Cardiology Exam Preparation
Introduction
Measurements and calculations derived from ultrasound images 
are intended to supplement other clinical procedures available 
to the attending physician. The accuracy of measurements is not 
only determined by the system accuracy, but also by use of 
proper medical protocols by the user. When appropriate, be sure 
to note any protocols associated with a particular measurement 
or calculation....

Cardiology Measurements
Overview
Cardiology measurements offer two different types of 
measurement studies, Generic and Cardiac. 
•  Generic – Each exam category has a Generic study. The 
Generic studies provide you quick access to measurements 
such as volume, angle, A/B ratio, and % stenosis. For 
details on most of the generic measurements, See ‘Generic 
Measurements’ for more information. This chapter includes 
a...

Cardiac Measurements
This section lists cardiac measurements and the steps to 
perform them. The measurement information in this section is 
organized by mode, then by region of interest, and then by type 
of measurement. The organization is as follows:
•  Mode; there is a section for B-Mode, M-Mode, Color Flow 
Mode, and Doppler Mode. There is also a Combination 
Mode section, which includes calculations that are a result 
of...
