Thank you, Rashed. As usual, I would like to start with the key highlights on the quarter. First and most important, to drive clinical adoption of TULSA technology, it is about clinical data. Treatment options is one of the top 2 topics researched by prostate cancer patients before they undergo any procedure and clinical data is very important to them in making the right selection. The 4-year follow-up data from our TACT pivotal clinical trial of whole gland ablation were presented by Dr. Laurence Klotz, one of the study's investigators at the recent FOCAL 2022 conference in September. As you may recall, the primary efficacy and safety endpoints of TACT were PSA reduction at 1 year and the frequency and severity of adverse events respectively. At 1 year, PSA decreased 95% from a median pretreatment baseline value of 6.3 nanograms per milliliter to a nadir of 0.34. By 4 years, the median PSA nadir further declined to 0.28. Importantly, PSA reduction was durable over the extended follow-up period, increasing just 0.33 from 0.53 at 1 year to 0.86 nanograms per milliliters at 4 years. The 1-year TACT data showed that following treatment with TULSA-PRO, there were no grade 4 or higher adverse events, no rectal fistula or injury and no intraprocedural complications. At the 4-year follow-up there were no new device or treatment-related adverse events. TACT's secondary endpoints included progression to additional treatment for prostate cancer and functional side effects commonly associated with current prostate cancer therapies, including erectile and urinary functions. At 4 years, only 16% of patients in the TACT trial underwent additional intervention for prostate cancer. This percentage compares very well to additional intervention needed after the current standard therapies. In terms of functional side effects, over the 4-year follow-up period, not a single patient experienced severe erectile dysfunction and 87% of previously potent patients reported erection, firmness sufficient for penetration, demonstrating continued improvement from 75% at 1 year. Urinary function was durable over the 4-year follow-up period with 99% of patients preserving urinary continence. Lower urinary tract symptoms were stable, improving from median International Prostate Symptom Score of 7 at pretreatment baseline to 5 at 4 years. I would like to emphasize that this was the first trial conducted in the United States using the TULSA technology. So most of the physicians who are part of the study have never performed the TULSA procedure before. And that -- this was whole gland ablation study. Despite that, these are outstanding results. And although this was a single-arm trial, the results compare favorably to any other type of treatment, including medical prostatectomy or radiation. In addition, I loved the title of Dr. Klotz's presentation as he put it eloquently and all guided TULSA, not just another focal therapy. Focal therapy has its place, but its applicability is limited to 15% to 25% of the patient population at best, whereas Dr. Klotz discussed with examples that TULSA is applicable to a majority of the patient population as it can easily be used for whole gland therapy, where that makes sense, or focal therapy where it makes sense instead. Indeed, that unique flexibility isn't just theoretical. About 3,000 patients have been treated with TULSA so far. About 50% of those have been whole gland and the other half focal patients. This quarter also marked a milestone in the SPARC study, a single center, investigator-initiated, randomized, controlled study of focal ablation versus radical prostatectomy or intermediate risk prostate cancer conducted by [Dr. Edward Taco and team at Algo University] in Norway. One-year follow-up has been completed for the entire patient cohort of 213 men with biopsy-proven MRI-visible unilateral prostate cancer who were randomized to receive either focal ablation using TULSA or HIFU or robot-assisted laparoscopic prostatectomy or RALT for short. The first report from this study with the complete cohort of patients has been submitted to the European Association of Urologists or EAU Annual Meeting next year. This first report focuses on comparing postoperative complications, demonstrating a statistically significant reduction of serious complications in the focal ablation arm. Additional reports with patient reported quality of life such as erectile dysfunction and urinary incontinence are expected to be presented along with early efficacy outcomes at additional conferences planned in 2023. Finally, we're continuing to make good progress in our sponsored CAPTAIN trial, which is the first Level 1 study ever conducted comparing emerging technologies head-to-head with medical prostatectomy in men with prostate cancer. To date, 8 sites have been activated and currently recruiting patients. Turning to the next key highlights. I'm pleased to tell you that we have now installed 30 systems in the United States and remain on track to achieve 35 installed systems by January 2023. I'm also pleased to report that most of the additional systems that will come online by January as a result of an agreement we recently signed with HALO Diagnostics for the installation of 4 TULSA systems at 4 sites, 2 in California and the other 2 in Florida. As you may recall, Dr. Scionti was one of the earliest adopters of the HIFU technology. To our knowledge, he has conducted more HIFU cases than anyone else in the United States and for many years was the lead educator and proponent of the technology to the urology community. He was also the first to use TULSA in a commercial setting in the U.S. and has performed approximately 90 procedures so far. Dr. Scionti is now the Medical Director of HALO's prostate program and he recommended that TULSA becomes HALO's primary prostate cancer treatment modality going forward and HALO agreed. We expect these to be higher volume sites with 3 of the 4 operational by year-end and the fourth that requires a new MRI coming on stream in January 2023. We're also happy to share that despite a slow start, RadNet is currently installing the system at their second site in Phoenix, which should be operational by year-end. Similarly, Paragon Imaging, another company with whom we have signed a multisite agreement, came on stream in the third quarter. So with 30 sites currently installed, we expect to reach 34 by year-end and the last of our 2022 target of 35 sites coming online at the beginning of 2023. While we remain confident that TULSA will change the standard of prostate care, I will be the first to admit that adoption at this early stage has been progressing more slowly than what we had hoped. Reflecting on our market entry strategy, our first target for early adopters, Dr. Scionti's practice treatment volumes and his successful recommendation to HALO is a case in point of the success of that strategy. Our next target were teaching sites of which we currently have over 15. We recognize that these would not be high volume sites, but we saw the value in their ongoing research to be presented to the urology community, conducting education programs for residents and other practicing physicians and providing the necessary support to the societies and payers for reimbursement. Indeed, that has also panned out very well. We had an excellent showing at the American Urological Association's 2022 Annual Meeting. Now we're expecting 5 podium presentations later this month at the world's largest radiology conference, the Radiological Society of North America or RSNA's annual meeting, which will further increase awareness of TULSA. The final target group, which is now our focus is higher volume imaging centers like RadNet, HALO and Paragon as we have signed multisite agreements with all of them and we're excited about their potential in 2023. So while the pace of adoption has not been as fast as we would like for a variety of reasons, there's no doubt that the strategy overall is working and that usage will continue to pick up. Turning to our reimbursement strategy. We announced in September that we withdrew our CPT Category 1 application for TULSA from consideration at the September 2022 CPT editorial panel meeting as the application only contains 2021 usage data. The withdrawal was due to the complete usage dataset not being available early enough for consideration at that meeting. We plan to submit an updated application with support from the same society and which will include all 2022 utilization in 2023. In the meantime, 11 hospitals are currently using the existing C-Code C9734 and are getting paid for their TULSA procedures. Earlier this week, [BMS] released its final OPPS reimbursement rule for calendar year 2023. As expected, the rule will increase reimbursement to a hospital billing under C9734 by approximately 3.6% to $13,048. With that change taking effect on January 1, 2023, we're pleased with this hospital payment level. Finally, the increasing number of TULSA sites and a growing set of utilization data affords a higher level of predictability of our U.S. TULSA business such that we expect to be able to provide some level of guidance beginning in 2023. To summarize, we are very pleased with the 4-year TACT data, which are even more compelling and demonstrate the durability of the TULSA treatment. We continue to get positive feedback from urologists regarding TULSA's flexibility that they can use it routinely for ablative treatment of whole gland or focal therapy or even for patients who have a combination of BPH and early-stage cancer. We will achieve our 2022 goal of 35 active sites in January with the newest sites expected to be higher volume than the teaching sites. We will re-file our CPT Category 1 application for TULSA in 2023 and have a higher level of confidence in being successful. While adoption has been taking longer than we originally expected, we believe that our overall strategy is working and that a few of the new sites that are coming on stream now are expected to be higher-volume sites. We look forward to providing some level of street guidance in 2023. This ends our prepared remarks for today. With that, Rashed and I are happy to take any questions you might have. Operator?
