Intended Use

The CPS/Siemens ECAT Vision 3000 and Vision 5000 PET systems are positron emission tomography (PET) scanners that are intended to be utilized by appropriately trained health care professionals to image and measure the distribution of injected positron emitting radiopharmaceuticals in humans for the purpose of determining various metabolic and physiologic functions within the human body.

Device Story

ECAT Vision 3000 (3-head) and 5000 (5-head) are PET scanners using rotating flat panel detector heads and LSO crystal technology. Device acquires PET data via coincidence point source transmission scanning; processes data through ACS III system; reconstructs images using FOREJ rebinning and 2D Attenuation Normalization Weighted OSEM (ANW-OSEM) algorithms. Operated by trained healthcare professionals in clinical settings. System includes patient handling system (max weight 182 kg). Operating console runs Siemens Syngo software on Windows 2000/NT environment for acquisition, display, diagnostic, application, archival, and retrieval. Output consists of cross-sectional images used by clinicians to determine metabolic and physiologic functions. Benefits include improved visualization and diagnostic support for oncology applications.

Clinical Evidence

No clinical data provided; substantial equivalence is based on technological characteristics and design similarities to legally marketed predicate devices.

Technological Characteristics

PET scanner with 3 (Vision 3000) or 5 (Vision 5000) rotating flat panel detector heads. Uses LSO crystal detector technology. Includes patient handling system (max 182 kg). ACS III acquisition system. Reconstruction via dedicated computer. Connectivity: networked console running Siemens Syngo software on Windows 2000/NT. Software includes acquisition, display, and archival tools.

Indications for Use

Indicated for use by trained healthcare professionals to detect location and distribution of injected positron-emitting radionuclides in humans and produce cross-sectional images via computer reconstruction for metabolic and physiologic function assessment.

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.

#### Device Description

The ECAT Vision 3000 and Vision 5000 are new positron emission tomography (PET) scanner systems. The ECAT Vision series PET scanners utilize rotating flat panel detector heads, LSO crystal detector technology and coincidence point source transmission scan capability. The ECAT Vision series scanners are produced and marketed under two distinct models, the ECAT Vision 3000 and the ECAT Vision 5000. The two models of the ECAT Vision are configured with either: 1) three detector heads in the ECAT Vision 3000, or 2) five detector heads in the ECAT Vision 5000.

A Patient Handling System (PHS) is provided with the Vision series scanners, which is a slightly modified version of the PHS included with the CPS ECAT EXACT series PET scanners (K962797). Vertical bed travel, horizontal scanning range and all other PHS operating characteristics are the same for the PHS provided with the Vision series scanners as those of the PHS provided with the ECAT EXACT series scanners. The maximum patient weight specification for the Vision series PHS, is 182 kg (400 lbs).

The acquisition computer system is an ACS III system, similar to that used for the ECAT PET/CT system (K002715). Image reconstruction for the ECAT Vision scanners is performed using a dedicated reconstruction computer. The reconstruction algorithm is FOREJ rebinning and 2D

Attenuation Normalization Weighted OSEM (ANW-OSEM). The reconstruction system interfaces with the acquisition raid disk system for access to the basic acquired data.

The operating console computer is an updated version of the existing ECAT PET/CT operating console. The console runs Siemens Syngo software, with CPS ECAT PET acquisition and application software overlaying the Siemens software. This computer is based on an Intel Pentium system running Microsoft's Windows 2000, or later, operating system. Operating in a syngo-based, NT environment, the ECAT Vision operating software provides acquisition, display, diagnostic, application, system, archival, and retrieval support capabilities. Initially, whole-body oncology applications and visualization tools are being provided.

## Indications for Use

The CPS/Siemens ECAT Vision 3000 and Vision 5000 PET systems are positron emission tomography (PET) scanners that are intended to be utilized by appropriately trained health care professionals to image and measure the distribution of injected positron emitting radiopharmaceuticals in humans for the purpose of determining various metabolic and physiologic functions within the human body.

## Comparison with Predicate Devices

The ECAT Vision series PET scanners leverage much of the already proven technology, as well as many components and features of currently produced CPS tomographic systems. The flat panel detectors, LSO crystal detector technology, and coincidence point source transmission scanning design concepts were borrowed from the E.CAM LSO 311 PET/SPECT system (K981027). The patient handling system (PHS) provided with ECAT Vision scanners is a slightly modified version of the PHS used on the CPS ECAT EXACT and ECAT EXACT HR+ PET systems (K962797). The Advanced Computational System (ACS III), used to store and process acquired PET data into sinograms, as well as the reconstruction computer, control console, and the ECAT PET/syngo software are updated versions of those components used in the ECAT PET/CT system (K002715).
