Thermodes

	CHEPS standard thermode (27mm diameter)
	fMRI thermode for CHEPS (non-magnetic 27mm diameter)

Digital Calibration Kit
Used for checking and calibrating the temperature calibration of the CHEPS, this can be a requirement of certain grant-funded research/study protocols.

CoVAS
CoVAS is a hardware accessory package for use with the CHEPS system. CoVAS offers computerized, real-time, continuous VAS evaluation – adding an important dimension to pain threshold measurements. It can be used for continuous monitoring of response during therapeutic and experimental sessions, as well as measuring outcomes in pharmacological drug trials.

A patient-controlled potentiometer, or slider, is utilized and the thermal stimulation and patient response curves are synchronized and available for export to a variety of spreadsheet programs for analysis.

CoVAS is also available in a special non-magnetic version for use in an fMRI environment. The hardware is modified to work inside the MRI exam room, connected via a long cable to the CHEPS cart, located outside of the MRI room.

fMRI Filter

Used to prevent mutual magnetic interference / noises between the MRI device and the thermode.

PATHWAY Parallel Control
PATHWAY Parallel Control is an add-on PATHWAY feature, allowing researchers to manage test methods & protocols using external 8-bit interface commands. This feature helps the researcher in determining which test from the PATHWAY data base would be best to use.
Parallel Control interface is available for PATHWAY v3.2 and up and requires additional installation to the standard PATHWAY program.

The Parallel Control interface allows running a test automatically from a list of 255 predetermined programs which are saved in the PATHWAY program data base.
