Exam 11: Radiographic Exposure Technique

The indication of how much magnification is seen on a radiograph is

If 12 mAs produce appropriate IR exposure at 36 inches SID, how much mAs is needed at 72 inches SID to maintain that amount of exposure to the IR?

Which type of body habitus is the thickest, requiring higher exposure factors?

Whenever magnification is increased

Given 40 mAs, doubling the mA produces the same result as

Which of the following exposure factors produces the same amount of remnant radiation as does 20 mAs at 70 kVp?

Tube angulation may result in elongation and reduced exposure to the IR.

Increased collimation results in 1) less volume of tissue irradiated 2) less exit radiation reaching the IR 3) less scatter reaching the IR

With digital imaging, if the mAs is too high

The relationship between kVp and the quantity of remnant radiation is known as the

What type of relationship does kVp have with exposure to the image receptor (IR)?

Increasing the kVp has what affect on wavelength and frequency?

What type of relationship does distance have with x-ray beam intensity?

Increasing collimation means decreasing the x-ray field size.

Reducing the amount of scatter radiation reaching the IR results in

A compensating filter

Focal spot size affects only

When the intensities of radiation exiting the patient are very similar, the resulting radiographic image has

Too little remnant radiation caused by low kVp results in a digital image in which

A magnification factor of 1 cannot be achieved with radiographic imaging.
