Claim 11:
12. A method comprising:
providing a sensor head for a tissue oximetry device comprising an arrangement of source structures and detector structures comprising:
a first source structure and a second source structure;
a plurality of detector structures arranged asymmetrically in the arrangement, asymmetric about a point on a line passing through the first and second source structures;
a first detector structure of the arrangement, wherein a first distance is from the first detector structure to the first source structure, a second distance is from the first detector structure to the second source structure, and the first distance is greater than the second distance;
a second detector structure of the arrangement, wherein a third distance is from the second detector structure to the first source structure, a fourth distance is from the second detector structure to the second source structure, and the fourth distance is greater than the third distance;
a third detector structure of the arrangement, wherein a fifth distance is from the third detector structure to the first source structure, a sixth distance is from the third detector structure to the second source structure, the fifth distance is different from the first distance and the second distance, and the sixth distance is different from the first distance and the second distance; and
a fourth detector structure of the arrangement, wherein a seventh distance is from the fourth detector structure to the first source structure, an eighth distance is from the fourth detector structure to the second source structure, the seventh distance is different from the first, second, fifth, and sixth distances, and the eighth distance is different from the first, second, fifth, and sixth distances; and
using information collected from the plurality of detector structures arranged asymmetrically to determine a correction due to a variation between the first and second source structures and an oxygen saturation value and not using the third and fourth detector structures to determine the correlation.
