomenon is a property of deced FynF, ~F, waves, that you will recall from basic physics, is called the \"Doppler effect\" where a transmitted frequency (Ft) is affected by the velocity of whatever it reflecting off of, causing the received velocity (Fr) to be \"Doppler shifted\" by some amount (Fd) 1: To measure anything we need a sensor, which consists of a measurable physical phenomenon, an effect that causes that phenomenon to change into something measurable, and a readout that we can actually work with. Of the sensors discussed in class, how will we sense Doppler Ultrasound? a.(2.5) Physical phenomenon: b.(2.5) Effect (DO NOT SAY DOPPLER!): .(2.5) Readout: 2: If you were tasked with building a Doppler Ultrasound, what is the key component that we use to produce and measure ultrasound? Whatever it is, it needs to generate a frequency of 2- 5MHz. a.(2.5)What material is the functional part of this component made from? b.(5)Find a really nice one on the internet that produces an appropriate frequency and post a link to the product technical data
