Accuracy of ventricular volume estimation.

Accuracy of ventricular volume estimation.

Sources of error in the estimation of ventricular volume from CAT scans are discussed and the accuracy of the measurement assessed. Two methods of calculating ventricular volume from an intraventricular injection of radioisotope are described and compared. Finally, the CAT scan and isotope methods are compared and contrasted. The error associated with a single measurement of volume by any of th...

Estimation of absolute ventricular volume.

CHEST I 85 I 5 I MAY, 1984 711 not withhold any information from the patient or her physicians, and culture reports, which came from another institution, were not received by us until late in her terminal illness. We feel qualified to comment on tuberculosis, but do not claim similar expertise for AIDS. One of our internal medicine residents contacted the CDC regarding this patient, and they cl...

Bathymetry and Volume Estimation of Reservoirs using OLI Imagary

Nowadays using field depth measurement to estimate capacity of water reservoirs is a costly and time consuming method. In this regard, different multiple techniques of remote sensing method has been adopted. In this study, a radiation and reflection based model was introduced to estimating the bathymetry and water capacity of reservoir by images of OLI sensor. For this, at May 17, 2015 water de...

LABORATORY INVESTIGATION VENTRICULAR PERFORMANCE Accuracy of volume measurement by conductance catheter in isolated, ejecting canine hearts

We evaluated the accuracy of the recently reported technique of estimating intraventricular volume by measurement of intracavitary electrical conductance in six isolated, ejecting, canine left ventricles. Left ventricular volumes were measured directly by a previously validated servosystem that employed an electroconductive balloon placed in the left ventricular cavity. The volume measured cont...
