Thank you, Ray and hello everyone. Fourth quarter revenue increased 13.1% to $5.7 million, compared to $5 million in the year ago quarter. We've redefined our business segments to better reflect our revenue sources. Rental revenue from the company's medical equipment leasing segment, which we'll refer to as leasing going forward, was $4.8 million for the fourth quarter 2023, compared to $4.3 million in the year ago fourth quarter, an increase of 12%. Revenue from the company's direct patient services or retail segment was $913,000 for the fourth quarter ended December 31, 2023, compared to $764,000 for the same period in the year ago quarter, an increase of 19.5%. Fourth quarter revenue for the company's proton therapy system in Florida was $3.1 million, an increase of 39.9%, primarily due to continued increases in average reimbursement as well as an increase in fractions. Total proton therapy fractions in the fourth quarter were 1275 compared to 981 proton therapy fractions in the fourth quarter of 2022, an increase of 30% or 294 fractions, which is within the typical quarterly fluctuation range. Total Gamma Knife revenue decreased 8.4% to $2.6 million The decrease in overall Gamma Knife revenue was primarily due to a decrease in procedures from two expired contracts as well as downtime at two sites for the installation of upgraded equipment. Total Gamma Knife procedures were 277 for the fourth quarter, compared to 329 in the fourth quarter a year ago, a decrease of 15.8%, or 52 procedures, reflecting the two expired contracts and downtime for upgrades that were mentioned earlier. Gross margin for the fourth quarter of 2023 increased 24.1% to $2.8 million, compared to gross margin of $2.3 million for the fourth quarter of 2022. The gross margin percentage reached a record high of 49.4% compared to 45.1% in the comparable quarter, the highest it's been since 2019. Selling and administrative costs increased by 23.9% to $1.8 million in the fourth quarter of 2023, compared to $1.4 million in the year ago quarter. This includes approximately $350,000 that we've invested in pursuing new business opportunities, as Ray talked about, as well as higher sales and marketing expenses. Net interest expense was $175,000 in the 2023 period, compared to $192,000 in the comparable period of last year. The decrease is due to an increase in the interest rate on the company's variable rate debt offset by increases in interest income on the company's growing cash balance. Operating income for the fourth quarter of 2023 was $407,000 compared to operating income of $590,000 in the fourth quarter of 2022, which reflects the higher selling and administrative expenses plus an increase in reserves for impaired assets and removal costs of 362,000 in the current period. Income tax expense was $338,000 for the fourth quarter of 2023, modestly higher compared to income tax expense of $333,000 for the same period last year. This was primarily due to the higher taxable income offset by permanent tax differences recorded last year. Net income attributable to American Shared Hospital Services in the fourth quarter of 2023 was $415,000, or $0.06 per diluted share, compared to net income of $246,000, or $0.04 per diluted share for the fourth quarter of 2022. Fully diluted weighted average common shares outstanding were 6,552,000 and 6,284,000 for the fourth quarter of 2023 and 2022, respectively. Adjusted EBITDA, a non GAAP financial measure, was $2.7 million for the fourth quarter of 2023, compared to $2.2 million for the fourth quarter of 2022. At December 31, 2023 cash equivalents and restricted cash was $13.8 million compared to $12.5 million at December 31, 2022. Shareholders equity excluding non-controlling interests in subsidiaries was $22.6 million or $3.59 per outstanding share at year end compared to $21.6 million or $3.50 per outstanding share at December 31, 2022. This concludes the formal part of our presentation. Thank you for joining us today and we look forward to updating you on our progress in the quarters ahead. Betsy, we'd like to turn the call back to you and open it up for questions.
