Q

Longitudinal views

A

Show a structure’s length and depth

22
Q

Axial views

A

Show a structure’s width and depth

23
Q

Focal zone

A

Area where the sound beam is narrow and imaging is at its best

24
Q

Angle of incidence

A

The angle at which the sound beam strikes the surface of a structure

25
Q

Orientation

A

Lie

26
Q

Assessment notes

A

Results of the physical examination, including a listing of patient’s symptoms

27
Q

Differential diagnoses

A

Multiple pathologic conditions that may be indicated by the ultrasound findings and reported as such by the interpreting physician

28
Q

Hepatitis b virus (HBV)

A

Bloodborne pathogen that requires universal precautions to reduce exposure risk. Healthcare workers can protect themselves with the hepatitis b vaccination, which requires 3 shots over 6 months and is offered at most healthcare facilities

29
Q

Human immunodeficiency virus (HIV)

A

Bloodborne pathogen that requires universal precautions to reduce exposure risk. Virus may lead to AIDS, a deficiency of the autoimmune system that in many cases is terminal

30
Q

Interpretive report

A

Sonologist’s (radiologist, physician) formal, legal, interpretive report of the ultrasound findings

31
Q

Occupational safety and health administration (OSHA)

A

An agency within the United States Dept. of Labor. OSHA standards are designed to protect healthcare workers from major bloodborne diseases

32
Q

Patient chart

A

Compilation of patient information, including medical history, results of physical exam, patient’s symptoms, and laboratory test results

33
Q

Society for diagnostic medical sonographers and american institute of ultrasound in medicine (SDMS/AIUM)

A

Professional ultrasound organizations for sonographers and sonologists

34
Q

Sonographer

A

Ultrasound professional responsible for performing and recording ultrasound studies for physician interpretation

35
Q

Sonologist

A

Physician responsible for providing the final, legal, interpretive report (may include differential diagnoses) of ultrasound findings

36
Q

Technical observation

A

Sonographer’s written summary of ultrasound findings using sonographic terminology. Never a diagnosis, as it is not considered justified (level of education, training, experience) or legal

37
Q

Ultrasound request form

A

Patient identification data, clinical symptoms, and examination requested and why

38
Q

Universal precautions

A

Treating all patients as if they may have HBV/HIV of other bloodborne disease, meaning that engineering, workplace, and housekeeping controls are in place to ensure safety

39
Q

Additional controls

A

Imaging controls such as body pattern, Doppler, power Doppler, pulsed wave, M Mode, and screen monitor controls

40
Q

Alphanumeric Keyboard

A

Keyboard on the ultrasound system that allows alphabetical and numerical characters to be entered for the patient’s examination

41
Q

Calc key

A

Appropriate calculations package based on imaging preset

42

A

Acronym for Hospital Information System

45
Q

Knobology

A

Ultrasound system controls including 1) primary imaging 2) calculation, and 3) additional controls

46
Q

PACS

A

Acronym for Picture Archiving and Communications System. PACS enables improved image resolution as images are stored in digital format and manipulated by software controls

47
Q

Primary imaging controls

A

Controls such as imaging preset, frequency, depth, and time-gain compensation (TCG) that directly affect image quality

Q

RIS

A

Acronym for Radiology Information System. Electronic, radiology-specific network that supports imaging, reporting, and relevant patient data. RIS is generally a subsystem of HIS

49
Q

Teleradiology

A

Radiologists consult for imaging diagnoses using PACS to view images transmitted from site of origin

50
Q

Ultrasound field service engineer

A

Performs installation of ultrasound system at imaging site

51
Q

Ultrasound system

A

Software-based control system for image settings and measurements
