At the beginning of the year, the all-new SOMATOM® Perspective CT scanner was installed in an imaging center in France. The first results are an example of how improved diagnostic performance can be cost-efficient, patient friendly, and economically accessible.
In Osny, near Pontoise in the Paris region, the Sainte-Marie Imaging Centre has strengthened its partnership1 with Siemens in order to deal with several challenges. As in many industrialized countries with an aging population, these include handling increasing demand for treatment and imaging, reducing waiting times for appointments, limiting scan times to enable profitability and efficiency, but also for the comfort and health of patients, and maintaining high diagnostic quality while reducing the costs of buying, installing, and operating equipment.
The economic benefits of the arrival of SOMATOM Perspective are many. Installed in just one day, it is a small, very compact, ultra-light machine, which can fit into a room with a floor space of less than 20 square meters, without requiring floor reinforcements or air conditioning. The scanner itself is already incredibly efficient and the exclusive eMode contributes to financial efficiency with every scan. An automated software solution makes efficiency easy: eMode automatically sets the parameters for the most efficient scan. A scan analysis is made in real-time and the system automatically fine-tuned to provide a balanced scan, while reducing wear and tear on the system. Additionally, with a Siemens service contract, customers can take full advantage of eMode benefits. The system will be analyzed every 12 months to determine the customer’s eMode usage. If eMode was used in more than 80 percent of scans, the site is entitled to choose one of the valuable eMode service benefits. These include the syngo® Remote Trainer, preventive maintenance outside of prime working hours, one-on-one assistance with syngo Remote Assist, or revaluation of the maintenance contract price with eMode service contract adjustments.
For patients, waiting times got considerably shorter: 48 hours instead of three weeks or longer, thanks to the system’s high throughput capacity. Over a period of six weeks, it was possible to scan 800 patients, covering the whole range of pathologies, such as cancer, pediatric, cardiac, vascular, bone and joint, and brain. Sainte-Marie Medical Imaging Center is combining Sinogram Affirmed Iterative Reconstruction (SAFIRE2), CARE Dose4D, UFC(R) and SureView for dose reduction. Offering ease of use, acquisition speed, image quality, and radiation dose reduction by at least 50 percent, SOMATOM Perspective meets all the expectations of the medical team. And is proving to be a “flagship machine,” designed to meet the everyday requirements of all radiology centers.
The term “partnership” does not imply a legal partnership or joint venture relationship.
In clinical practice, the use of SAFIRE may reduce CT patient dose depending on the clinical task, patient size, anatomical location, and clinical practice. A consultation with a radiologist and a physicist should be made to determine the appropriate dose to obtain diagnostic image quality for the particular clinical task. The following test method was used to determine a 54 to 60% dose reduction when using the SAFIRE reconstruction software. Noise, CT numbers, homogeneity, low-contrast resolution and high contrast resolution were assessed in a Gammex 438 phantom. Low dose data reconstructed with SAFIRE showed the same image quality compared to full dose data based on this test. Data on file.
The outcomes achieved by the Siemens customers described herein were achieved in the customer’s unique setting. Since there is no “typical” hospital and many variables exist (e.g., hospital size, case mix, level of IT adoption), there can be no guarantee that others will achieve the same results.
