Abstract: A system for surgical planning and assessment of spinal deformity correction is provided that has a spinal imaging system and a control unit. The spinal imaging system is configured to collect at least one digitized position of one or more vertebral bodies of a subject. The control unit is configured to receive the at least one digitized position, and calculate, based on the at least one digitized position, an optimized posture for the subject. The control unit is configured to receive one or more simulated spinal correction inputs, and based on the inputs and optimized posture, predict an optimal simulated postoperative surgical correction.

Abstract: Embodiments of the present invention are directed to methods, systems, and software for assessing contaminant quantities in a fluid. Fluid enters a reaction chamber. A controller then signals two different sheets with different reagents to move into the reaction chamber. One sheet contains reagents to form a contaminant byproduct or gas, while the other sheet is saturated with reagent that will have a photometric effect upon reacting with the contaminant byproduct or gas. After the photometric effect has occurred, the controller moves the reacted portion of the other reagent sheet into alignment with a photometric sensor. This photometric effect is calculated to contaminant concentration. The concentration is recorded and the data is transmitted to memory. The fluid sample in the chamber is drained and the remaining solid waste is collected onto the first reagent sheet. Both sheets are individually collected into separate controllable collectors.
