X Ray Contrast Agents
A) Explain what an X-Ray contrast agent is.
B) Give two important characteristics of an X-Ray contrast agent
C) Give two examples of X-Ray contrast agents used in medical imaging including what clinical applications they are utilized for
A
Contrast agents are substances used to enhance the visibly of internal body structure while doing x-ray based radiographic procedures like CT scan, fluoroscopy .
The contract agent may be injected or orally administered. They
do not permanently colour the body internal parts but only create
temporary contrast colour.
B
important characteristics of x-ray contrast agents:
a) Should be able to colour the body parts thus creating contrast
b) should not cause any temporary/permanent damage to the body parts .
C
Barium meal is used to create contrast in Gastro Intestinal track by making it opaque.
Iodine based compound are injected intravenously to create contrast for CT scans ,

Can someone please explain to me, why the current affects the x ray image contrast and the density of the x ray image? Also then again why would does the voltage affect these contrast and density. Would they affect the x ray image in any other ways And also what specific factors would you use these for in medical imaging using x rays - e.g. mammography, imaging of the lungs, please don't just state what, but explain why as well?
Problem 2. X-rays a) Maybe the most common characterization method that uses X-rays, is X-ray Absorption Imaging. This is basically the same technique as used in hospitals and dentistry. i. What is the sample/ material parameter that makes contrast (dark/ bright image features) in an X-ray absorption image? ii. Explain what is meant by (2D) X-ray Absorption Imaging being a “shadow image”. iii. What limits the resolution in an X-ray Absorption Image? b) Most X-ray based spectroscopy techniques have an...
a) Draw a diagram of an x-ray image intensifier used for medical fluoroscopic imaging. Label the 6. main components and explain their functions (10] b) Explain what is meant by the brightness gain of an image intensifier. Name and describe the two processes that contribute to this gain. Give expressions or numerical estimates where appropriate 15) c) Suppose that an x-ray beam is incident on an image intensifier having a diameter of 30 cm. For this x-ray beam, the incident...
33. Provide at least two examples where excellent projection and positioning in X-ray imaging can be used effectively to reduce patient exposure and provide radiation protection

Biomedical Imaging (x-rays); Please show all work! Specialized X-ray imaging methods 2.16 In mammographic examinations, the breast is compressed between two plates. Answer the following with a brief explanation (a) Is the geometric unsharpness increased or decreased by compression? (b) hy is the image contrast improved by this procedure? (c) Is the required x-ray dose for a given image SNR higher or lower with compression?
In one to two paragraphs. Explain Agency Theory. Give two real examples of where the agent works against the interest of the company. How could governance help protect the company? Why did it not work well.
The lifespan of an X-ray tube used as part of an X-ray imaging machine follows a normal distribution with a mean of 7 years and a standard deviation of 1.65 years. Standard Normal Distribution Table a. Calculate the probability that a randomly-selected X-ray tube will have a lifespan of: (i) Less than 4 years P(X< 4) = 0 (ii) Greater than 9 years P(X > 9) = 0 (iii) Between 5 and 8 years P(5< X < 8) = 0...
Two agents have identical quasilinear preferences U(x, y)-u(x) + y, where , x , x E [0,1] Agent 1's endowment is (3/2, 1/2) and agent 2's endowment is (1/2, 3/2). Normalize so that the price of good 2 is A) Calculate a Walrasian equilibrium at which the price of good 1 is greater than 1/2. Are there other Walrasian equilibria? B) Suppose agent 1's endowment were (2, 1/2). Find a Walrasian equilibrium for this economy. Note that agent is actually...
Pure Exchange Model 1. Consider a Pure Exchange Economy with two agents A and B and two goods X and Y in which each agent acts competitively. Their preferences are given by the following utility function U(X,Y)=X13*Y23 Their initial endowments are as follows W=(5,20) w- (25,10) a) Calculate the demand functions for Good X and Good Y for each agent. b) State the equilibrium conditions for this economy. c) Using these conditions and the demand functions found in part a)...
