Abstract

Provided is a method of ultrasound diagnosis, wherein the method includes: coating a surface of a specimen with a transmission medium; and performing the ultrasound diagnosis, wherein the transmission medium has a viscosity of at least 1,000 mPa·s at 25° C. and contains a hydrocarbon compound.

Claims

C. and comprises a hydrocarbon compound, which is 2-methyl-3-methyl-2[(3-methylbicyclo[2,2,1]hept-2-yl)methyl]bicyclo[2,2,1]-heptane;

3-methyl-2-[(3-methylbicyclo[2,2,1]hept-2-yl)methyl]-2-[2,3-dimethylbicyclo-[2,2,1]hept-2-yl]methyl]bicyclo[2,2,1]heptane;

or

a mixture of 2-methyl-3-methyl-2[(3-methylbicyclo[2,2,1]hept-2-yl)methyl]bicyclo[2,2,1]-heptane and 3-methyl-2-[(3-methylbicyclo[2,2,1]hept-2-yl)methyl]-2-[2,3-dimethylbicyclo-[2,2,1]hept-2-yl]methyl]bicyclo[2,2,1]heptane.

2. The method according to claim 1, wherein said performing the ultrasound diagnosis comprises:

transmitting an ultrasonic wave through the transmission medium to the specimen; and

analyzing the ultrasonic wave received through the transmission medium from the specimen.

3. The method according to claim 2, wherein the ultrasonic wave is at least one ultrasonic wave selected from the group consisting of a transverse wave, a shear horizontal wave, a shear vertical wave, and a longitudinal wave.

4. The method according to claim 1, wherein the hydrocarbon compound is 2-methyl-3-methyl-2[(3-methylbicyclo[2,2,1]hept-2-yl)methyl]bicyclo[2,2,1]-heptane.
