Prediction of temperature distribution for superficial hyperthermia treatment: Accuracy of temperature dependent blood perfusion model

Abstract

During superficial hyperthermia treatment (SHT), temperature in region of interest is increased to 40-43 • C, in order to enhance the therapeutic effect of standard radiotherapy and chemotherapy treatments. Temperature increase during SHT is usually monitored using invasive thermometry which is burden for the patient. We strongly believe that superficial hyperthermia treatment planning has a potential replacing invasive thermometry system in clinical practice. In this study we have investigated accuracy of temperature prediction in SHT using temperature dependent blood perfusion model for muscle and fat. For 40 patients treated with recurrent breast cancer recurrences at the chest wall we compared 294 invasively measured and predicted temperature profiles. We found difference of 0.88±1.69 • C (mean±standard deviation) with root mean square difference of 1.9 • C.

A Validated Methodological Approach to Prove the Safety of Clinical Electromagnetic Induction Systems in Magnetic Hyperthermia

“…Rather than handling blood perfusion as a static parameter, a more realistic approach was adopted. This approach was based on the findings of Drizdal et al [27], which highlighted the temperature-dependent behavior of blood perfusion during superficial hyperthermia. The results of Drizdal et al suggest that blood perfusion exhibits dynamic variations with changes in temperature.…”

Dipole antenna design as hyperthermia applicator using CST microwave studio

“…The phrase 'hyperthermia' refers to several heat treatment procedures used in addition to other therapies. [1][2][3][4] These techniques provide high temperatures, [5][6][7][8] potentially causes direct damage to cancer cells compared to chemotherapy treatment with minimal or no harm to normal tissues and therefore this technique applied as an anti-drug for cancer treatment. The temperature of the hyperthermia treatment varies from 40 o C to 48 o C, and the heat temperature retained at the treatment area for one hour or more.…”

Design of a contactless body temperature measurement system using Arduino

“…The status of health below this limit is stated as hypothermia and the status above is refered as fever and hyperthermia conditions. The hyperthermia also refered as tumour conditional stage that ranges more than 38.5 0 C [5][6][7]. The individual body temperature measurement is dependent of different aspects i.e.…”
