Advances in medical imaging technology have led to the acquisition of large number of images in different modalities. On some of these images the boundaries of key organs need to be accurately identified for treatment planning and diagnosis. This is typically performed manually by a physician who uses prior knowledge of organ shapes and locations to demarcate the boundaries of organs. Such manual segmentation is subjective, time consuming and prone to inconsistency. Automating this task has been found to be very challenging due to poor tissue contrast and ill-defined organ/tissue boundaries. This dissertation presents a genetic algorithm for combining representations of learned information such as known shapes, regional properties and relative location of objects into a single framework in order to perform automated segmentation. The algorithm has been tested on two different datasets: for segmenting hands on thermographic images and for prostate segmentation on pelvic computed tomography (CT) and magnetic resonance (MR) images. In this dissertation we report the results of segmentation in two dimensions (2D) for thermographic images; and two as well as three dimensions (3D) for pelvic images. We show that combining multiple features for segmentation improves segmentation accuracy as compared with segmentation using single features such as texture or shape alone.

This study evaluated the effects of a partial glossectomy on: (1) tongue velocity, movement range, and height during speech and (2) vowel production. Videofluoroscopy and cine-MRI of single German words were used to study pre- and postoperative tongue movement in seven glossectomees. Postoperative principal component analyses demonstrated reduced complexity of lingual movement. For the videofluoroscopic data, four of the five patients exhibited reduced postoperative tongue velocity, while one patient exhibited a postoperative increase. Patients produced the words with a slower speech rate after the surgery. The mean differences between pre- and postoperative average tongue height and movement range were small and variable. The cine-MRI data did not indicate a change in postoperative tongue movement range and height. The acoustic results indicated that the vowel /u/ was produced with a more neutral tongue position, postoperatively. The present study demonstrated how tongue movement can be analyzed quantitatively based on videofluorospcopy and cine-MRI.

The aims of this work are:1. To provide the normal cervical and coelomic radiographic appearance of the Loggerhead sea turtle, in the dorso-ventral view, as well as other useful landmarks, to allow for correlation of shell scutes with internal anatomic structures. 2. To provide the normal radiographic anatomy of the limbs of the Loggerhead sea turtle in combination with data obtained from computed tomography - osteological, gross anatomical and histological data.3. To describe the normal ultrasonographic appearance of cervical structures and coelomic organs of the Loggerhead sea turtle, and to provide the respective images of frozen cross-sections for anatomical reference.4. To provide normal computed tomographic images of the vertebral column and coelomic structures of the Loggerhead sea turtle, by establishing reference standards for organ size and position in this species; to provide images of virtual tracheo-bronchoscopy and 3D reconstructions of the respiratory tract and bone structures.5. To provide the normal magnetic resonance imaging (MRI) appearance of coelomic structures of Loggerhead sea turtles in T1 and T2-weighted scans via comparison with cross-sectional anatomic sections of this species.
