“…One key area where geophysical data analysis is making an impact in medical contexts is the analysis of biomedical signals. Techniques such as signal processing, time-series analysis, and spectral analysis, which are commonly used in geophysics to analyze seismic, electromagnetic, and other data, have been adapted to analyze medical signals like ECGs, EEGs, and even molecular data from gene expression studies [ 102 ]. These methods help identify patterns, anomalies, and trends within complex medical signals, aiding in the diagnosis of cardiac arrhythmias, neurological disorders, and genetic diseases [ 103 ].…”

To develop diagnostic imaging approaches, this paper emphasizes the transformational potential of merging geophysics with health sciences. Diagnostic imaging technology improvements have transformed the health sciences by enabling earlier and more precise disease identification, individualized therapy, and improved patient care. This review article examines the connection between geophysics and diagnostic imaging in the field of health sciences. Geophysics, which is typically used to explore Earth’s subsurface, has provided new uses of its methodology in the medical field, providing innovative solutions to pressing medical problems. The article examines the different geophysical techniques like electrical imaging, seismic imaging, and geophysics and their corresponding imaging techniques used in health sciences like tomography, magnetic resonance imaging, ultrasound imaging, etc. The examination includes the description, similarities, differences, and challenges associated with these techniques and how modified geophysical techniques can be used in imaging methods in health sciences. Examining the progression of each method from geophysics to medical imaging and its contributions to illness diagnosis, treatment planning, and monitoring are highlighted. Also, the utilization of geophysical data analysis techniques like signal processing and inversion techniques in image processing in health sciences has been briefly explained, along with different mathematical and computational tools in geophysics and how they can be implemented for image processing in health sciences. The key findings include the development of machine learning and artificial intelligence in geophysics-driven medical imaging, demonstrating the revolutionary effects of data-driven methods on precision, speed, and predictive modeling.

“…Integration of rock density results from satellite gravity and lithology distribution from satellite imagery results in more detailed lithological type interpretation with more specific physical conditions [20], [21]. Additional data from regional geological maps have important role in catalyzing data interpretation and geological conditions validation that have been previously mapped at the research location [22]- [24]. This study aims to optimize the geological mapping of Mount Semeru which is located in East Java Province, Indonesia, using a remote sensing method in the form of Global Gravity Model Plus (GGMPlus) satellite gravity and Landsat-8 level 2 satellite imagery.…”

Conventional geological mapping has high data accuracy but has ineffectiveness such as incomplete sample sweep coverage due to extreme topography, densely populated environmental conditions, and weather constraints in the field. Remote sensing is an effective alternative geological mapping solution through a combination of satellite gravity methods and satellite imagery interpretation. This study aims to apply remote sensing to obtain a more detailed distribution of Mount Semeru lithological types from regional geological maps. Integration of rock density results from satellite gravity and lithology distribution from satellite imagery results in a more detailed lithological types interpretation with more specific physical conditions of rock density. Relatively low rock density values (1.9 - 2.3 gr/cm3) distribution is at the top and foot of the mountain in the outermost areas of the study area indicating relatively thick pyroclastic material with relatively deep bedrock depth, and unconsolidated material. On the side of the body of the mountain slope, there is a relatively high rock density value (2.9 - 3.5 gr/cm3) with an indication of the formation of pyroclastic material which is relatively thinner with the presence of shallower bedrock and has consolidated material. Geological mapping optimization forms the basis for further research related to the planning and development of natural resources, as well as a more effective and efficient advanced geological mapping automation process.

“…The major aid of the work is to apply soil electrical resistivity to determine the regional groundwater potential and how it is vulnerable to surface contaminants. This is because, electrical resistivity has been identi ed as one of the most suitable geophysical tools for delineating groundwater potential [26,27,28,29,30].…”

Groundwater remains an essential natural resource that is found in every part of the Earth’s subsurface. However, the high level of borehole failures due to inadequate subsurface information about the regional hydrogeological nature has led to significant water scarcity in both rural and semi-urban regions. This study applies the vertical electrical sounding method to delineate regional aquifer potential alongside the vulnerability to the agrochemical activities in a rapidly emerging agricultural development at Kujama Farmland for groundwater development. Information obtained was used to construct the soil depth section and the groundwater potential as well as its protective capacity. The depth section shows that the study area is underlain by four distinctive geo-electric layers. The weathered/fractured unit was delineated as the water-bearing unit of the study area for groundwater development. The aquifer parameters such as resistivity and depth values vary between 21 Ωm – 328 Ωm and 19 m – 42 m, respectively. However, the observed thick aquifer with low resistivity values was considered as the region of the rich aquifer and it could supply sustainable water for drinking, domestic use and irrigation. Consequently, the siting of industrial/public/domestic boreholes should sunk to at least a depth of 30/20/10m respectively. On the other hand, the computed aquifer parameters show that the study is considered 75% highly protective, 22% moderately protective and 2% weakly protective from the possible surface contaminants emanating from the emerging agricultural activities at Kujama Multipurpose Farmland.
