1. A multi-sensor apparatus measuring physiological parameters from a tissue site of a patient, the apparatus comprising:
a plurality of non-invasive sensors configured to obtain physiological data from an overlapping area of the tissue site of a patient; and
a sensor head comprising:
a frame comprising a plurality of angled cavities, each of the plurality of angled cavities fixedly orienting one of the plurality of non-invasive sensors relative to the frame, each of the plurality of non-invasive sensors configured to emit light along a light path towards the overlapping area of the tissue site, wherein at least one of the plurality of cavities is non-parallel to another one of the plurality of cavities such that, when the multi-sensor apparatus is in use, the light paths of each of the plurality of non-invasive sensors converge on the overlapping area of the tissue site; and
a tissue interaction section configured to be proximate the tissue site of the patient, wherein each of the plurality of non-invasive sensors are configured to obtain the physiological data associated with the patient at the tissue site.
