TDS-B1: Probe System for MRI B1 Field Measurements

The TDS-B1 system was jointly developed with our Z43 partner organization Schmid & Partner Engineering AG (SPEAG) to non-disturbingly and traceably measure the radio frequency (RF) magnetic field (B1) inside magnetic resonance imaging (MRI) systems with high-precision.

TDS-B1 System integrated in the DUAL-CYL-TFD for Test Field Diversity in MITS1.5.


Application	General RF transmit coils evaluations for design, verification and validation Measurement of the incident field inside the MITS systems in order to monitor and adjust the desired amplitude and phase excitations in the TFD phantom (see TFD System)
Frequency Range	10 – 200 MHz
Dynamic Range	120 dB @ 1 Hz resolution bandwidth 100 μA/m–10 A/m @ 100 MHz
Components	2x H1TDSx/MRI (Time-Domain Sensor magnetic field probes) 2x 1RU1TDS (TDS Standalone Remote Unit) Dual channel oscilloscope Laptop TDS-B1 control and evaluation software
TDSB1 Software	Calibration and measurement modes Import/export functionality (load/save current calibration) Time-domain signal scope display (MRI pulse-train view) Polarization display (polarization field view including handedness) API for integration in automated test systems DASY-AIMD interface for TFD
Training	See our training video or request a demonstration at our laboratory in Zurich
