Veenendaal, The Netherlands ( May 16, 2001 ) - Nucletron announces the first clinical treatments in the USA using SPOT™  (Sonographic Planning of Oncology Treatment). On May 14th and 15th David C. Beyer, M.D. and Fred Puente, CMD performed implants under guidance and planning from Nucletron’s SPOT™  at Arizona Oncology Services, Scottsdale, Arizona. The first treatment used iodine seeds and the second used palladium seeds. The SPOT™  system, now commercially available, incorporates the necessary, real-time imaging needed for an intraoperative treatment planning system which can begin to overcome some limitations of current pre-planning techniques.


"The power of SPOT™  , compared to the limitations of our current planning system, is that SPOT™  dosimetry reflects the real position of the needles at the moment of implantation. The SPOT™  system is an excellent first step toward achieving a comprehensive, real-time intraoperative system. It will allow me to improve the implant immediately in the OR," explained David Beyer MD.


Real-time planning allows clinicians to use the planning system directly in the operating room as a tool to improve the implant dosimetry by adjusting the placement of needles prior to depositing permanent seeds. The SPOT™  system offers the ability to guide needle placement using 3D ultrasound and dose images, which can be updated for each needle placement without disturbing the position of the prostate gland. Dr. Beyer was enthusiastic about SPOT™  , particularly the ability to show the real position of the needles at the time of implantation.


Recently, in Europe, Prof. Jan Battermann's team at University Medical Center, Utrecht (The Netherlands) introduced SPOT™ for intra-operative planning of prostate implants. Permanent prostate implants with iodine-125 seeds have been performed at Utrecht since the late 1980's and the technique continues to develop.


"Replacing pre-planning by intra-operative planning contributes to overall timesaving. The total implantation procedure is improved, since planning and insertion of the needles are done simultaneously….To date, at the UMC, we have implanted over 50 patients with excellent results with guidance by the SPOT™ system," states Prof. Battermann.


In addition to rapid acquisition of 3D images, SPOT™  innovations include 3D display of the image set, real time update of planned needle positions relative to actual positions, intra-operative dose calculation and dose volume histogram analysis.
