Claim 0:
1. A food grade intra-oral ultrasound coupling gel comprising:
water;
a thickening agent for thickening the water into a gel, the thickening agent comprising a carbomer, wherein the carbomer is at a concentration of between 0.1% and 5% of the gel by weight;
a neutralizer for adjusting a pH level of the gel;
a viscosity agent for reducing changes of gel viscosity due to gamma radiation exposure, the viscosity agent comprising cellulose nanocrystals (CNC) and glycerin, wherein the CNC is at a concentration of between 2% and 15% of the gel by weight and wherein the glycerin is at a concentration of between 5% and 10% of the gel by weight;
wherein the gel has been exposed to gamma radiation;
wherein the gel has a post-radiation viscosity between 50,000 and 100,000 cPs when measured using a viscometer at 37° C.; and
wherein the gel has an acoustic impedance similar to soft tissue and is safe for ingestion.
