#### Device Description

The E.CAM LSO 311 PET/SPECT system is a dual detector head nuclear camera having the purpose of performing a full range of nuclear medicine procedures, including:

- 1) static, dynamic, whole body, and gated planar single photon procedures;
- 2) dynamic, whole body, and gated single photon emission computed tomography (SPECT) procedures; and
- 3) static, dynamic, whole body, and gated coincidence positron emission tomography (PET) procedures.

The E.CAM LSO 311 system comprises the following components: gantry and patient table mechanical components, computer system (hardware and software), and dual detector heads. Additional features of the system include attenuation correction capabilities and the ability to upgrade existing Siemens E.CAM cameras in the field to the E.CAM LSO 31 l configuration.

# Indications for Use

The Siemens/CPS E.CAM LSO 311 PET/SPECT System is intended to be utilized by appropriately trained health care professionals to image and measure the distribution of injected single photon radiopharmaceuticals and positron emitting radiopharmaceuticals in hismans for use in the determination of various metabolic and physiologic functions within the human body and in the diagnosis of certain disease conditions in various organs, tissues and other anatomical structures.

# Comparison with Predicate Devices

The E.CAM LSO 311 system is essentially a modified and enhanced version of the Siemens IP500 E.CAM gamma camera and E.CAM Coincidence Mode design and similar products from other vendors, which permits the imaging of positron emitting isotopes in coincidence mode in addition to single photon emitters in the single photon mode. In addition, this new PET/SPECT tomograph utilizes many hardware and software components from currently produced CTI PET Systems (CPS) PET scanners such as the ECAT EXACT and ECAT EXACT HR+. The E.CAM LSO 311 system optimizes the clinical usability of coincidence detection imaging, by enhancing the trues count rate and sensitivity performance of the camera, while still retaining optimum single photon capabilities.

# Summaries of Studies

Initial investigation indicates that the CPS E.CAM LSO 311 PET/SPECT System will be capable of performing static, dynamic, whole body and gated planar single photon imaging procedures, as well as single photon emission computed Tomography (SPECT) procedures and positron emission tomography (PET) procedures utilizing a new combination LSO and NaI(TI) crystal detector system developed by CPS.

#### Conclusion

In the opinion of CTI PET Systems, the E.CAM LSO 311 System is substantially equivalent to the currently distributed Siemens IP500 Gamma Camera System and the associated E.CAM coincidence option. We believe the E.CAM LSO 311 is also substantially equivalent to the Siemens/CPS ECAT EXACT and EXACT HR+ PET systems. The E.CAM LSO 311 has the same intended use and has many of the same technological characteristics as those devices. We do not believe the E.CAM LSO 311 System design raises any new safety and effectiveness concerns.
