Abstract: An method of malaria detection includes providing an interdigitated sensor having a first electrode with a plurality of fingers and a second electrode with a plurality of fingers, interspersed and spaced apart from the fingers of the first electrode. A quantity of blood to be tested is received on the sensor. The blood is to be dried and is measured for at least one measurable characteristic, including a resistance of the blood. The presence of malaria infected blood is determined based on a comparison between the measurable characteristics and a predetermined threshold related to the measurable characteristics.

Abstract: The present invention provides a method of handling rapid phase aliasing in magnetic resonance images arising from local magnetic susceptibility differences. The methods of the present invention can be used to estimate the field effects within an object arising from the interfaces of regions having differences in magnetic susceptibilities, and to subtract out the resulting phase from the original or source phase data prior to any further phase processing. The methods of the present invention also include a process of accurately determining the susceptibility values of multiple voxel regions based on the geometry of such regions.

Abstract: A method comprises digitally representing a volume of space as a plurality of voxels and assigning real and imaginary values derived from magnetic resonance imaging data of the space to each of the voxels. Furthermore, the method comprises a steps of calculating a first complex summation of the real and imaginary values of a first set of the voxels, and calculating a second complex summation of the real and imaginary values of a second set of the voxels. Each set of voxels represents a different region of the volume of space. The regions are concentric. The method also comprises steps of using the first and second summations, along with another value quantitatively calculated from the magnetic resonance imaging data, to calculate a value that is dependent upon the approximate magnetic moment of an object within the volume of space, and digitally representing and storing said value.
