“…The current project is focused on developing miniature, wireless, implantable temperature sensors to reconstruct the temperature field in real time—a capability which is yet unavailable for routine practice. This project combines two parallel efforts: (i) to develop the hardware necessary for implantable sensors [11,23], and (ii) to develop a method for temperature-field reconstruction in real time, which is the subject matter of the current study. This is a proof-of-concept level study, which uses prostate cryosurgery as a developmental model.…”

“…While hardware development is the subject matter of a parallel effort [11,23], its current state of development is overviewed here in brief, for the completeness of presentation only. Hardware development is aimed at an ultra-miniature, wireless, battery-less, implantable temperature-sensing device, having a diameter of 1.5 mm and a length of 3 mm to enable minimally invasive deployment through a hypodermic needle.…”

There is an undisputed need for temperature-field reconstruction during minimally invasive cryosurgery. The current line of research focuses on developing miniature, wireless, implantable, temperature sensors to enable temperature-field reconstruction in real time. This project combines two parallel efforts: (i) to develop the hardware necessary for implantable sensors, and (ii) to develop mathematical techniques for temperature-field reconstruction in real time—the subject matter of the current study. In particular, this study proposes an approach for temperature-field reconstruction combining data obtained from medical imaging, cryoprobe-embedded sensors, and miniature, wireless, implantable sensors, the development of which is currently underway. This study discusses possible strategies for laying out implantable sensors and approaches for data integration. In particular, prostate cryosurgery is presented as a developmental model and a two-dimensional proof-of-concept is discussed. It is demonstrated that the lethal temperature can be predicted to a significant degree of certainty with implantable sensors and the technique proposed in the current study, a capability that is yet unavailable.
