Advantages and Disadvantages of Parameter Search Algorithms for Permittivity Estimation for Microwave Breast Imaging
O'Loughlin, Declan (IEEE, 2019)Multiple clinical investigations of radar-based breast imaging devices have been demonstrated in recent years, including two competing commercial systems which are currently being tested in clinics. Ongoing trials include ... -
Assessing Patient-Specific Microwave Breast Imaging in Clinical Case Studies
O'Loughlin, Declan (2021)Microwave breast imaging has seen increasing use in clinical investigations in the past decade with over eight systems having being trialled with patients. The majority of systems use radar-based algorithms to reconstruct ... -
Design limitations of using magnetic inductive coupling to verify nasogastric tube placement
O'Loughlin, Declan (2023)Nasogastric tube insertion is a standard procedure but with potentially fatal consequences if misplaced. Many bedside methods have been proposed for identifying misplace- ment including magnetic inductive coupling. This ... -
Design of a Tetrapolar Probe for Electrical Characterization of the Left Atrial Appendage from 0.1 Hz to 100 kHz
O'Loughlin, Declan (2022)Recently, non-thermal pulsed-field-ablation using electroporation has generated a lot of interest as a potential treatment for Atrial Fibrillation. The electrical properties, and specially the conductivity of cardiac ... -
Developments in Open-Source Tools for Microwave Breast Imaging
O'Loughlin, Declan (2024)Open-source models, datasets and toolboxes are becoming increasingly common in the microwave breast imaging literature, including numericial breast models, simulated and experimental datasets and imaging and analysis ... -
Dielectric Properties of Ovine Heart at Microwave Frequencies
O'Loughlin, Declan (2021)Accurate knowledge of the dielectric properties of biological tissues is important in dosimetry studies and for medical diagnostic, monitoring and therapeutic technologies. In particular, the dielectric properties of the ... -
Effects of Interpatient Variance on Microwave Breast Images: Experimental Evaluation
O'Loughlin, Declan (IEEE, 2018)Microwave breast imaging has seen significant developments in recent years, including new clinical trials and formation of a number of spin-out companies. Although many algorithms for microwave breast imaging have been ... -
Estimating Average Dielectric Properties for Microwave Breast Imaging Using Focal Quality Metrics
O'Loughlin, Declan (2016)Confocal Microwave Imaging algorithms synthetically focus backscattered radar signals to create an image of the breast. Spatial focusing is achieved by delaying the received signals by the round-trip propagation delay to ... -
Evaluation of Experimental Microwave Radar-Based Images: Evaluation Criteria
O'Loughlin, Declan (IEEE, 2018)Microwave imaging has seen an increasing amount of clinical trials in the last two years, including ongoing and planned commercial development. The rapidly increasing number of studies with patient imaging is encouraging ... -
Identifying Microwave Antenna Design Limitations for Radar-based Breast Imaging
O'Loughlin, Declan (2022)The electrical properties of many biological tissues are freely available from the INRC and the IT’IS databases. However, particularly in lower frequency ranges, few studies have investigated the optimal measurement protocol ... -
Pathway to Demonstrating Clinical Efficacy of MIcrowave Breast Imaging: Qualitative and Quantitative Performance Assessment
O'Loughlin, Declan (2022)n the last five years alone, there has been an increasing number of operational microwave breast imaging systems used in clinical trials, with increasingly large and diverse patient populations. However, despite this ... -
Probe Contact Force Monitoring during Conductivity Measurements of the Left Atrial Appendage to Support the Design of Novel Diagnostic and Therapeutic Procedures
O'Loughlin, Declan (2022)The electrical properties of many biological tissues are freely available from the INRC and the IT’IS databases. However, particularly in lower frequency ranges, few studies have investigated the optimal measurement protocol ...
