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 and imaging portions of the spinal column, including the cervical and lumbo-sacral sections.

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.

The indications for use of the S-scan system, as described in its labeling, are the same as those of the unmodified S-scan system cleared via K063207.

The changes performed on the modified S-scan device, with respect to the cleared version - S-scan K063207 -, are due to the improvement of the system performance. These modifications, that do not affect the intended use or alter the fundamental scientific technology of the device, are the following:

• 1. A device that locks the patient table in the current position, unless the user disconnects the coil cable.
• 2. A limb protection for patient table.
• 3. Modified pulse sequences.
• 4. A new software release.

The provided text is a 510(k) summary for the S-scan System, a Magnetic Resonance Imaging (MRI) device. It details modifications to an existing device (K063207) and compares its technological characteristics to several predicate devices.

However, the document does not contain any information regarding specific acceptance criteria, a study proving the device meets these criteria, or any performance metrics from such a study.

The submission focuses on establishing substantial equivalence to previously cleared devices based on technological characteristics and intended use, rather than presenting new performance study data for approval. Therefore, I cannot complete the requested tables and information based on the input provided.

Here's a breakdown of what is present in the document, and what is not:

What is present:

• Device Name: S-scan System, Nuclear Magnetic Resonance Imaging
• Intended Use: Produces transversal, sagittal, coronal, and oblique cross-section images of limbs, joints, and the spinal column for diagnostic information when interpreted by a medical expert.
• Predicate Devices: S-scan (K063207), G-scan (K042236), Siemens Magnetom C! (K043030), Esaote Dynamic MRI Software (K061429), Siemens Syngo Multimodality Workstation (K010938).
• Modifications to the S-scan (K063207):
  • Device that locks the patient table.
  • Limb protection for the patient table.
  • Modified pulse sequences.
  • A new software release.
• Technological Characteristics Comparison: Detailed lists of pulse sequences and their parameters for the modified S-scan compared to the predicate S-scan (K063207), G-scan (K042236), and Siemens Magnetom C! (K043030). Also details image processing functions, networking functions, system access management, and accessories compared to predicate devices.

What is NOT present (and therefore cannot be provided in the requested format):

• Table of Acceptance Criteria and Reported Device Performance: No acceptance criteria or performance metrics are stated. The submission relies on demonstrating substantial equivalence to predicates, implying that if the technological characteristics and intended use are similar, the performance is also considered similar.
• Study details (Sample size, data provenance, number of experts, adjudication method, MRMC, standalone performance, ground truth type, training set size, ground truth for training set): The document does not describe any specific performance study conducted to assess the diagnostic accuracy or clinical effectiveness of the modified S-scan device. The "study" here is essentially a technical comparison for substantial equivalence.

In summary, the provided 510(k) summary focuses on demonstrating that the modified S-scan device is substantially equivalent to existing cleared devices based on its technological characteristics and intended use, rather than providing the results of a clinical performance study with specific acceptance criteria.
