Study of female pelvic floor muscle in overactive bladder based on MRI 3D reconstruction

BMC Urology, 2022
Background This study examined the three-dimensional (3D) morphological changes of the urination and urinary continence anatomical structures in overactive bladder (OAB) patients, to offer a morphological data for OAB diagnosis and treatment.

Inherent Reflectance Variability of Vegetation

Agriculture, 2019
With the inception of small unmanned aircraft systems (sUAS), remotely sensed images have been captured much closer to the ground, which has meant better resolution and smaller ground sample distances (GSDs).

Biophysical Measurements of Cells, Microtubules, and DNA with an Atomic Force Microscope [PDF]

, 2014
Atomic force microscopes (AFMs) are ubiquitous in research laboratories and have recently been priced for use in teaching laboratories. Here we review several AFM platforms (Dimension 3000 by Digital Instruments, EasyScan2 by Nanosurf, ezAFM by ...

Automatic Magnetic Resonance Image Prostate Segmentation Based on Adaptive Feature Learning Probability Boosting Tree Initialization and CNN-ASM Refinement

IEEE Access, 2018
This paper proposes a method based on the active shape model (ASM) to segment the prostate in magnetic resonance (MR) images. Due to the great variability in appearance among different boundaries of the prostate and among subjects, the traditional ASM is

Ghost imaging with engineered quantum states by Hong-Ou-Mandel interference [PDF]

, 2019
Traditional ghost imaging experiments exploit position correlations between correlated states of light. These correlations occur directly in spontaneous parametric down-conversion (SPDC), and in such a scenario, the two-photon state used for ghost ...

An Automated and Accurate Spine Curve Analysis System

IEEE Access, 2019
We present a new Adaptive Error Correction Net (AEC-Net) to formulate the estimation of Cobb anges from spinal X-rays as a high-precision regression task. Our AEC-Net introduces two novel innovations.

An investigation of the relationship between thermal imaging and digital thermometer [PDF]

, 2015
BACKGROUND: A number of research papers and theoretical clinical models summarising how temperature of the skin over the knee may be altered according to different pathological processes have been published. Thermal imaging (TI) is generally regarded as

Digital spiral imaging

Optics Express, 2005
A major application of optics is imaging all types of structural, physical, chemical and biological features of matter. Techniques based on most known properties of light have been developed over the years to remotely acquire information about such features.
