The CPS/Siemens ECAT LSO PET/CT system is a combined positron emission tomography (PET) and X-ray computed tomography (CT) scanner. The ECAT LSO PET/CT scanner is intended to be utilized by appropriately trained health care professionals to 1) image and measure the distribution of injected positron emitting radiopharmaceuticals in humans for the purpose of determining various metabolic (molecular) and physiologic functions within the human body; and 2) to produce 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 and the CT functions of this system can also be used in combination to provide high resolution, noise free CT attenuation correction maps for PET images and, additionally, utilized to produce fused CT and PET images, providing detailed anatomic and metabolic function information in a single image.

Device Story

Combined PET/CT scanner; utilizes LSO crystal block detectors for PET and Siemens SOMATOM EMOTION CT component for X-ray transmission data. Inputs: positron-emitting radiopharmaceuticals (PET) and X-ray transmission data (CT). Transforms inputs via computer reconstruction to produce cross-sectional images; CT data provides attenuation correction maps for PET. Used in clinical settings by trained healthcare professionals. Output: fused PET/CT images providing anatomical and metabolic information. Benefits: enables precise anatomical localization of metabolic activity; facilitates noise-free attenuation correction; supports standard diagnostic protocols.

Clinical Evidence

No clinical data provided; substantial equivalence based on technological comparison and bench-level design specifications.

Technological Characteristics

Dual-modality imaging system; PET component uses 144 LSO crystal block detectors; CT component uses Siemens SOMATOM EMOTION (single or dual-slice) X-ray scanner. System includes gantry, patient handling system, and computational workstations. Connectivity supports integrated PET/CT image fusion and attenuation correction. Software performs computer reconstruction of transmission data.

Indications for Use

Indicated for humans requiring metabolic/physiologic imaging via injected positron-emitting radiopharmaceuticals and cross-sectional X-ray imaging. Used by trained healthcare professionals for whole-body oncology and diagnostic imaging.

Regulatory Classification

Identification

The ECAT LSO PET/CT scanner is intended for use primarily as a clinical, whole-body oncology machine with mid-range spiral CT performance and fast patient-throughput clinical PET performance. The CT component will also enhance PET scans by allowing fast, essentially noise-free attenuation correction for PET studies, and by providing precise anatomical reference through fused PET and CT images. In addition, the ECAT LSO PET/CT will retain mechanical isolation and independent functionality of the PET and CT scanning systems, thereby allowing for most standard CT and PET clinical diagnostic protocols to be available on the PET/CT system.

#### Indications for Use

The CPS/Siemens ECAT PET/CT system is a combined positron emission tomography (PET) and Xray computed tomography (CT) scanner. The PET/CT scanner is intended to be utilized by appropriately trained health care professionals to 1) image and measure the distribution of injected position emitting radiopharmaceuticals in humans for the purpose of determining various metabolic (molecular) and physiologic functions within the human body; and 2) to produce 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 and the CT functions of this system can also be used in combination to provide high resolution, noise free CT attenuation correction maps for PET images and, additionally, utilized to produce fused CT and PET images, providing detailed anatomic and metabolic function information in a single image.
