Thank you Paul. Welcome and thank you for joining us in our first quarter 2018 earnings conference call. As Paul noted, total revenues for the first quarter of 2018 increased 45% year-over-year to $313,000, from $216,000 in the first quarter of 2017. During the quarter, product revenue increased by $111,000 or 56% versus the comparable period of 2017. Gross margin was 65% for the quarter ended March 31, 2018 consistent with our expectations and in line with the 64% reported in the comparable period in 2017. Research and development expenses for the three months ended March 31, 2018 was $372,000, an increase of $15,000 or 4%, as compared to the three months ended March 31, 2017. This increase was primarily due to increased personnel costs. Selling, general and administrative costs for the three month ended March 31, 2018 were $2,236,000, an increase of $1,091,000 or 95% as compared to the same period in 2017. The increase was primarily due to increases in personnel cost of 595,000 which includes 310,000 for additional sales, marketing and personnel hired and share based compensation expense of $285,000. Other administrative costs increases include professional fees, rent, insurance and office expense of $268,000. During the three months ended, March 31, 2018, we had an operating loss of $2,403,000, as compared to an operating loss of $[1,363,000][ph] during the three months ended March 31, 2017. During the three months ended March 31, 2018, the company generated interest income as compared to interest expense - generated interest income of $42,000, as compared to interest expense of 141,000 in the same period in 2017. We did not incur interest expense during the three months ended March 31, 2018 due to the pay-off of our outstanding debt in our convertible promissory notes being converted in to common stock upon the closing of our IPO on June 9, 2017. The company’s net loss for the quarter ended March 31, 2018 amounted to 2,345,000, compared to a net loss of 1,556,000 for the corresponding 2017 period. Adjusted EBITDA for the quarter ended March 31, 2018 was a loss of 2,502,000, compared to a loss of 1,341,000 for the corresponding 2017 period. Cash on hand at March 31, 2018 was 14,160,000 compared to 12,959,000 at December 31, 2017. The increase in cash primarily reflects 3,550,000 of cash proceeds received from the exercise of warrants during the quarter, offset by cash used in operating and finance activities of 2,333,000. Before I turn over the call to Paul for Q&A, let me just mention some housekeeping items. Our first annual meeting will be held on June 19, 2018 in Boston and we plan on hosting our second quarter 2018 earnings conference call in August. Paul?
