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)

EXPERIMENTAL

In 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).

Diagnostic Test: Diffuse reflectance spectroscopy and Photoacoustic imaging,

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.
