Computational pathology applies image-analysis methods to digitized tissue slides.

Whole-slide images are large, so models often process patches and combine patch-level evidence for slide-level tasks.
The FDA De Novo review for Paige Prostate describes a computer-assisted pathology device that identifies suspicious areas on digitized prostate biopsy slides for pathologist review. CLAM is a research approach using attention-based multiple-instance learning for whole-slide classification with slide-level labels. Ki-67 is a cell-proliferation marker discussed in oncology. These tools and markers address specific tasks; their research or regulatory status does not generalize to every tissue, cancer or clinical decision.
A whole-slide image can be divided into tiles for model processing.
Multiple-instance learning can learn from slide-level labels when every patch is not individually annotated.
The FDA-reviewed Paige Prostate device assists pathologists with a specific prostate-biopsy review task.
Ki-67 is a protein marker used in assessing cell proliferation; an AI count is a measurement aid, not a standalone cancer diagnosis.
Report the tissue type, scanner, population, reference standard and intended use when evaluating pathology AI. Keep pathologist oversight and assess performance across sites and specimen types. A clearance or benchmark for one device does not establish general clinical utility across pathology.

Computational pathology applies image-analysis methods to digitized tissue slides. Whole-slide images are large, so models often process patches and combine patch-level evidence for slide-level tasks.
Slide dipindai menjadi gambar gigapiksel yang sangat besar, seringkali miliaran piksel, yang kemudian dianalisis oleh AI.
Gambar keseluruhan slide terlalu besar untuk masukan model, sehingga gambar tersebut dipecah menjadi ribuan ubin dan hasilnya digabungkan ulang.
FDA’s DEN200080 record is a De Novo classification for a specific software device and intended use; the decision does not generalize to all pathology AI.
Ki-67 adalah penanda proliferasi sel, dan penghitungan sel positif menunjukkan seberapa agresif pertumbuhan tumor.
The cited FDA review describes a device intended to assist pathologists; its output is not a standalone diagnosis or treatment decision.
