MRI requires a very uniform magnetic field within a few ppm. NMR is the only magnetic measurement technology that can provide magnetic field maps with that level of precision. In research and development, manufacturing processes, and installation adjustments at MRI manufacturers, it is necessary to repeatedly measure magnetic field maps and perform shimming (correction of magnetic field inhomogeneity), making the accuracy of measurements and reduction of required time extremely important. The NFC2046 magnetic field camera is an improved successor to the MFC3045 magnetic field camera, which revolutionized magnetic field mapping for MRI magnets in the 1990s. The conventional MFC3045 was a groundbreaking product that reduced the time required for magnetic field mapping from several hours to several minutes, with positioning errors below 1mm and levels of human error and drift error that could be ignored. The MFC2046 is a new product that inherits the advantages of the conventional MFC3045 while incorporating the following improvements: - Expanded the upper limit of the magnetic field strength that can be mapped from 7T to 30T - Reduced the minimum bore diameter that can be mapped from 220mm to 40mm - Increased the number of NMR probes that can be mounted on the probe array from 32 to 255

To accurately and precisely create multiple pulses with a long time delay (delay) at a resolution of picoseconds (ps) and to measure that time difference accurately and precisely, general equipment cannot achieve the necessary precision or resolution at all. - The T560 delay/pulse generator from Highland Technology can set the delay time and pulse width individually for 4 channels in increments of 10 ps, up to a maximum of 10 seconds. - The MCS8A multi-stop TDC/TOF from FAST ComTec can detect the time difference between the START signal and 8 input STOP signals in increments of 80 ps, up to a maximum of 8.3 days.

NMR (Nuclear Magnetic Resonance) is the most precise technology for measuring magnetic fields, and the PT2026 is the most accurate NMR magnetometer on the market. - Under optimal conditions, it can achieve high precision of less than 10 ppb. - It features high magnetic field compatibility, robustness in inhomogeneous magnetic fields, a measurement speed of 33 Hz, and improved search time. - Designed with the latest high-frequency technology and computer technology, the NMR magnetometer can explore many new applications. There are three types of pulse wave probes for measuring magnetic fields, which can flexibly accommodate various measurement ranges. - It can be connected with just one RF cable, making plug insertion and removal easy. - The 1326 probe incorporates a 3-axis Hall element probe, which accelerates the search for NMR signals. - The 1426 probe has a remote passive measurement head that fits into narrow gaps, allowing it to operate in high-radiation environments without damaging electronic components. - The 1526 probe features a remote active measurement head that fits into narrow gaps, improving the S/N ratio by processing NMR signals locally and allowing for longer cable lengths.
