Photoacoustic-based thermal image formation and optimization using an evolutionary genetic algorithm

Abstract Introduction For improved efficiency and security in heat application during hyperthermia, it is important to monitor tissue temperature during treatments. Photoacoustic (PA) pressure wave amplitude has a temperature dependence given by the Gruenesein parameter. Consequently, changes in PA signal amplitude carry information about temperature variation in tissue. Therefore, PA has been proposed as an imaging technique to monitor temperature during hyperthermia. However, no studies have compared the performance of different algorithms to generate PA-based thermal images. Methods Here, four methods to estimate variations in PA signal amplitude for thermal image formation were investigated: peak-to-peak, integral of the modulus, autocorrelation of the maximum value, and energy of the signal. Changes in PA signal amplitude were evaluated using a 1-D window moving across the entire image. PA images were acquired for temperatures ranging from 36oC to 41oC using a phantom immersed in a temperature controlled thermal bath. Results The results demonstrated that imaging processing parameters and methods involved in tracking variations in PA signal amplitude drastically affected the sensitivity and accuracy of thermal images formation. The sensitivity fluctuated more than 20% across the different methods and parameters used. After optimizing the parameters to generate the thermal images using an evolutionary genetic algorithm (GA), the percentage of pixels within the acceptable error was improved, in average, by 7.5%. Conclusion Optimization of processing parameters using GA could increase the accuracy of measurement for this experimental setup and improve quality of PA-based thermal images.

Hypothermia Induced by Incorrect Monitoring of Core Temperature: A case report / 대한마취과학회지

A 55-year-old man was scheduled to undergo revisional total hip arthroplasty under general anesthesia. During the operation, a warm blanket and fluid warmer were applied, with his body temperature maintained at 35oC, as assessed with the use of a temporal-artery thermometer. In the course of the operation, severe bleeding developed, which required a massive transfusion of packed red blood cells and other blood components to correct the electrolyte and pH balances; the infusion of cardiovascular drugs was also preformed. However, the hemodynamic status of the patient deteriorated to severe hypotension, with atrial fibrillation, non-sustaining paroxysmal ventricular tachycardia and ventricular fibrillation. The patient was re-evaluated, and it was realized the temporal-artery thermometer had been incorrectly monitored, causing hemodynamic deterioration, which was assessed as hypothermia from a nasopharyngeal temperature of 29 degrees C. Active warming methods, including a condensed humidifier, and warming of the fluids and blood compounds with a rapid infusion system, were instigated, resulting in stabilization of the patient's hemodynamic status and the disappearance of his dysrhythmia.

Comparison of Temperatures at Various Sites during Open Heart Surgery Anesthesia / 대한마취과학회지

Because wide swings in temperature can occur during cardiac anesthesia all patients undergoing cardiac anesthesia should have their temperatures monitered. This is especially true in situations where deliberate hypothermia during cardiopulmonary surgery is an area of controversy. This study of 20 cases of open heart surgery was undertaken to compare the changes in tympanic membrane, nasopharyngeal, rectal and great toe temperatures and of to evaluate their correlation during the induction, cardiopulmonary bypass, rewarming and post-cardiopulmonary bypass periods. The temperature at each site was monitored every 10 minutes for 60 minutes of each period. The results were as follows, During the induction period, the temperature of the tympanic membrane, nasopharynx and rectum decreased significantly(p<0.05~p<0.01), but the temperatures of the great toe temperatures increased for 20 minutes and then slowly decreased during the next 30 to 60 minutes. During the cardiopulmonary bypass period, the sympanic membrane temperatures which were best correlated with the nasopharyngeal temperatures(p<0.05~p<0.01), decreased faster than the rectal, nasopharyngeal and great toe temperatures. During the rewarming period, the tympanic membrane temperatures increased most quickly and were significantly correlated with the nasopharyngeal temperatures(p<0.05) only at 0 and 10 minutes. During the post-cardiopulmonary bypass period, the tympanic membrane and nasopharyngeal temperatures decreased slowly and were significantly correlated with each other(p<0.01), but the rectal and the great toe temperatures increased slowly.
