Chapter 21 Digital imaging Exposure Techniques Exam Questions and Answers 100% Pass When developing exposure factors for a digital imaging system, which of the following factors no longer needs to be considered? a) body habitus of the patient b) ALARA c) optimal kVp settings d) all of these must still be considered - d) all of these must still be considered If a technologist fails to properly center over the appropriate automatic exposure control(AEC) cell, what undesirable results are likely to occur? a) underexposed and mottle b) overexposed and saturation c) underexposed and histogram errors 2100% Pass Guarantee Katelyn Whitman, All Rights Reserved © 2025 d) scatter fog and increased exposure index values - a) underexposed and mottle If a technologist fails to properly align to exposure field with a digital image receptor, what undesirable results are likely to occur? a) underexposed and mottle b) overexposed and saturation c) histogram errors & suboptimal EI values d) scatter fog and "ghosting" - c) histogram errors & suboptimal EI values The software function responsible for evaluating the collimated borders of an exposed imaging plate is called: a) algorithmic application b) exposure field recognition c) image equalization d) postprocessing - b) exposure field recognition One of the problems identified with the technologist interface with digital imaging systems and technique selection is that: a) visual cues indicating over-or-underexposure are no loner present on the image b) the image can be easily sent to remote locations 3100% Pass Guarantee Katelyn Whitman, All Rights Reserved © 2025 c) kvP manipulation is severely limited compared to film/screen systems d) automatic exposure control systems cannot be used in tandem with digital systems - a) visual cues indicating over-or-underexposure are no loner present on the image T/F The 15% rule can be used to adjust technique for changed patient thickness. - true T/F Digital imaging systems are inherently mAs driven. - false T/F The field size must be large enough so that at least 30% of the image receptor is exposed. - true T/F It is recommended that all exposures be made using a minimum of 70 kVp. - false T/F To avoid image mottle, expose all digital ima
