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

Which of the following affect the resolution of a specific objective lens? CHECK ALL CORRECT CHOICES. Magnification Numerical Aperture (NA) Warelengthrofgnt combg tough t Field of View

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. 0000 1mm 2mm 3mm 4mm 1mm

In light microscopy, when magnification is increased, the lens focuses closer to the sample.  This makes the user more likely to ram the sample into the lens.  Why is it common for the lens to focus closer to the sample at higher magnifications? What can be done to mitigate this risk?

Define each of the following terms:  A) What is resolution and how is resolution related to the wavelength of light used to  illuminate the sample?  B) What is the magnification of the specimen if you are using a 40x objective and a 10x  eyepiece?  C) How is the numerical aperture (NA) of a lens related to its ability to gather light from a  specimen?

The diffraction limit is an unbeatable barrier limiting the effective resolution of light microscopy due to the inherent wavelength of light.True or False

A CST Is working with a Nuro surgeon on a left frontal craniotomy to remove a meningioma. He has just made the scalp incision when a unit charge nurse quickly enters the OR saying, "CSP just called and there was a malfunction of the stream sterilizer last night. The sterilizer chart doesn't confirm that these Instruments went through a complete cycle even though the biological indicator have a negative reading". 1)what steps should be 0R team take at this point? 2)what is the concern if the biological indicator have a negative reading? 3)discuss the chain of errors that took place that allowed the instruments to be transported to the OR, opened, and used
