In this work, an effort has been made to determine the effect of different shape surgical burr on the thermogenesis during bone osteotomy. The abrasion during bone grinding leads to heat generation and subsequently rise in the temperature which may have adverse effects such as osteonecrosis, blood coagulation in the carotid artery, damage to sciatic nerves, and even loss of vision. So, mitigating the temperature rise during bone grinding is of paramount importance. Especially, in endoscopic endonasal approach (EEA) in which nasal passage is used for the inserting the grinding burr and reaching the target region. The miniature abrasion can significantly increase the temperature and hence leads to the thermal damage to nerves surrounding the temporal and frontal lobe. These parts of the brain controls movement, problem solving ability, behavior, personality mood, hearing, language, memory, speech, breathing, heart rate, consciousness etc. Furthermore, neurosurgeons rely on their personal surgical experience for estimating the temperature rise during grinding. However, this is much difficult for novice surgeons. Therefore, it becomes critically important to preserve the soft neural tissues and nerves amid bone grinding. To overcome these concerns, infrared thermography technique has been exploited to determine the possibility of thermogenesis during bone grinding by measuring the temperature rise and its distribution using infrared camera. All experiments have been carried at a constant set of process variables. The grinding zone is continuously flooded with the irrigating solution to remove the heat and bone debris away from the grinding site. It has been observed that convex tool shape generated lower maximum temperature i.e. 46.03 ℃ among all tools. The temperature produced by the convex tool is 12.06% lower than spherical tool, 33.39% lower than cylindrical tool, and 10.55% lower than tree-shape tool. The results showed that convex shape tool could prevent thermal necrosis in the bone as temperature caused (i.e. 46 ℃) was less than the threshold limit of osteonecrosis. Thermograms revealed that infrared thermography technique could be implemented for the in-vivo surgical operations for the measurement of temperature during bone grinding.

Przyczyną dużej śmiertelności pacjentek chorych na nowotwory piersi jest zbyt późna wykrywalność zmian nowotworowych. Konieczność wprowadzenia bezpiecznej i bezinwazyjnej metodyki stanowi obecnie wyzwanie badawcze. Jedną z metod, która może wspomóc diagnostykę nowotworów piersi, jest termografia w podczerwieni. Znalazła ona szerokie zastosowanie w wielu dziedzinach przemysłu, jak również z powodzeniem jest stosowana w medycynie. Kamery termowizyjne wraz ze specjalistycznym oprogramowaniem umożliwiają analizę obrazów termograficznych różnych schorzeń, w których zmiana zlokalizowana jest na powierzchni skóry lub pod jej powierzchnią, co stanowi zaletę, ale również i wadę tej techniki diagnostycznej. Niniejsza praca ma na celu przeprowadzenie badań, które pozwolą ocenić przydatność obrazowania termograficznego w diagnostyce, jak i efektach leczenia nowotworów piersi z wykorzystaniem radioterapii.

Currently, a large percentage of women’s deaths are breast cancers as opposed to other disease entities The reason for this is that the detectability of cancerous changes is too late Therefore, the current research challenge is the need to develop a new, safe and non-invasive methodology. Infrared thermography is one such method that can help diagnose the breast cancer It is a method that has successfully found application in many fields of science, including medicine. Thermal imaging cameras with specialized software allow for the analysis of thermographic images of diseases in which the lesion is located on the surface of the skin or just below the surface of the skin. Based on the temperature gradient, you can locate and assess the affected area. This work aims to conduct studies that will assess the usefulness of thermography imaging in diagnostics and to observe the effect of radiotherapy treatment of breast cancer.
