QLVAPlus is a program for the quick, convenient and
accurate quantitation of left-ventricular volumes and
wall motion from left ventriculogram taken in the 30
degree RAO projection. It uses the Stanford radial method for
captured from an actual display (1/2 size)
QLVAPlus automatically optimizes itself for computer
display resolution settings.
Images of any resolution can be analyzed.
There is an
Auto mode where brightness and
are automatically adjusted order to
optimize image appearance.
The following data can be specified by the operator:
Heart Rate during angiography for the calculation of
Height and Weight for the calculation of Body
Calibration object size.
Pushbutton controls are used to step through the
measurement process. Data can be acquired in any order, at
any time. Each of these steps may be repeated as often as
The View button allows unobstructed viewing of the
The Calibrate button allows the user the specify two
points on a calibration object such as a
grid or sphere.
The Trace E.D. button saves the end-diastolic image
and allows the user to trace or edit the end-diastolic
The Trace E.S. button saves the end-systolic image
and allows the user to trace or edit the end-systolic
contour. End-diastolic and end-systolic contours are traced over the live image by clicking
the mouse at several points around the border of the
left ventricle. A smooth cubic-spline curve is fitted
to the points as they are entered. Points can be
added, deleted or moved in any order at any time.
Images with the contour superimposed can be scrolled
backward and forward to determine the best possible
fit - this is especially important when tracing the
The Print Report button will cause a complete QLVA
report to be printed with all of the data shown above,
plus end-diastolic and end-systolic images and Patient, Study, Series
and Image information.
The E-mail button will cause a complete report,
including images, to be sent by e-mail.
All common volumetric parameters are calculated and
displayed. Volumes are calculated using the Dodge-Sandler
Regional and global wall motion parameters are
calculated and displayed.
A standardized wall motion plot allows convenient
inspection of detailed wall-motion information.
