Equivalent accuracy of image‐based and imageless robotic platforms in achieving planned femoral rotation in primary total knee arthroplasty: A CT‐based study

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Robotic‐assisted total knee arthroplasty (TKA) is increasingly adopted worldwide, yet comparative data on the rotational accuracy of image‐based and imageless platforms remain limited. The aim of this study was to compare the accuracy of image‐based and imageless robotic platforms in achieving planned femoral rotation in primary TKA ...

Association of Neighborhood Deprivation With Breslow Thickness in Head and Neck Cutaneous Melanoma

The Laryngoscope, EarlyView.
Neighborhood socioeconomic deprivation, measured by the Area Deprivation Index (ADI), was independently associated with greater Breslow thickness in patients with primary head and neck cutaneous melanoma treated at a single tertiary care center. Patients residing in the most deprived neighborhoods had, on average, 1.40 mm greater tumor thickness ...

Jointly Exploiting Sentinel-1 and Sentinel-2 for Urban Mapping

IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018
This work introduces two feature fusion techniques that exploit previously developed algorithms for urban extent extraction from multispectral and SAR spaceborne data, adapting them to the joint use of Sentinel-l (S1) and Sentinel-2 (S2) data sets. The approaches aim at exploiting the finer spatial and spectral resolution of multispectral S2 data as ...

Sentinel-1 & Sentinel-2 Data for Soil Tillage Change Detection

IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018
In this paper, an algorithm using Sentinel-1 (S-1) and Sentinel-2 (S-2) data to identify changes of tillage over agricultural fields at approximately similar to 100m resolution is presented. The methodology implements a multiscale temporal change detection on S-1 VH backscatter in order to single out VH changes due to agricultural practices only.
