Abstract
A method of detecting and treating tumors within a subject is disclosed together with a process for the non-invasive measurement of tissue temperature within a subject.
Claims3
A method of detecting and treating tumors within a subject comprising:
- administering a dosage of magnetic material containing substance to a subject, said magnetic material containing substance adapted for preferential attachment to tumor cells;
- detecting location within said subject of said magnetic material containing substance attached to tumor cells by use of a sensor array including superconducting quantum interference devices;
- and,
- manipulating by a low frequency field said magnetic material within said subject such that said magnetic material containing substance undergoes heating whereby tumor cells having said attached magnetic material are heated sufficiently to cause selective necrosis of at least a portion of said tumor cells, wherein said manipulating magnetic material within said subject includes applying a rotational field to selected portions of said subject whereby said magnetic material containing substance undergoes a rotation to yield viscous heating.

A process for the non-invasive measurement of tissue temperature within a subject comprising:
- administering a dosage of magnetic material containing substance to a subject, said magnetic material containing substance adapted for preferential attachment to selected tissue;
- measuring Barkhausen noise associated with magnetic domains delivered to such selected tissue;
- and,
- correlating a tissue temperature with said measured Barkhausen noise.
