Dr Ronald Silverman had been using pulse/echo ultrasound to image the eye (Figure 2 left) but as a result of the CTSC he met and collaborated with Dr YC Chen of the Gene Center whose expertise is in applications of focused scanning laser technology. Their studies resulted in vastly (10 fold) improved resolution of photoacoustic  imaging of the sclera and choroid layers  over pulse/echo ultrasound imaging (Figure 2 Left). As a result of this breakthrough it will be possible to image many anatomical eye abnormalities/tumors at earlier stages or in greater detail.  The team is conducting further studies (with Gene Center nanotechnologist, Dr. Hiroshi Matsui) to improve contrast using gold nanoparticles and to reduce laser scattering for improved detection of tumors of the eye and skin. Their communication was facilitated  using technology provided by an NCRR-constructed  Internet2 videocollaboration facility at the Hunter Gene Center. 

Figure ## right shows Dr. Ronald Silverman (left at the podium, standing next to Mr Carlos Lijeron, (manager of Internet2 videocollaboration  facility) demonstrating video calling to his collaboration Dr Y.C. Chen located elsewhere, but appearing on the screen. The results already published will be described in the Winter 2010 issue of NCRR Reporter.
