A Comparison of Property Estimators in Stereology and Digital Geometry
We consider selected geometric properties of 2D or 3D sets, given in form of binary digital pictures, and discuss their estimation. The properties examined are perimeter and area in 2D, and surface area and volume in 3D. We evaluate common estimators in stereology and digital geometry according to their multiprobe or multigrid convergence properties, and precision and efficiency of estimations....

1.1 組織標本を使用する定量解析が抱える諸問題 組織標本の解析は定性的な所見から始まる.顕微鏡を用いた丁寧な観察によって初めて得られる検体の 大きさや分布,形態などについての詳細な情報は,全ての研究の基礎となるべき重要なものである.しか しながら,定性的なデータだけでは,統計学的な検討が難しく,結果が主観的なものになりやすい.この ため,生理的組織と病的組織の比較など,さらなる研究を行う際には,定量的なデータが必要になる.定 量解析の基本的な命題は,いかにして検体の正確な数を客観的に求めることができるか,ということであ る.組織標本に基づく定量解析は単純に思われるが,正確なデータを得ることは実は容易ではない. 最大の問題は,サンプリングバイアスである(図1).これは,標本抽出の際に母集団を代表していない 検体が選ばれるために生じる偏りのことであり,2次元的な切片を使って定量解析を行...
متن کاملApplicability of digital analysis and imaging technology in neuropathology assessment.
Alzheimer's disease (AD) is a progressive neurological disorder that affects more than 30 million people worldwide. While various dementia-related losses in cognitive functioning are its hallmark clinical symptoms, ultimate diagnosis is based on manual neuropathological assessments using various schemas, including Braak staging, CERAD (Consortium to Establish a Registry for Alzheimer's Disease)...

متن کاملSampling for stereology in lungs
The present article reviews the relevant stereological estimators for obtaining reliable quantitative structural data from the lungs. Stereological sampling achieves reliable, quantitative information either about the whole lung or complete lobes, whilst minimising the workload. Studies have used systematic random sampling, which has fixed and constant sampling probabilities on all blocks, sect...
