Elixbo PM545 is indicated for use as magnetic resonance diagnostic device that produces axial, sagittal, coronal and oblique cross sectional images, and that displays the anatomical and pathological information of the head, body, or extremities. When interpreted by a trained physician, these images yield information that can be useful in determining a diagnosis.
The proposed device, Elixbo PM545, is a Magnetic Resonance Imaging System that utilizes a 0.45 Tesla permanent magnet in an open gantry design. It's indicated for use as magnetic resonance diagnostic devices (MRDD) that produce transverse, sagittal, coronal and oblique cross sectional images, and that display the internal structure and/or function of the head, body, or extremities. These images when interpreted by a trained physician vield information that may assist in diagnosis. The MRI system is composed of magnet, gradient & shimming system, RF system, spectrometer, temperature controller, patient table system, isolation transformer, respiratory gating unit, chiller and control system. The system software, Prospect, based on Windows® XP professional operating system is an interactive program with user friendly interface. The proposed device includes twelve receiving coils which are Head Coil, Neck Coil, Knee Coil, Shoulder Coil, Wrist Coil, Breast Coil, Ankle Coil, Body Coil (14"), Body Coil (17"), Body Coil (20"), General Purpose Coil (6"), and General Purpose Coil (9").
The provided document describes the safety and effectiveness information for the Elixbo PM545 Magnetic Resonance Imaging System, submitted as a 510(k) premarket notification. This submission indicates that the device's performance was evaluated through non-clinical bench tests and a comparison to a predicate device, rather than a clinical study with specific acceptance criteria for diagnostic performance metrics like sensitivity or specificity.
1. Table of Acceptance Criteria and Reported Device Performance:
The acceptance criteria for the Elixbo PM545 are primarily based on compliance with international standards for medical electrical equipment and a determination of substantial equivalence (SE) to a legally marketed predicate device (mStar MPF4500, K073457). The "device performance" in this context refers to its ability to meet these technical standards and operate comparably to the predicate device.
