I. How to use the volume view feature
How to select which calculation to display

You can view the diffusion phantom using the 3D Volume View feature. You can select which calculation you would like to view in the “Volume” drop-down menu. 

How to change the phantom anatomical view

You can select which anatomical view you would like to view your phantom. You can also click the magnifying glass to view specific anatomical views in the large viewing section. 

How to visualize geometric distortion effects

You can use the “Window” feature with each calculation to adjust the DICOM window to observe geometric distortion in the acquisition image.

How to visualize B0 and coil homogenity effects

You can use the “VOI Opacity” feature with each calculation to adjust VOI opacity to analyze B0 and coil homogeneity.

Study Information

Section I. View your Study information and protocol conformance

At the top of your Protocol page are two columns:

1. Study Information

2. Protocol Conformance.

The Protocol Conformance section shows why qCal marked your upload as partially compliant to the expected and recommended protocols if the conformance is marked as “partial.”

If the conformance is marked as “passed,” a green checkmark will indicate that the protocol inputs were sufficient and no values exceeded the limits.

Section II. View complete Study calculations

On each protocol page qCal shows all the calculations included, You may click on each calculation to go to its detailed calculation page.  

Section IV. View ADC VOI statistics

qCal displays your phantom’s ADC measurements compared to temperature-corrected NIST traceable values and automatically calculates the mean bias, bias percent, max b-value dependence, SNR B0, repeatability coefficient (RC), random error, and within-subject coefficient of variation (wCV).
