This dataset is composed of four files, each detailing measurements taken with a range of 3D scanning applications of ten residual limbs. These measurements include the perimeter, area, and volume of limbs in addition to their RMSE (Root Mean Squared Error) compared to a baseline criterion scan. All of these measurements were performed in Artec Studio 12, by splitting residuum scans into ten evenly-space sections along the relevant portion of the limb. Two types of measurement are collected; Naive, in which the scans are scaled solely using the reference object captured in the scan data, and Optimal, in which the scans are scaled relative to the captured criterion scans. The latter considers a best-case scenario that isolates the efficacy of the geometry captured, minimising the impact of human-error when scaling the scan data.

Compiled Environment Data - Scan data from 4 different applications and the criterion gathered from a transtibial plaster cast model, containing measurements of section data pertaining to perimeter, cross-sectional area and volume, across several different environments with disparate lighting conditions. These are split into Naive (N) and Optimal (O) datasets. Each application is listed under 'Scan Name', with their repeated scans labeled 1-3. 'PolycamPG' and 'LumaPG' relate to the web versions of each application discussed.

Compiled Participant Data - Scan data across 10 different residual limbs for each application, against the criterion scanner.  This file contains all section data pertaining to the perimeter, cross-sectional area, and volume for each participant in the study. These are split into Naive (N) and Optimal (O) datasets. Each application is listed under 'Scan Name', with their repeated scans labeled 1-3. 'PolycamPG' and 'LumaPG' relate to the web versions of each application discussed.

Reliability and Validity Data- A compilation of the Participant Validity and Reliability Data included in the previous dataset, condensed into a dedicated file for the readers convenience.

RMSE Data- A collection of all RMSE (Root Mean Squared Error) data collected from participant scans. All scans were compared against a baseline Artec scan, and relevant values were collected and stored in this data sheet. Comparisons were made between the tops and bottoms (anterior and posterior) sides of the residual limbs.
