Intended Use

S-scan is a Magnetic Resonance (MR) system that produces transversal, sagittal and coronal and oblique cross-section images of the limbs, joints and spinal column. It is intended for imaging portions of the upper limb, including the hand, wrist, forearm, elbow, arm and shoulder, imaging portions of the lower limb, including the foot, ankle, calf, knee, thigh and hip, imaging of the temporomandibular joint and imaging the cervical spine and the lumbar spine sections as portions of the spinal column. S-scan images correspond to the spatial distribution of protons (hydrogen nuclei) that determine magnetic resonance properties and are dependent on the MR parameters, including spin-lattice relaxation time (T1), spin-spin relaxation time (T2), nuclei density, flow velocity and "chemical shift". When interpreted by a medical expert trained in the use of MR equipment, the images can provide diagnostically useful information.

Device Story

S-Scan is a magnetic resonance imaging (MRI) system for musculoskeletal applications. It captures proton density and relaxation signals (T1, T2) to generate cross-sectional images of limbs, joints, and spine. Operated by trained medical professionals in clinical settings. Modifications include improved patient positioning kits, geometric distortion correction, optimized Fast Spin Echo (FSE) parameters, and enhanced streaming acquisition. Includes 'SpeedUp' technique for faster imaging. Output is viewed by radiologists/clinicians to aid diagnosis. Benefits include improved image quality and workflow efficiency through software updates and hardware positioning aids.

Clinical Evidence

Bench testing only. No clinical data provided. Performance improvements verified through technical validation of software and hardware modifications.

Technological Characteristics

Magnetic resonance diagnostic device. System includes patient positioning hardware, coils, and software for image acquisition and processing. Connectivity includes worklist server integration and DICOM-based export. Software-based image reconstruction and geometric distortion correction.

Indications for Use

Indicated for patients requiring diagnostic imaging of limbs, joints, temporomandibular joint, and cervical/lumbar spine sections. Used for visualizing spatial distribution of protons to provide diagnostically useful information when interpreted by trained medical experts.

Regulatory Classification

Identification

A magnetic resonance diagnostic device is intended for general diagnostic use to present images which reflect the spatial distribution and/or magnetic resonance spectra which reflect frequency and distribution of nuclei exhibiting nuclear magnetic resonance. Other physical parameters derived from the images and/or spectra may also be produced. The device includes hydrogen-1 (proton) imaging, sodium-23 imaging, hydrogen-1 spectroscopy, phosphorus-31 spectroscopy, and chemical shift imaging (preserving simultaneous frequency and spatial information).

Special Controls

*Classification.* Class II (special controls). A magnetic resonance imaging disposable kit intended for use with a magnetic resonance diagnostic device only is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 892.9.

#### Device Description

The changes performed on the modified S-scan device, with respect to the cleared version – S-scan K110802 - are due to the improvement of the system performance. These modifications, which do not affect the intended use or alter the fundamental scientific technology of the device, are the following:

- 1. A new step for patient positioning.
- 2. A kit for patient positioning during hip examination using 4-channels lumbar spine coil 17 and 18.
- 3. Geometric distortion correction.
- 4. FSE parameters optimization

.

.

- 5. FSE acceleration and improving.
- 6. FSE sampling frequency management.
- 7. Streaming acquisition performance increasing.
- 8. Configurable send and export of XBONE echoes.
- 9. Environment for the management of the virtual film.
- 10. Data matching for patient coming from a worklist server.

11. SpeedUp technique introduction, cleared via K120748.

- 12. A new software version.

### Dear Ms. Scott:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
