Intraoperative margin assessment is needed to reduce the re-excision rate of breast-conserving surgery. One possibility is optical palpation, a tactile imaging technique that maps stress (force applied across the tissue surface) as an indicator of ti

Comparison between two handheld quantitative micro elastography methods (Conference Presentation)

Autor: Luke Frewer, Rowan W. Sanderson, Lixin Chin, Brendan F. Kennedy, Ben Dessauvagie, Ken Y. Foo, Bruce Latham, Devina D. Lakhiani, Renate R. Zilkens, Qi Fang, Christobel Saunders, James D. Anstie

Publikováno v: Optical Elastography and Tissue Biomechanics VII.

This presentation reports a comparison between two handheld quantitative micro elastography (QME) methods: PZT actuated compression QME and manual compression QME. PZT actuated compression QME utilizes a PZT actuator to provide a periodic compression

Compression optical coherence elastography (OCE) typically requires a mechanical actuator to impart a controlled uniform strain to the sample. However, for handheld scanning, this adds complexity to the design of the probe and

Diagnostic Accuracy of Quantitative Micro-Elastography for Margin Assessment in Breast-Conserving Surgery

Publikováno v: Cancer research. 80(8)

Inadequate margins in breast-conserving surgery (BCS) are associated with an increased likelihood of local recurrence of breast cancer. Currently, approximately 20% of BCS patients require repeat surgery due to inadequate margins at the initial opera

A method for handheld quantitative micro-elastography of excised human breast (Conference Presentation)

Autor: Benjamin F. Dessauvagie, Renate R. Zilkens, Bruce Latham, Brendan F. Kennedy, Christobel Saunders, James D. Anstie, Luke Frewer, Lixin Chin, Qi Fang, Brooke Krajancich, Philip Wijesinghe

Publikováno v: Optical Coherence Tomography and Coherence Domain Optical Methods in Biomedicine XXIII.

Approximately a quarter of patients undergoing breast conserving surgery will need further surgery as close or involved surgical margins suggest they may have residual tumour in the breast. Handheld imaging probes capable of scanning the surgical cav
