MITS-TT-LF
MITS - TableTop - Low Field
The Low-field MITS-TableTop (MITS-TT-LF) is a MITS-TT designed for lower MRI fields, such as 0.55T. It provides the same features and applications as the high-field version: a compact and easy-to-use radiofrequency (RF) induced field generator optimized for scaling and validating transfer function models (deposited power, heating or terminal voltage) of active implantable medical devices (AIMD) inside low and high permittivity media.
The MITS-TT-LF can operate at two different frequencies. The default target MRI fields are 0.55T and 1.0T, with operating frequencies of 23.4 MHz and 42.6 MHz. Custom frequencies, or combinations of fields (e.g. 0.55 / 1.5T or 0.55 / 3.0T) are available upon request.
Medical Implant Test System – TableTop Low-Field (MITS-TT-LF).
The system fully complies with all relevant test specifications (ISO 10974, ASTM F2182, PC76, and FDA guidance).
Validation is possible with minimal remounting of the AIMD by adjusting phase and amplitude between the two electrode pairs, thereby varying the induced field following the Test Field Diversity method. The test system only requires low power (~50 dBm) and will be shipped calibrated.
MITS-TT-LF comprises two units (high and low permittivity media). The two pairs of orthogonal electrodes are integrated in the phantom. The dual-band source, amplifiers and control computer are integrated in a small rack.
