Special Issue Information

Dear Colleagues,

During the past decade, there has been an explosion in the development of novel optics, ultrasound and imaging techniques in biomedical research and clinical applications. Significant progresses have been observed in to provide new and improved biological information contributing to better diagnosis and in-depth understanding of the biological processes. Moreover, recent advances in machine learning or in particular deep learning has significantly advanced the diagnostic capability and have enabled novel diagnostic and treatment approaches for different types of diseases.

This special issue aims to report the latest advances in biomedical optics, ultrasound and other imaging techniques along with the state-of-the-art machine learning algorithms for analyzing them for early prediction, diagnosis or treatment planning for various diseases. 

This special issue will publish high-quality, original research and review papers, in the following fields: 

  • Explainable AI for medical imaging
  • Imbalance data problem in medical image analysis
  • Optical coherence tomography, color fundus photography, X-rays, CT, ultrasound, whole slide and other medical image modalities
  • Registration and segmentation of medical images
  • Disease prediction, diagnosis and prognosis using medical images
  • Medical image enhancement and noise reduction
  • Machine learning and deep learning
  • Medical image processing and reconstruction
  • Optical image guided surgery
  • Multimodal imaging or sensor integration

Stargardt disease is the most common form of juvenile-onset macular dystrophy. Spectral-domain optical coherence tomography (SD-OCT) imaging provides an opportunity to directly measure changes to retinal layers due to Stargardt atrophy. Generally, atrophy segmentation and prediction can be conducted using mean intensity feature maps generated from the relevant retinal layers. In this paper, we report an approach using advanced OCT-derived features to augment and enhance data beyond the commonly used mean intensity features for enhanced prediction of Stargardt atrophy with an ensemble deep learning neural network. With all the relevant retinal layers, this neural network architecture achieves a median Dice coefficient of 0.830 for six-month predictions and 0.828 for twelve-month predictions, showing a significant improvement over a neural network using only mean intensity, which achieved Dice coefficients of 0.744 and 0.762 for six-month and twelve-month predictions, respectively. When using feature maps generated from different layers of the retina, significant differences in performance were observed. This study shows promising results for using multiple OCT-derived features beyond intensity for assessing the prognosis of Stargardt disease and quantifying the rate of progression. Full article

For the quick identification of diverse types of cancer/malignant cells in the human body, a new hollow-core optical waveguide based on Photonic Crystal Fiber (PCF) is proposed and numerically studied. The refractive index (RI) differs between normal and cancerous cells, and it is through this distinction that the other crucial optical parameters are assessed. The proposed cancer cell biosensor’s guiding characteristics are examined in the COMSOL Multiphysics v5.5 environment. The Finite Element Method (FEM) framework is used to quantify the display of the suggested fiber biosensor. Extremely fine mesh elements are additionally added to guarantee the highest simulation accuracy. The simulation results on the suggested sensor model achieve a very high relative sensitivity of 99.9277%, 99.9243%, 99.9302%, 99.9314%, 99.9257% and 99.9169%, a low effective material loss of 8.55×10−5 cm−1, 8.96×10−5 cm−1, 8.24×10−5 cm−1, 8.09×10−5 cm−1, 8.79×10−5 cm−1, and 9.88×10−5 cm−1 for adrenal gland cancer, blood cancer, breast cancer type-1, breast cancer type-2, cervical cancer, and skin cancer, respectively, at a 3.0 THz frequency regime. A very low confinement loss of 6.1×10−10 dB/cm is also indicated by the simulation findings for all of the cancer cases that were mentioned. The straightforward PCF structure of the proposed biosensor offers a high likelihood of implementation when used in conjunction with these conventional performance indexes. So, it appears that this biosensor will create new opportunities for the identification and diagnosis of various cancer cells. Full article
