Ch 1-4 DMSO 1210 Exam 1 with correct
answers 100% 2026
Infrasound - Correct Answers <2 Hz
Audible sound - Correct Answers 2-20,000 Hz
Ultrasound - Correct Answers >20,000 Hz
Diagnostic ultrasound - Correct Answers between 2 and 15 MHz (or higher)
Acoustic windows (sonographic window) - Correct Answers Optimal location on body for
placement of the transducer to demonstrate both normal anatomy and pathology
Radiologist - Correct Answers One who interprets or reads imaging exams (cardiologists,
vascular surgeons and OBs may be the ones interpreting their respective scans)
Different types of imaging - Correct Answers Radiography, fluoroscopy, myelography,
arthrography, GI imaging, computed tomography (CT), mammography, positron emission
tomography (PET), nuclear medicine technology, magnetic resonance imaging (MRI), magnetic
resonance angiogram (MRA)
IMAGE process - Correct Answers Investigate history
Make hypothesis
Analyze with sonography
Gather findings
Evaluate for connections
, Sono images - Correct Answers Obtained in two scan planes- Sagittal and transverse
Sono reports - Correct Answers Docs with basic info about sono exam; compare normal and
abnormal but do NOT use diagnostic terms (see basic sonographic descriptive language)
Anechoic - Correct Answers Fluid filled structure, black on image
Echogenic - Correct Answers Bright/gray structure, produces echoes
Sonographic reasoning - Correct Answers 1- clinical history
2-clinical hypothesis
3- investigative imagine
4- Sonographic findings (recall clinical history and hypothesis)
5- clinical correlation
Sound - Correct Answers Form of energy produced when vibrating source causes molecules in
medium to move back and forth
Acoustics - Correct Answers Scientific study of sound
A-mode - Correct Answers Amplitude mode; represents depth of returning echo in x-axis and
strength of reflector on y-axis
Plus if sound sent out to create one scan line of info interpreted to represent depth and
amplitude
B-mode - Correct Answers Brightness; displays returning ultrasound signal as dot on monitor
(grayscale)
