Intended Use

The ECAT LSO PET/CT 16 tomographic scanner system is a combined positron emission tomography (PET) and X-ray computed tomography (CT) scanner. The ECAT LSO PET/CT 16 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. (*spiral planes: the axial planes resulted from the continuous rotation of detectors and x-ray tube and the simultaneous translation of the patient.)

Device Story

Combined PET/CT scanner; utilizes PET component from predicate and Siemens P30 SOMATOM SENSATION CT component (24-row detectors, 16-slice capability). PET acquires data in 3D mode; CT provides attenuation correction maps and anatomical reference. PET and CT components housed in unified gantry; patient handling system modified for dual scan coverage. Operated by trained healthcare professionals in clinical settings. System produces fused PET/CT images for detailed anatomic and metabolic assessment. Benefits include faster, higher-quality CT acquisitions, improved patient throughput, and precise anatomical localization of metabolic activity.

Clinical Evidence

Bench testing only. System tested by manufacturer to meet predetermined performance requirements and compliance with IEC 60601-1, UL 187, and 21 CFR 1020.30/1020.33 standards.

Technological Characteristics

Dual-modality PET/CT scanner. PET component: 3D acquisition. CT component: Siemens P30 SOMATOM SENSATION, 24-row detectors, 16-slice capability. Energy source: X-ray and positron-emitting radiopharmaceuticals. Connectivity: Integrated workstation. Standards: IEC 60601-1, UL 187, 21 CFR 1020.30/1020.33.

Indications for Use

Indicated for use by trained healthcare professionals to image/measure distribution of injected positron-emitting radiopharmaceuticals in humans to determine metabolic/physiologic functions and to produce cross-sectional images via X-ray transmission data reconstruction. Used for whole-body oncology imaging.

Regulatory Classification

Identification

An emission computed tomography system is a device intended to detect the location and distribution of gamma ray- and positron-emitting radionuclides in the body and produce cross-sectional images through computer reconstruction of the data. This generic type of device may include signal analysis and display equipment, patient and equipment supports, radionuclide anatomical markers, component parts, and accessories.

ECAT LSO PET/CT 16 Combination Positron Emission Tomography (PET) and X-Ray Computed Tomography (CT) Emission Computed Tomography System per 21 CFR 892.1200

#### Marketed Devices to Which Equivalence is Claimed

#### Device Description and Comparison to the Unmodified Device

The ECAT LSO PET/CT 16 is a combined positron emission tomography (PET) and X-ray computed tomography (CT) scanner. This dual modality tomograph is a modified version of the ECAT LSO PET/CT (K013504) and will utilize the same PET component as the ECAT LSO PET/CT scanner. However, in place of the Siemens P10 SOMATOM EMOTION CT component that uses a single or dual row of X-Ray detectors, the ECAT LSO PET/CT 16 will be configured with the Siemens P30 SOMATOM SENSATION CT, utilizing 24 rows of X-Ray detectors and having the capability to acquire 16 slices of X-Ray data simultaneously. As with the unmodified system, 2D PET acquisition septa and the PET transmission sources are not incorporated in the modified ECAT LSO PET/CT. PET emission data is acquired only in 3D mode and PET attenuation correction map data are obtained from the CT. The PET and CT components are contained within a unified housing similar to the original ECAT LSO PET/CT to create an integrated, PET, CT, and combined PET/CT, tomographic imaging system.

The ECAT LSO PET/CT 16 gantry structure, patient handling system (PHS), advanced computational system (ACS 3), workstation and software will be similar to the ECAT LSO PET/CT with only minor modifications. The gantry's unified housing has been modified cosmetically and enlarged to accommodate the increased size of the SOMATOM P30 CT gantry. In addition, the patient handling system (PHS) has been modified to ensure adequate

dual scan coverage for PET and CT patient scanning, with the increased axial depth of the new SOMATOM P30 CT gantry. The high performance Siemens P30 SOMATOM SENSATION CT with 16 slice capability provides for faster and higher quality CT acquisitions but does not otherwise affect performance of the ECAT LSO PET/CT 16.

The ECAT LSO PET/CT 16 scanner is intended for use primarily as a clinical, whole-body oncology machine with high-end spiral CT performance and fast patient-throughput clinical PET performance. As on the original system, 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 16 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.

The purpose of introducing this modified ECAT LSO PET/CT 16 system is to offer a combined PET and CT tomograph having very high CT performance with the fast throughput of the ECAT ACCEL PET, as a higher performance alternative to the presently distributed ECAT LSO PET/CT system.

#### Intended Use

The CPS ECAT LSO PET/CT 16 system is a combined positron emission tomography (PET) and Xray computed tomography (CT) scanner. This 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.

(*spiral planes: the axial planes resulted from the continuous rotation of detectors and x-ray tube and the simultaneous translation of the patient.)

#### Safety and Effectiveness

The CPS ECAT LSO PET/CT 16 system has been designed to comply with applicable industry safety standards for this type of medical equipment including the international standard IEC 60601-1, General Requirements for the Safety Electrical Medical Equipment and UL 187, the X-Ray Equipment Standard for Safety. The CT component has been tested and meets the requirements of the applicable US Federal Performance Standards and regulations of 21CFR 1020.30 and 1020.33. The PET component is unmodified from the previously cleared ECAT LSO PET/CT (K013504). The combined PET/CT system has been tested by CPS and found to meet its predetermined performance requirements.

# Substantial Equivalence Determination

In the opinion of CPS, the ECAT LSO PET/CT 16 system utilizes the same scientific technology as the unmodified ECAT LSO PET/CT system and raises no new questions with regard to its safety and effectiveness. Therefore, we believe the modified ECAT LSO PET/CT 16 is substantially equivalent to the unmodified ECAT LSO PET/CT with respect to design, material and composition, energy source, and radiation safety characteristics.
