Solved in 2 steps
- Procedure 1 Magnification Light is refracted through two lenses to obtain magnification-the ocular lens and the objective lens. Magnifi- cation of the ocular lens is usually 10x.This means that if you were to view a slide with only the ocular lens, the image would be magnified 10 times. Magnification of the objective lenses varies, but typically is 4× for low power, 10× for medium power, and 40× for high power. (To verify that this is the case for your microscope, look at the side of the objective lens, which usually is labeled with its magnification.) Remember that oil immersion provides even greater magnification at 100×. When calculating the total magnification, you must multiply the magnification of the ocular lens (10) by the power of the objective lens. Fill in Table 3.1 to determine total magnification at each of the different objective lenses on your microscope. Remember that the magnification of the objective lens is usually printed on the side of the lens itself. ABLE 3.1…Show all work including equations. Patient is treated AP/PA parallel-opposed fields. The fields are set up isocentrically on a 6 MV Linac, The patient's AP/PA separation is 25cm, and the field size at midplane is 14 x 26 cm (W x L). Calculate the AP field size on the skin.Discuss SSD (non-isocentric) technique and SAD (isocentric) technique including the advantages and disadvantages of each type of setup.
- Previous question: The field of view is the maximum area visible through the lenses of a microscope, and it is represented by a diameter. To determine the diameter of your field of view, you can place a transparent metric ruler under the low power (10X) objective of a microscope. You would focus the microscope on the scale of the ruler and measure the diameter of the field of vision in millimeters. Refer to the image taken of this preparation below. What is the approximate field of view as seen by this 10X objective. Note: This microscope has a 10X eyepiece, giving a total magnification of 100X. The image shows the 1mm is for this question. - Answer for this question was 3mm.Describe three ways to increase the depth of penetration of electrical impulses when using pad electrodes.Problem: A prescription calls for 1% solution pilocarpine (freezing point= -0.14 degrees celsius) to be be made isotonic with tears using sodium chloride.

How many grams of sodium chloride must be added to the Pilocarpine solution to make it isotonic?
- The basic component of a fluoroscopic x-ray system suitable for interventional procedures consist of a generator,x-ray tube and housing including collimator and filtration,patient table,anti-scatter grid and an image receptor.Describe the key design features and function of each of these component and briefly discuss the role of automatic brightness controlPractice problems: Do on folder paper. 1. You are observing a cell; total magnification 100X. It looks like about 7 cells will fit across the field of view's diameter. How large is this cell? Explain. 2. For the 2nd specimen, you are using a total magnification of 400X. It's harder to estimate this time, so you approximated that 12 cells would fit across the radius. Explain how you would find out the size of one cell.The basic components of a fluoroscopic x-ray system suitable for interventional procedures consists of a generator,x-ray tube and housing including collimator and filtration,patient table,anti-scatter grid and an image receptor.Describe the key design features and function each of these components and briefly discuss the role of automatic brightness control
