Magnetic Particle Imaging
Encyclopedia
Magnetic particle imaging (MPI) is a tomographic
imaging technique that measures
the magnetic field
s generated by magnetic particles in a tracer
. Researchers at Philips Research have used the technique to achieve resolutions finer than one millimeter. Magnetic Particle Imaging has potential applications in medicine
and material science. Recently, the first in-vivo results were published revealing structures of a beating mouse heart.
In comparison to the classic setup as a cave, the university of Lübeck in Germany is developing a single-sided MPI scanner. The single-sided MPI scanner could be used like a subsonic device.
Tomography
Tomography refers to imaging by sections or sectioning, through the use of any kind of penetrating wave. A device used in tomography is called a tomograph, while the image produced is a tomogram. The method is used in radiology, archaeology, biology, geophysics, oceanography, materials science,...

Measurement
Measurement is the process or the result of determining the ratio of a physical quantity, such as a length, time, temperature etc., to a unit of measurement, such as the metre, second or degree Celsius...
the magnetic field
Magnetic field
A magnetic field is a mathematical description of the magnetic influence of electric currents and magnetic materials. The magnetic field at any given point is specified by both a direction and a magnitude ; as such it is a vector field.Technically, a magnetic field is a pseudo vector;...
