Enhancing the Visualization of the Peripheral Retina with Wide Field-of-View Optical Coherence Tomography

The goal of my Ph.D. thesis is to enhance the visualization of the peripheral retina using wide-field optical coherence tomography (OCT) in a clinical setting.

OCT has gain widespread adoption in clinical ophthalmology due to its ability to visualize the diseases of the macula and central retina in three-dimensions, however, clinical OCT has a limited field-of-view of 300. There has been increasing interest to obtain high-resolution images outside of this narrow field-of-view, because three-dimensional imaging of the peripheral retina may prove to be important in the early detection of neurodegenerative diseases, such as Alzheimer's and dementia, and the monitoring of known ocular diseases, such as diabetic retinopathy, retinal vein occlusions, and choroid masses.

Before attempting to build a wide-field OCT system, we need to better understand the peripheral optics of the human eye. Shack-Hartmann wavefront sensors are commonly used tools for measuring the optical imperfections of the eye, but their acquisition speed is limited by their underlying camera hardware. The first aim of my thesis research is to create a fast method of ocular wavefront sensing such that we can measure the wavefront aberrations at numerous points across a wide visual field. In order to address aim one, we will develop a sparse Zernike reconstruction technique (SPARZER) that will enable Shack-Hartmann wavefront sensors to use as little as 1/10th of the data that would normally be required for an accurate wavefront reading. If less data needs to be acquired, then we can increase the speed at which wavefronts can be recorded.

For my second aim, we will create a sophisticated optical model that reproduces the measured aberrations of the human eye. If we know how the average eye's optics distort light, then we can engineer ophthalmic imaging systems that preemptively cancel inherent ocular aberrations. This invention will help the retinal imaging community to design systems that are capable of acquiring high resolution images across a wide visual field. The proposed model eye is also of interest to the field of vision science as it aids in the study of how anatomy affects visual performance in the peripheral retina.

Using the optical model from aim two, we will design and reduce to practice a clinical OCT system that is capable of imaging a large (800) field-of-view with enhanced visualization of the peripheral retina. A key aspect of this third and final aim is to make the imaging system compatible with standard clinical practices. To this end, we will incorporate sensorless adaptive optics in order to correct the inter- and intra- patient variability in ophthalmic aberrations. Sensorless adaptive optics will improve both the brightness (signal) and clarity (resolution) of features in the peripheral retina without affecting the size of the imaging system.

The proposed work should not only be a noteworthy contribution to the ophthalmic and engineering communities, but it should strengthen our existing collaborations with the Duke Eye Center by advancing their capability to diagnose pathologies of the peripheral retinal.

DEVELOPMENT OF AN OFF-LINE RAINFLOW COUNTING ALGORITHM WITH TEMPORAL PARAMETERS AND DATA REDUCTION

Rainflow counting methods convert a complex load time history into a set of load reversals for use in fatigue damage modeling. Rainflow counting methods were originally developed to assess fatigue damage associated with mechanical cycling where creep of the material under load was not considered to be a significant contributor to failure. However, creep is a significant factor in some cyclic loading cases such as solder interconnects under temperature cycling. In this case, fatigue life models require the dwell time to account for stress relaxation and creep. This study develops a new version of the multi-parameter rainflow counting algorithm that provides a range-based dwell time estimation for use with time-dependent fatigue damage models. To show the applicability, the method is used to calculate the life of solder joints under a complex thermal cycling regime and is verified by experimental testing. An additional algorithm is developed in this study to provide data reduction in the results of the rainflow counting. This algorithm uses a damage model and a statistical test to determine which of the resultant cycles are statistically insignificant to a given confidence level. This makes the resulting data file to be smaller, and for a simplified load history to be reconstructed.

Manuscript of James Cummings- August 28, 1860

Transcript (spelling and grammar retained): Chippawa [Chippewa] 28th August 1860 My Dear Sir I duly received your very kind letter of the 24th [June] asking me to communicate such facts of general interest connected with my career during the War with the United States. I have no objection to afford you such information as came under my own observation; nevertheless I do so, with the understanding, I have no desire to be my own trumpeter. With respect to your circular wherein you state you have been for several years collecting materials for a History of the late War between the United States & Great Britain, for which you are now gathering further materials to add to your collection, concerning the Second War for Independence. I am rather at a loss to know, what is meant by the second war; If you allude to the petty Rebellion, it could not be called a War, Those that caused the outbreak were very soon put down, by the Loyal people of the Province without the aid of Regular Troops being satisfied with the Independence they enjoyed. With respect to the several questions names in your circular: To the 1st I would say, this locality is made memorable by the battle of Chippawa [Chippewa] which took place about a mile above the village on the ground I pointed out to you, when I had the pleasure of seeing you a few days ago, with Mr Porter of the Niagara Falls, of which I believe you took sketches at the time. 2nd I have no historical documents of any value; so many years having gone past, the most of my old papers have either been lost or destroyed, I however came across two letters, one dated Queenston 9th July 1812 from Lt. Col. Nicholl Quarter Master General of Militia, the other from Lt. Col Myers Deputy Quarter Master General of the Regular Army date Fort George 23rd same month, directed to me in the hand writing of each of those officers as Deputy Quarter Master General of Militia, which letters I shall be obliged you would return at as early a day possible, as I wish to place them with tome others in the case, I have had made to hold the cocked hat & feather I wore during that eventful period, which I am sorry I did not exhibit when you was at my house; with reference to it I now enclose a letter from Lt. Col. Clark, residing at Port Dalhousie he was Captain & Adjutant of Militia in the War of 1812__ I send the letter in proof of the cock’d hat it is a lengthy one, but you may find time to turn over it, as I shall also place it in the hat case__ 3rd Where are [but] [for] traditionary [sic] witnesses residing in this vicinity – Col Clark above named Mr Merritt of St. Catharines, & Mr Kerby of Brantford are the only ones I now recollect, who could offord [sic] you any statistical information. 4th I have no pictorial sketches of any Military Movements or fortifications. As regards my own career, which you appear [ ? ] of knowing__ I was first a Lieutenant in a volunteer flank company stationed on the river side opposite [Navy] Island not far from the battle ground of Chippawa [Chippewa], I got promotion as Lieutenant of Cavalry before I got my Cavalry dress completed in three days more, I was called by General Brock to Fort George, was appointed Deputy Quarter Master General of Militia with the rank of Captain s the accompanying letters will show. I was at the battle of Stony Creek, several skirmishes at the Cross Roads, when the American army [ ? ] Fort George, at the taking of Col. Boerstler at the Beaver Dam, & had the honor of receiving Colonel Chapens sword at the surrender, who commanded a company of volunteer Horse Men was at the taking of 15 regulars & two officers at Fort Schlosser—was with Col. Bishop at the taking of Black Rock, near him when he fell, three men of the 8th Reg. more killed in the Boat I was in – I was at Chippawa battle, and the last, not the least in Lundy’s lane battle, which the Americans call the battle of Bridge [Waters]. I had forgot; there was another small affair at Corks Mill where I was. I could write a little history of events, but have not the time to do so. If what I have stated will be of any service for the purpose you require I shall feel happy. The history of the late War was published at Toronto in the Anglo American Magazine. Did you ever see it, I have the Books, there were however several errors which came under my notice, which I could have corrected. If my time would permit I could give you a more detailed statement of events. I trust however you may succeed with your publication , and I shall be most happy to hear from you at all times—I related many little occurances verbally to you when here, which I thought not necessary to repeat again as you would have a perfect recollection of them. Be pleased to return the letters for the purpose I require them. I am My Dear Sir Your respectful friend James Cummings

Nutrition et état de santé : études paléochimique et paléopathologique de la population exhumée du cimetière protestant Saint-Matthew, ville de Québec, Canada (1771-1860)

Quatre-vingt-quinze squelettes humains issus des fouilles archéologiques du cimetière protestant Saint-Matthew (ville de Québec, 1771-1860) ont été étudiés en associant deux aspects de la paléonutrition : la paléochimie et la paléopathologie. Le but de cette recherche est d’explorer la relation entre nutrition et état de santé pour cette population préindustrielle. Des informations directes sur l’alimentation ont été recueillies par l’analyse des isotopes stables du carbone et de l’azote du collagène des os, et des informations indirectes ont été obtenues par une quantification de l’état de santé des individus. Les méthodes paléopathologiques utilisées sont celles de l’« indice de santé » (Steckel et al., 2002) pour la comparaison interpopulationnelle, puis des méthodes comprenant des degrés de sévérité plus précis afin d’étudier les variations intrapopulationnelles. L’analyse de ces données atteste d’un état de santé relativement mauvais par comparaison avec d’autres groupes nord-américains contemporains, malgré une alimentation similaire. Des différences alimentaires ont été observées en fonction des données paléodémographiques (âge, sexe), mettant notamment en évidence une variabilité temporelle dans la réalisation du processus de sevrage. De plus, un régime alimentaire moins riche en ressources C4 (maïs, sucre de canne) et en ressources animales (viande, poissons, produits laitiers) a été constaté pour les enfants entre 2 et 7 ans par rapport aux individus plus vieux. Enfin, une relation possible entre la sévérité de certaines pathologies (cribra orbitalia et périostite) et la consommation des ressources alimentaires en C4 et/ou marines et riches en protéines a été observée.

Essai de détection de processus migratoires à travers les isotopes de strontium et d’oxygène : étude des restes humains du cimetière Saint-Matthew (Québec, 1771-1860)

Afin de distinguer les immigrants de première génération des individus nés à Québec et de discuter de l’identité des immigrants de cette ville aux XVIIIe et XIXe siècles, trente-quatre squelettes humains exhumés du cimetière protestant Saint-Matthew (Québec, 1771-1860) ont fait l’objet d’analyses ostéologiques et isotopiques du strontium (87Sr/86Sr) et de l’oxygène (δ18O). Les teneurs obtenues, bien que moins précises que les données historiques, ont permis de distinguer trois groupes d’origine, soit les individus nés à Québec (N = 12), les immigrants de première génération provenant le plus probablement des îles Britanniques et du nord de la France (N = 19) et les immigrants de première génération dont l’origine ne peut être précisée (N = 3). De plus, l’origine écossaise de certains individus a pu être suggérée en fonction de compositions isotopiques variant entre -10,0 et -9,09 % vs VSMOW. La comparaison des groupes d’origine à des données provenant de sources historiques et d’une étude antérieure a permis de dresser un portrait de l’identité des immigrants, à la fois sur les plans populationnel et individuel. De plus, les compositions isotopiques (δ18O, 87Sr/86Sr, δ13C et δ15N) nous laissent croire qu’au moins un individu pourrait être d’origine amérindienne et qu’un autre proviendrait d’une partie de l’Europe plus appauvrie en 18O (possiblement un pays scandinave ou une région alpine). La distribution spatiale des sépultures nous a également permis d’émettre des hypothèses sur les liens familiaux et sociaux d’immigrants inhumés en caveaux ou entassés de façon particulièrement modeste.
