Abstract: The present invention provides a simple, inexpensive apparatus for and method of capturing biological or other material from sample suspensions on a collection surface and for depositing captured material on a receiving surface, such as a microscope slide, for observation and analysis. Accordingly, cytological material may be deposited in near mono-layers for the detection of disease. In one embodiment of the present invention, density gradients of material are captured and deposited, thus providing a desired range of concentrations for examination. In another embodiment multiple depositions or multiple slides may be made from the same sample suspension. The method and apparatus to exploit this new method are both presented for various applications. The dimensions of material captured and deposited may be controlled and used in conjunction with microscope slides that confine material to specific regions of interest.

Abstract: Computer programs, systems and the like related to processing, segmenting and feature normalizing digital images. The images are of cells and the methods are useful for the detection of malignancy-associated changes (MAC) in cells, which can be used for the detection of cancer. The programs and methods detect cancer in one tissue by detecting MAC in another tissue, such as associated tissues or non-associated tissues. Examples of associated tissues include nipple aspirates or ductal washings to detect breast cancer, and sputum or bronchial lavage to detect lung cancer. Examples of non-associated tissues include buccal mucosa to detect lung or breast cancer.
