Abstract
One method for estimating the extracorporeal blood volume in a portion of a physical sample includes: extracting a feature from a portion of an image of the sample; tagging the portion of the image of the sample with a blood volume indicator according to the extracted feature; and estimating the extracorporeal blood volume in at least the portion of the physical sample, associated with the portion of the image of the sample, according to the blood volume indicator.

29. A method for estimating extracorporeal fluids from a patient, the method comprising:
-
extracting a feature from an image of a first physical sample, wherein the first physical sample comprises at least one extracorporeal fluid; determining a fluid volume indicator based on the extracted feature; estimating a first extracorporeal fluid volume in at least a portion of the first physical sample based on the fluid volume indicator; and estimating a second extracorporeal fluid volume in a second physical sample based at least in part on a weight or mass of the second physical sample. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36, 37, 38, 39)

40. A system for estimating extracorporeal fluids from a patient, the system comprising:
-
an optical sensor configured to capture an image of at least a portion of a first physical sample; a scale configured to determine a weight or mass of a second physical sample; and a processor configured to; extract a feature from the image of at least a portion of the first physical sample; estimate a first extracorporeal fluid volume in at least a portion of the first physical sample based on a fluid volume indicator correlated to the extracted feature; and estimate a second extracorporeal fluid volume in the second physical sample based at least in part on the weight or mass of the second physical sample. - View Dependent Claims (41, 42, 43, 44, 45, 46, 47, 48, 49, 50)
