Intended Use

The NL3000 CereTom is intended to be used for x-ray computed tomography applications for anatomy that can be imaged in the 25cm field of view, primarily head and neck.

Device Story

The NL3000 CereTom is a portable, 8-row, 32cm bore CT scanner. It features a translating gantry that moves over a stationary patient, allowing for imaging in clinical settings. The system includes a solid-state x-ray generator, 3264-element detector array, and a brushless DC servo drive for rotation and translation. It is powered by internal dry sealed batteries or line power. The device is operated via a workstation (Sony Vaio laptop) running third-party CT viewing software. The system provides high-resolution CT images, enabling clinicians to perform diagnostic imaging at the point of care. By allowing the gantry to move while the patient remains still, the device facilitates imaging for patients who may be difficult to transport to a traditional radiology suite, potentially improving clinical workflow and patient management.

Clinical Evidence

Bench testing only. The device was evaluated for compliance with Federal Diagnostic X-ray Performance Standards (21 CFR 1020.30 and 1020.33) and medical electrical equipment safety standards (UL60601-1, IEC 60601-1, EN 60601-1). No clinical data was provided.

Technological Characteristics

8-row, 32cm bore CT system. Components: solid-state x-ray generator, 3264-element solid-state detector array, power slip-ring, brushless DC servo drive. Power: dry sealed batteries/line power. Form factor: mobile translating gantry with 100mm caster wheels. Connectivity: communications link to workstation. Safety: emergency stop, x-ray indicators, interlocks, patient alignment laser. Standards: 21 CFR 1020.30/1020.33, UL60601-1, IEC 60601-1, EN 60601-1.

Indications for Use

Indicated for x-ray computed tomography imaging of anatomy within a 25cm field of view, primarily the head and neck.

Regulatory Classification

Identification

A computed tomography x-ray system is a diagnostic x-ray system intended to produce cross-sectional images of the body by computer reconstruction of x-ray transmission data from the same axial plane taken at different angles. This generic type of device may include signal analysis and display equipment, patient and equipment supports, component parts, and accessories.

Predicate Devices

• Philips Tomoscan M/EG CT (K964890)
• GE LightSpeed Ultra CT (K000300)
• Siemens SOMATOM Plus 4 with sliding Gantry Option (K991600)

NeuroLogica Corporation NL3000 CereTom Computed Tomography System 510(k) Summary

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

### (3) Predicate device:

The legally marketed devices to which substantial equivalencies are being claimed are as follows:

- Philips Tomoscan M/EG CT. This predicate device was cleared under pre-. market Notification K964890.
- . GE LightSpeed Ultra CT. This predicate device was cleared under premarket Notification K000300
- Siemens SOMATOM Plus 4 with sliding Gantry Option. This predicate . device was cleared under pre-market Notification K991600

#### (4) Device Description:

The NL3000 CereTom is a high resolution, 8 row, 32 cm bore, 25cm field of view, Computed Tomography System. The lightweight translating gantry consists of a rotating disk with a solid state x-ray generator, 3264-element solid state detector array, collimator, control computer, communications link, power slip-ring, data acquisition system, reconstruction computer, touch screen LCD display, power system, brushless DC servo drive system (disk rotation), and stepper drive system (translation). The power system consists of dry sealed batteries which provide system power while unplugged from the charging outlet. When plugged into an outlet the system charges the batteries with a line power drain of less than 1300 watts. The work station consists of a Sony Vaio laptop computer. The workstation software consists primarily of a certified off-the-shelf CT viewing system from a third party vendor. In addition the system has the necessary safety features such as emergency stop switch, x-ray indicators, interlocks, patient alignment laser, and 110 percent x-ray timer. It requires very little x-ray power in comparison to large bore systems to obtain equivalent CT image quality. The gantry has retractable 100mm diameter rotating caster wheels so the system can be moved easily to different locations.

#### (5) Intended Use:

The NL3000 CereTom is intended to be used for x-ray computed tomography applications for anatomy that can be imaged in the 25cm field of view, primarily head and neck.

## Comparison of Technological Characteristics with the predicate device: (6)

NeuroLogica Corporation believes that the NL3000 Computed Tomography Noteriogrea Corporated use, is of comparable type in design, material, System, for tto meetidor and is substantially equivalent to the following cleared predicate devices: Philips Tomoscan M/EG (also named ANATOM 2009, ref: predicate dovices: 1 milling ref: K000300, and Siemens SOMATOM Plus4 with Translating Gantry option, ref: K991600

- Material: The CereTom uses similar material to the above listed o scanners such as solid state detectors, x-ray generator, slip ring, data acquisition ICs, rotational bearing, and motion control systems. It also uses batteries and wheels similar in material to the Tomoscan M/EG.
- Design: The CereTom is similar in general design principle to all of o the above listed CT systems. Specifically it is similar to the 1) Lightspeed in multi-slice (8 Row) image quality, 2) Tomoscan M/EG and Somatom Plus 4 as to the translating gantry (patient stays still while the gantry translates), and 3) Tomoscan M/EG as to batteries and wheels.

# 7) General Safety and Effectiveness Concerns:

All components of the NL3000 CereTom system subject to Federal Diagnostic An component Performance Standard and applicable regulations of 21 CFR Part 1020.30 and 1020.33 are certified to meet those requirements.
