Scan data retrieval with depth sensor data

Abstract

In scan data retrieval, a mesh is fit () to surface data of a current patient, such as data from an optical or depth sensor (). Meshes are also fit () to medical scan data, such as fitting () to skin surface segments of computed tomography data. The meshes or parameters derived from the meshes may be more efficiently compared () to identify () a previous patient with similar body shape and/or size. The scan configuration () for that patient, or that patient as altered to account for differences from the current patient, is used. In some embodiments, the parameter vector used for searching () includes principle component analysis coefficients. In further embodiments, the principle component analysis coefficients may be projected to a more discriminative space using metric learning.
