Somatom confidence scanner

Manufactured by Siemens

Sourced in Germany

The SOMATOM Confidence is a computed tomography (CT) scanner produced by Siemens. It is designed to acquire high-quality 3D images of the body's internal structures. The scanner uses advanced imaging technology to generate detailed cross-sectional images that can be used for diagnostic purposes.

Dual-Energy CT Imaging for Proton Therapy

In this study, 27 neuro-oncological patients were included. The patient characteristics are listed in Table 1. The patients were all treated with proton therapy in a clinical routine workflow, with a treatment plan created on a planning SECT scan (pSECT). During their treatment, they received weekly repeat-CTs, which were acquired in both SECT (reSECT) and DECT mode. For this study, the DECT scan from the first repeat-CT was used, typically acquired after 1 week of treatment. Institutional Review Board approval was granted (W 21 03 00100).
The DECT scans were acquired in either Dual Source mode with a Siemens SOMATOM Drive scanner (Siemens Healthineers, Forchheim, Germany; 80/Sn140 kVp – Sn: 0.4 mm tin filter; simultaneous acquisition; field-of-view of 330 mm) for 15 patients, or in Dual Spiral mode on a Siemens SOMATOM Confidence scanner (80/140 kVp; sequential acquisition; field-of-view of 350 mm) for 12 patients. The DECT images were reconstructed applying a Qr40 kernel with beam hardening correction for bone and iterative reconstruction—ADMIRE (Drive) or SAFIRE (Confidence)—at strength level 3. The SECT scans were acquired at 120 kVp and were reconstructed with same reconstruction algorithm, in general the settings for the DECT scans were based on the clinical settings for the SECT scans.

Multi-Cancer CT Imaging Protocol

Computed tomography images from 105 different patients were included: 30 patients with lung, 30 patients with breast, and 35 patients with prostate cancer. All the CT scans were performed with a 64-slice, single-source, flat-table SOMATOM Confidence scanner (Siemens Healthineers). The characteristics of the CT scanning protocols are described in the Appendix. The CT scans of patients with lung cancer were acquired in the supine position with the stereotactic body RT Conchest Supra (Lorca Marin S.A., Murcia, Spain) immobilization system and respiratory control using the RGSC (Respiratory Gating for Scanners) system (Varian Medical Systems, Palo Alto, CA). For the contouring of OARs, the “Average” series was used. Patients with breast cancer were positioned with their arms abducted and were immobilized with the same system as those with lung cancer. The CT scan was performed with deep breaths and with respiratory control for all left breasts, as well as for right breasts requiring radiation of the ganglia regions, provided the patient could complete it. In total, there were 15 patients with the right breast affected (3 breath hold and 12 free breathing) and 15 patients with the left breast affected (12 breath hold and 3 free breathing). All CT scans were performed with the patient in the supine position.

3D-Printed Phantom Brachytherapy Protocol

In Fig. 1 the experimental workflow of the activities performed to realize IVD for the 3D printed phantom can be found. All data analysis was done using Matlab 2019b (Natick, MA).
In preparation for the treatment delivery, a CT acquisition of the head phantom with holder, inserted brachytherapy needles and markers had to be obtained. The CT was made using a SIEMENS SOMATOM Confidence scanner, using a slice thickness of 1 mm for the acquisition. The lead ball-shaped markers (The Suremark Company, Simi Valley) have a diameter of 2 mm and were placed on the phantom so that their projection would be visible on the IP image.
A treatment plan was created using the treatment planning system (TPS) BrachyVision (version 16, Varian Medical Systems, Palo Alto) based on CT images of the phantom. This resulted in a plan where all 3 catheters consisted of 20 dwell positions with an interdwell distance of 2 mm and a dwell time ranging from 0.3 to 4.0 seconds.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
