I am using Clarius HD3 probes (L15 HD3 and C3 HD3) for ultrasound phantom research using quantitative ultrasound (QUS) analysis of raw RF data. This research has lasted longer than necessary because of issues I continue to have from the Clarius probes. The current imaging presets on our probes rely heavily on automatic optimization, which is helpful for routine B-mode imaging but creates problems and is bad news for QUS analysis because RF measurements need repeatable acquisition settings. It has messed up our imaging and data for so long that we are now making a request for a fixed RF/QUS presets.
Therefore, could you please help us configure or provide us two separate presets for each of our probes, the L15 HD3 and C3 HD3, or guide us on how to configure them?
QUS / Raw RF Research Preset
Fixed, repeatable settings for RF acquisition.
Automatic image optimization should be disabled wherever possible.
The goal is to acquire raw RF data suitable for attenuation, backscatter, spectral, and texture-based QUS analysis.
Regular B-mode Imaging Preset
Standard optimized B-mode preset for locating anatomy/phantoms and routine imaging.
Automatic optimization can remain enabled for this preset.
For the QUS RF preset, we would like the following parameters to be held constant and documented for both the L15 HD3 and C3 HD3 probes:
Transmit center frequency / operating frequency
Receive bandwidth
Imaging depth
Focal depth and number of focal zones
Transmit power / acoustic output / MI / TI
Overall gain
TGC curve or depth-gain compensation profile
Dynamic range
Compression / log-compression settings
Time averaging / persistence
Spatial compounding
Harmonic imaging
Speckle reduction / image smoothing / noise reduction
Edge enhancement or other post-processing filters
Auto-gain, auto-depth, auto-focus, and automatic optimization controls
Frame rate
PRF / pulse repetition frequency, if applicable
Line density / beam density
Scan width or field of view
Sector angle for the C3 HD3
Aperture, apodization, and beamforming mode, if configurable
RF sampling frequency
RF data format, bit depth, scaling, and units
Whether exported RF data are pre- or post-beamformed
Any metadata fields needed to verify that settings stayed constant between scans
Ideally, the QUS preset would allow us to scan phantoms and samples with identical acquisition conditions across repeated measurements so that changes in the RF data reflect the sample properties rather than automatic scanner adjustments.
