Tissue-mimicking phantom materials with tunable optical properties suitable for assessment of diffuse reflectance spectroscopy during electrosurgery

Emerging intraoperative tumor margin assessment techniques require the development of more complex and reliable organ phantoms to assess the performance of the technique before its translation into the clinic. In this work, electrically conductive tissue-mimicking materials (TMMs) based on fat, water and agar/gelatin were produced with...

Electrosurgical knife equipped with diffused reflectance spectroscopy sensing for tumor margin detection during breast conserving surgery: A phantom study

Distinguishing the diseased breast tissue from the healthy tissue is a sorely challenging task for the surgeons during breast conserving surgery (BCS) as both tissues own relatively similar visual and haptic characteristics. It has been shown that diffused reflectance spectroscopy (DRS) has the potential to be used as a real-time tumor margin...

Developing a Breast Phantom to Test and Validate the Smart Electrosurgical Knife

Previous studies show that the smart electrosurgical knife, which adds diffuse reflectance spectroscopy to the traditional electrosurgical knife, is a promising technique for breast-conserving surgery, namely it enables real-time tissue characterization while cutting. More specifically, based on the fat/water-ratio, it enables intraoperative...

Preventing falls among the community-dwelling elderly: Analyzing the impact of fall prevention programs and evaluating the applicability of a Health Impact Bond

Fall prevention programs hold great promise to improve quality of life among older adults and to decrease healthcare expenditures. However, there are substantial barriers for entrepreneurs working in the elderly care to set up fall prevention programs, due to the size of the investments required, the uncertainty of the parties about the...
