Intended Use

The Forte Gamma Camera System is intended to produce images depicting the anatomical distributions of single photon and positron emitting radioisotopes within the human body for interpretation by medical personnel.

Device Story

Forte Gamma Camera System is an emission computed tomography system for nuclear medicine. It utilizes single or dual detectors to capture radioisotope emissions from patients sitting, standing, or lying down. The system includes a gantry, patient table, and remote controller. It performs static, dynamic, gated, total body, and SPECT studies. The device transforms raw acquisition data into images for medical personnel interpretation. The system features the JETStream Java-based GUI, replacing the legacy DOS interface, and includes a touch-screen display for patient positioning and count rate monitoring. It supports DICOM 3.0 for data export and worklist management. The system enables concurrent multi-energy/multi-isotope imaging. Clinicians use the output images to assess anatomical distributions of radioisotopes, aiding in diagnostic decision-making across various nuclear medicine procedures like bone, lung, renal, and thyroid scans.

Clinical Evidence

No clinical data provided. Substantial equivalence is based on technological comparison and system performance evaluation.

Technological Characteristics

Emission computed tomography system; dual-detector gantry; Java-based JETStream GUI; DICOM 3.0 compliant; touch-screen interface for P-scope and gantry display; supports single/dual detector configurations for SPECT, planar, and coincidence imaging.

Indications for Use

Indicated for imaging anatomical distributions of single photon and positron emitting radioisotopes in patients requiring nuclear medicine studies, including SPECT, static, dynamic, gated, total body, and coincidence imaging. No specific age or gender contraindications provided.

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.

F. Device Description:

for interpretation by medical personnel.

The modified Forte Gamma Camera System offers all the features of the existing Forte Gamma Camera System (K982911) while expanding the Concurrent Imaging feature for Multi-Energy/Multi-Isotope Imaging and the addition of DICOM to the acquisition system. The basic underlying algorithms for concurrent imaging remain the same. Software modifications to the Multi-Energy/Multi-Isotope application extend the current functionality to include acquisition of more image events simultaneously. Acquisition data can be exported to the Pegasys or any other processing station via DICOM by translating image data from the native XML format to a DICOM 3.0 complaint format. The addition of DICOM to the acquisition software will enhance workflow by providing DICOM Worklist and the capability to import patient information for scheduling purposes. The DOS-based user interface in Atlas acquisition system (predicate) is replaced by a Java based graphical user interface JETStream™. The Java graphical user interface provides a modern graphics presentation as opposed to the DOS text based interface of the predicate. In addition, P-scope (patient positioning/count rate) and gantry display information are now available on a touch screen for easy accessibility.

The Forte is designed to provide extended imaging functionality relative to a ring style gantry. The Forte is designed for single or dual detector nuclear imaging accommodating a broad range of emission computed tomography (ECT) studies. The device includes a gantry frame, display panel, two detectors, a collimator storage structure with an acquisition computer unit, a patient imaging table, and a remote hand controller. The gantry is "open" so that a high degree of imaging flexibility is available to image patients sitting, standing or lying down, with or without the included patient imaging table. The patient imaging tables are mechanized to allow for patient loading access and then raised to

{1}------------------------------------------------

an imaging height. The imaging pallet includes removable arm, leg, breast, and headrest supports for patient positioning during studies that require support.

The Forte is designed to allow acquisition of a broad range of imaging studies using single or dual detectors. When using either a single detector or dual detectors placed in a relative 90-degree or relative 180-degree positions (as study appropriate), Forte can be used to perform static, dynamic, gated, total body, circular-orbit and non-circular orbit SPECT studies, coincidence studies, gated SPECT (circular and non-circular) studies, computerprogrammed protocol strings, and reference scans (dual detectors only). SPECT and total body acquisitions are routinely acquired with two detectors. There are some planar procedures such as bone statics and lung scan that also use two detectors. There are many additional nuclear medicine procedures that only use one detector at a time. These single detector procedures are typically renal, gastric emptying, hepatobiliary, flow studies, GI bleed, thyroid, and delayed static views.

### G. Technological Comparison:

The modified Forte™ Gamma Camera System and existing Forte Gamma Camera System have identical intended use and indications for use. The modified Forte and the existing Forte are technologically equivalent. They have the same main mechanical and electrical components. All the features provided on the existing Forte are provided on the modified Forte. Acquisition software changes consist of: replacement of the predicate Atlas with the JETStream, the expanded feature of Concurrent Multi-Energy/Multi-Isotope Imaging, and DICOM Export/Worklist. In addition, the P-scope (patient positioning/count rate) and gantry display information shall be available on a touch screen.

#### H. Conclusion

The modified Forte™ Gamma Camera System is substantially equivalent to the predicate device Forte based upon identical indications for use, technological comparison and overall system performance.
