Outcome Measures
Primary Outcomes (1)
Number of study subjects with correctly classified breast tissue type with PAI/DRS
To evaluate if optical techniques (DRS/PAI) can differentiate between three breast tissue types, namely healthy, benign and malignant tissue. Differences in the optical tissue-properties will be compared to histopathological evaluation.
30 days
Secondary Outcomes (2)
Optical signal in relation to photoacoustic imaging depth
2 days
To assess oxygenation levels across three breast tissue types using PAI
Immediately after photoacoustic imaging acquisition
Study Arms (1)
Diagnostic (Diffuse reflectance spectroscopy or Photoacoustic imaging)
EXPERIMENTALIn part I, 30 breast specimens will be examined by DRS (ex-vivo). In part II, 30 breast specimens will be examined by both DRS and PAI (ex-vivo). In part III, 30 individuals will be examined by PAI (in-vivo).
Interventions
The photoacoustic imaging/diffuse reflectance spectroscopy techniques used in this study have a broader wavelength spectrum. The photoacoustic set-up can generate an optical and an ultrasound image simultaneously.
