This study was designed to re-examine the same soft palates studied qualitatively in a previous investigation (Kuehn and Kahane, 1990), using a true-color image analysis system. The quantified measures of the areas of specific tissue types are reported. The results indicate that: (a) tendinous tissue is prominent anteriorly and comprises about 10% of total tissue in that region, (b) the relative proportion of glandular and connective tissue is fairly uniform across the length of the soft palate, averaging 22% and 36% respectively, (c) muscle tissue shows a pattern of increasing then decreasing amount from anterior to posterior with a maximum proportion of 23% in the midportion of the soft palate, (d) adipose tissue comprises 22% of total tissue area in the anterior segment and 17% of total tissue area in the posterior segment of the soft palate, (e) other tissue, primarily epithelium and vascular tissue, was found to be fairly constant anteriorly and increased in relative proportion to almost 30% of the total tissue area at the uvular base. The functional implications of these findings are discussed.

The magnitude of error in estimating axial resistances was assessed using the diameters of xylem vessels of different shapes, measured using four different methods. Statistical analyses showed that the diameter measurements obtained using the different methods, were significantly different at the 0.001 level of significance. Using the Tukey test, the diameters obtained using the 'four axes' method were not significantly different from the actual diameters obtained using the Chromatic Color Image Analysis System. By using the 'Lewis' method for measuring the xylem diameter, axial resistance was overestimated by a factor of 1.6. Thus, the error caused by the method of measurement may partly explain why, in some studies, the estimated axial resistances have always been different from the measured resistances. The 'four axes' method is the simplest and most reliable and gives results very close to the actual diameters, compared with the other three methods.

Morphologic Criterion

Increased nuclear size, resulting in an increase in the relative proportion of nuclear to cytoplasmic sizes, is an important morphologic criterion for the evaluation of neoplastic and pre-neoplastic cells. This paper describes investigations into the suitability of automated image analysis for quantitating changes in nuclear and cytoplasmic cross-sectional areas in exfoliated cells from tracheas treated with carcinogen.Neoplastic and pre-neoplastic lesions were induced in the tracheas of Syrian hamsters with the carcinogen N-methyl-N-nitrosourea. Cytology samples were collected intra-tracheally with a specially designed catheter (1) and stained by a modified Papanicolaou technique. Three cytology specimens were selected from animals with normal tracheas, 3 from animals with dysplastic changes, and 3 from animals with epidermoid carcinoma. One hundred randomly selected cells on each slide were analyzed with a Bausch and Lomb Pattern Analysis System automated image analyzer.

Dose Imaging

We have assembled an image processing system for use with our high resolution STEM for the particular purpose of working with low dose images of biological specimens. The system is quite flexible, however, and can be used for a wide variety of images.The original images are stored on magnetic tape at the microscope using the digitized signals from the detectors. For low dose imaging, these are “first scan” exposures using an automatic montage system. One Nova minicomputer and one tape drive are dedicated to this task.The principal component of the image analysis system is a Lexidata 3400 frame store memory. This memory is arranged in a 640 x 512 x 16 bit configuration. Images are displayed simultaneously on two high resolution monitors, one color and one black and white. Interaction with the memory is obtained using a Nova 4 (32K) computer and a trackball and switch unit provided by Lexidata.The language used is BASIC and uses a variety of assembly language Calls, some provided by Lexidata, but the majority written by students (D. Kopf and N. Townes).

Reclamation System

Much progress has been made in recent years towards the development of closed-loop foundry sand reclamation systems. However, virtually all work to date has determined the effectiveness of these systems to remove surface clay and metal oxide scales by a qualitative inspection of a representative sampling of sand particles. In this investigation, particles from a series of foundry sands were sized and chemically classified by a Lemont image analysis system (which was interfaced with an SEM and an X-ray energy dispersive spectrometer) in order to statistically document the effectiveness of a reclamation system developed by The Pangborn Company - a subsidiary of SOHIO.The following samples were submitted: unreclaimed sand; calcined sand; calcined & mechanically scrubbed sand and unused sand. Prior to analysis, each sample was sprinkled onto a carbon mount and coated with an evaporated film of carbon. A backscattered electron photomicrograph of a field of scale-covered particles is shown in Figure 1. Due to a large atomic number difference between sand particles and the carbon mount, the backscattered electron signal was used for image analysis since it had a uniform contrast over the shape of each particle.
