○ IQ Enhance is compatible with 0.625 mm and 1.25 mm slice thicknesses. Interval for
acquisitions with IQ Enhance must be equal to the slice thickness (0.625 mm or 1.25
mm) or an overlap of 50% (0.312 mm or 0.625 mm).
6.3.3 Set the Recon Type
Use this procedure to set the Recon Type , which designates the algorithm used for image
reconstructions.
1. From the
Scan Settings
window, click the
Primary Recon
collection.
2. Click
Recon Type
.
3. Select the appropriate algorithm for the primary or first reconstruction.
The algorithms from left to right increase spatial resolution and decrease low contrast
detectability.
○
Click
Soft
for tissues with similar densities, but not useful for non-enhanced scans.
○
Click
Stnd
for routine exams, e.g., chest, abdomens, and pelvis scans.
○ Click
Detail
for post myelograms, where hybrid tissue detail and bone edges are
important.
○
Click
Lung
for interstitial lung pathology.
○
Click
Bone
for high resolution exams and sharp bone detail.
○
Click
Bone Plus
for sub mm detailed head work. It can be used for any study that
normally used the bone algorithm, but is very useful in cases where the
Edge
algorithm
was used. This is because the
Bone Plus
algorithm has no reconstruction penalty and is
very close in standard deviation to Edge .
○
Click
Edge
for small bone work in the head, as well as high resolution scans.
○ Click
Chest
for mediastinum and lung detail studies. It provides soft tissue resolution and
contrast when viewing the images in a soft tissue/mediastinal W/L and high resolution of
the lung tissue when viewing the images in a lung W/L.
NOTE: Cardiac scan mode choices are:
Soft
,
Stnd
,
Detail
,
Lung
and
Bone
.
4. If Hi Res mode is enabled, select a higher resolution algorithm that has similar
characteristics to the non-Hi Res algorithms.
