dynamic Contrast Harmonic Imaging (dCHI)

Compared with conventional phase inversion methods, Hitachi's dynamic Contrast Harmonic Imaging allows the modulation of the phase and transmitted frequency range between pulses. Advantages include significantly improved lateral and contrast resolution, without compromising axial resolution. Frequency modulation provides greater sensitivity at depth, compared with conventional harmonic imaging.

MC-MTI is an accumulation mode that provides extremely detailed micro-vessel morphology visualisation, dramatically improving tumour characterisation. Flash-replenishment sequences can be customised for each examination. 

Time-Intensity curves can be generated from stored clips to display contrast agent enhancement over time, within multiple selectable ROIs. Parameters, such as time-to-peak and amplitude of enhancement, can be derived using a best-fit analysis - and all data can be exported to Excel files for further off-line analysis.
