The summary describes standard image reconstruction and processing techniques for CT and PET imaging, with no mention of AI or ML algorithms. The software updates listed are related to workflow, performance, and specific imaging protocols, not AI/ML capabilities.
No.
The device is used for diagnostic imaging and assessment, not for direct treatment or therapy.
Yes
The "Intended Use / Indications for Use" section explicitly states that the systems are intended to "aid in detecting, localizing, diagnosing, staging and restaging of lesions, tumors, disease and organ function for the evaluation of diseases and disorders." This directly indicates its role as a diagnostic device.
No
The device description explicitly states that the system includes hardware components such as X-Ray Computed Tomography and Positron Emission Tomography scanners, a patient handling system, and acquisition and processing workstations, in addition to the software.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples such as blood, urine, or tissue that have been taken from the human body to detect diseases or other conditions.
- Device Function: The Siemens mCT systems are imaging devices (CT and PET scanners) that produce images of the inside of the body using X-rays and radiopharmaceuticals. They do not analyze samples taken from the body.
- Intended Use: The intended use describes the system as aiding in detecting, localizing, diagnosing, staging, and restaging of lesions, tumors, disease, and organ function through imaging. It also mentions use in radiotherapy treatment planning and interventional radiology procedures, all of which are based on imaging.
- Device Description: The description focuses on the hardware (scanners, workstations) and software for image acquisition, reconstruction, and evaluation.
The device is a medical imaging system used for diagnostic purposes, but it does so by generating images of the body directly, not by analyzing samples in vitro.
N/A
Intended Use / Indications for Use
The Siemens Biograph mCT systems are combined X-Ray Computed Tomography (CT) and Positron Emission Tomography (PET) scanners that provide registration and fusion of high resolution physiologic and anatomic information.
The CT component produces cross-sectional images of the body by computer reconstruction of X-Ray transmission data from either the same axial plane taken at different angles or spiral planes taken at different angles. The PET subsystem images and measures the distribution of PET radiopharmaceuticals in humans for the purpose of determining various metabolic (molecular) and physiologic functions within the human body and utilizes the CT for fast attenuation correction maps for PET studies and precise anatomical reference for the fused PET and CT images.
The system maintains independent functionality of the CT and PET devices, allowing for single modality CT and / or PET diagnostic imaging.
These systems are intended to be utilized by appropriately trained health care professionals to aid in detecting, localizing, diagnosing, staging of lesions, tumors, disease and organ function for the evaluation of diseases and disorders such as, but not limited to, cardiovascular disease, neurological disorders and cancer. The images produced by the system can also be used by the physician to aid in radiotherapy treatment planning and interventional radiology procedures.
This CT system can be used for low dose lung cancer screening in high risk populations. * As defined by professional medical societies. Please refer to clinical literature, including the results of the National Lung Screening Trial (N Engl J Med 2011; 365:395-409) and subsequent literature, for further information.
