In assessing the safety aspect of future clinical magnetic particle imaging (MPI), this novel imaging technique can refer to expertise that is cumulated in the IEC standard for magnetic resonance imaging (MRI) safety. Both imaging techniques employ s

We present a concept for a combined selection and focus field generator for whole-body magnetic particle imaging (MPI). Predictions for field of view, gradient field strength, slew rate, and power consumption are calculated and discussed with the hel

Magnetic particle imaging (MPI) is an emerging tomographic method that enables sensitive and fast imaging. It does not require ionizing radiation and thus may be a safe alternative for tracking of devices in the catheterization laboratory. The 3-D re

A clinical MPI demonstrator system is being built [1] that will enable fast 3D imaging with 3D drive field excitation and rapid 3D focus fields. To date, all components have been realized only once, i.e., a 1D drive field coil (x direction), a 1D fas

Computer tomography(CT) scanners with an increasing number of detector rows offer the potential of shorter scanning times. Nevertheless, the reconstruction problem becomes more challenging, since cone beam artifacts are likely to enter. Here, we cons

The mathematical analysis of exact filtered back-projection algorithms is strictly related to Radon inversion. We show how filter-lines can be defined for the helical trajectory, which serve for the extraction of contributions of particular kinds of

In this paper, four approximate cone-beam CT reconstruction algorithms are compared: Advanced single slice rebinning (ASSR) as a representative of algorithms employing a two dimensional approximation, PI, PI-SLANT, and 3-PI which all use a proper thr

It seems that signal generating devices, especially those which were made of stainless steel, are not optimal for cardiovascular interventions, if these devices show ferromagnetic characteristics. CVI seem to be safe in MPI using non-signal generatin
