Abstract

fetched live from OpenAlex

Photonic imaging is based on the light–tissue interactions when the bronchial surface is illuminated by light. This chapter focuses on the use of photonic imaging for diagnosis of central and peripheral lung cancers. Endoscopic imaging, whether white light bronchoscopy (WLB), autofluorescence bronchoscopy, photodiagnosis using photosensitizers, narrow-band imaging (NBI), optical coherence tomography or Raman spectroscopy, is based on the light–tissue interaction properties. The sensitivity of autofluorescence bronchoscopic device (AFB) and NBI is higher than WLB for detection of preinvasive and early invasive lesions but the specificity is lower. Laser Raman spectroscopy (LRS) in combination with AFB +WLB demonstrated increased specificity in identifying lung cancer. A pilot study suggested LRS may reduce the number of biopsies. Optical imaging modalities including AFB device and NBI demonstrate superior sensitivity in detecting early lung cancer in the central airways.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
