No
The summary lists several software enhancements and features, primarily related to image reconstruction, artifact reduction, and workflow improvements. None of the listed features or the overall device description explicitly mention or imply the use of AI or ML technologies. The focus is on traditional image processing and reconstruction techniques.
No
The device is described as a diagnostic imaging system, used to detect, localize, diagnose, and stage diseases, and to aid in treatment planning, rather than to treat conditions directly.
Yes
The "Intended Use / Indications for Use" section explicitly states that the system is "intended to be utilized by appropriately trained health care professionals to aid in detecting, localizing, diagnosing, staging and restaging of lesions, tumors, disease and organ function for the evaluation of diseases and disorders". It also mentions the "system maintains independent functionality of the CT and PET devices, allowing for single modality CT and / or PET diagnostic imaging."
No
The device is a combined hardware (CT and PET scanners, patient handling system, workstations) and software system, not a software-only medical device. The software is described as a component of the larger hardware system.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body, such as blood, urine, or tissue, to provide information about a person's health.
- Device Function: The Siemens Biograph mCT systems are imaging devices that use X-rays (CT) and radiopharmaceuticals (PET) to create images of the inside of the body. They do not analyze samples taken from the body.
- Intended Use: The intended use clearly states that the system is used to "aid in detecting, localizing, diagnosing, staging and restaging of lesions, tumors, disease and organ function" by producing images. This is a diagnostic imaging function, not an in vitro diagnostic function.
The device is a medical imaging system used for diagnostic purposes, but it does not fall under the definition of an In Vitro Diagnostic device.
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 and restaging 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.

Device Description
The Biograph mCT and mCT Flow PET/CT Scanners are combined multi-slice X-Ray Computed Tomography and Positron Emission Tomography scanners. These systems are designed for whole body oncology, neurology and cardiology examinations. The Biograph mCT systems provide registration and fusion of high-resolution metabolic and anatomic information from the two major components of each system (PET and CT). Additional components of the system include a patient handling system and acquisition and processing workstations with associated software.
