Objective assessment of aesthetic outcomes of breast cancer treatment: quantifying aesthetic factors after breast reconstruction / Quantifying aesthetic factors after breast reconstruction

Kim, Min Soon, 1974- 28 August 2008 (has links)
Breast cancer is the most common cancer among American women. One in eight women will be diagnosed with breast cancer during her lifetime. Essentially all breast cancer treatment involves surgery. The two most generally performed surgical treatments for breast cancer are breast conservation therapy and mastectomy followed by breast reconstruction. Breast reconstructive surgery is an important component of the breast cancer treatment process. The aesthetic outcome of breast cancer treatment is a critical factor in breast cancer survivors' quality of life. Aesthetics is a general term that refers to physical characteristics such as symmetry and proportion. Currently, physicians, patients, or other observers evaluate breast aesthetics in a subjective, qualitative manner. However, such assessments are typically based on vaguely defined rating scales that have low intra- and inter-observer agreement. Their qualitative nature also restricts the analyses that can be performed. Quantitative, objective measures with high reliability are needed to meaningfully relate patient and surgical variables to aesthetic outcomes and to compare the outcomes of different kinds of breast cancer treatments (e.g., reconstruction procedures). I postulated that quantitative measures of breast aesthetic properties can be designed using clinical photographs. In this dissertation, I have designed algorithms to compute objective, quantitative, reproducible measures of breast aesthetics. I have evaluated the algorithms for computing objective measures of breast aesthetic properties such as ptosis and surgical scars from clinical photographs. A preliminary observer rating scale of 11 symmetry ratings items, 14 individual breast ratings items, and a global rating on overall appearance before and after the entire rating items was proposed. Eye-tracking technology was used to understand how plastic surgeons assess breast aesthetics by recording their gaze path while they rate breast anatomy on clinical photographs. In addition to these design and evaluation tasks, I also have used the objective measures to conduct a preliminary comparison of the aesthetic outcomes of different reconstruction procedures. / text

Guidelines for smartphone usage in telemedical photography / Riktlinjer för användning av smartphones inom telemedicinsk fotografering

Hagman, Anna, Riedberg, Sander January 2014 (has links)
The wide usage of smartphones makes them an interesting and potential medical device. Given that smartphone cameras have a sufficiently high quality - some of the medical photography done at health care facilities could be done telemedically and by non-medically educated per- sons. Therefore a research of the quality of the photos taken with smartphone cameras has been done. This thesis presents guidelines regarding how inexperienced persons could take high qualitative medical photos with a smartphone. This thesis includes a review of current guidelines within medical photography. A compari- son between two popular smartphones and a professional medical camera has been done - where possibilities and limitations in smartphone cameras have been identified. In order to evaluate the sharpness and the color temperature representation in the photos taken with smartphones, an experiment with realistic lighting and easy accessible color-calibration cards has been done. The execution and the achieved result have formed the basis of the proposed guidelines. The result shows that smartphone cameras are of high quality and thereby could be used as a complement to advanced medical camera equipment. With the help of the proposed guidelines inexperienced persons could acquire sufficiently good medical photos, in order to be used as diagnostic material. This thesis provides a foundation for further research and implementation within the area, with the purpose of becoming an important part of the efficiency improvement within the telemedical health care.

PSICOLOGIA DELLA PERCEZIONE ED ESTETICA DEL MOVIMENTO IN FRANCIA (1875-1905). UN'ARCHEOLOGIA DELL'ESPERIENZA CINEMATOGRAFICA / Psychology of perception and aesthetics of movement in France (1875-1905). An archaeology of cinematic experience

GROSSI, GIANCARLO MARIA 08 March 2016 (has links)
In Francia, tra la fine del XIX e l’inizio del XX secolo, sorge una nuova forma esperienziale, quella del cinema. Nello stesso contesto, il movimento corporeo diventa oggetto di studio da parte di una serie di discipline, in particolar modo l’estetica e la psicofisiologia, che si ridefiniscono reciprocamente in un costante dialogo con le nuove tecnologie visive. Esiste una relazione tra questi due eventi? Il presente lavoro mira a costruire un’archeologia dell’esperienza cinematografica attraverso l’analisi dei testi di estetica sperimentale, psicologia della percezione e neurologia che emergono nell’orizzonte culturale francese tra il 1875 e il 1905. Il primo capitolo si concentra sulle teorie estetiche di Guyau, Séailles e Souriau, in cui la bellezza del movimento è concettualizzata seguendo un processo di progressiva meccanizzazione del corpo. Nel secondo capitolo viene analizzato il dibattito psicologico interno alla «Revue Philosophique» (1876), dove il corpo diviene medium capace di rendere visibile e registrabile il mondo soggettivo. Infine, nel terzo capitolo vengono studiate le ricerche estetiche e iconografiche che hanno luogo presso la clinica della Salpêtrière diretta da Charcot, pubblicate nella «Nouvelle Iconographie» (1888). Da queste, nasce una nuova morfologia del corpo in movimento, sostenuta dal progresso dei metodi grafici fino all’avvento del cinema. / In France, between the late nineteenth and the early twentieth century, a new experience rises, that of cinema. In the same context, the bodily movement becomes the object of study of a huge range of disciplines, especially aesthetics and psychophysiology, which redefine each other in a constant dialogue with new visual technologies. Is there a relationship between these two events? This work aims to build an archaeology of the cinematic experience through the analysis of texts of experimental aesthetics, psychology of perception and neurology that emerge in the French cultural context between 1875 and 1905. The first chapter focuses on the aesthetic theories of Guyau, Séailles and Souriau, where the beauty of movement is conceptualized following a process of gradual mechanization of the body. The second chapter analyzes the psychological debate inside the «Revue Philosophique» (1876), where the body becomes a medium capable of making the subjective world visible and adjustable. Finally, in the third chapter we investigate the aesthetic and iconographic researches that took place in Charcot’s clinic at the Salpêtrière, published in the «Nouvelle Iconographie» (1888). From these arises a new morphology of the body in motion, supported by the progress of graphical methods until the advent of cinema.

Préserver la santé des armées dans le Japon moderne : la médecine militaire face à la guerre russo-japonaise / Preserving the health of the army in Modern Japan : military medicine in the Russo-Japanese War

Daimaru, Ken 16 December 2017 (has links)
Cette thèse consiste à interroger les expériences de la guerre russo-japonaise (1904-1905), en rapprochant deux objets historiques : l'histoire de la guerre et l'histoire de la médecine. Son objectif est de documenter et d’analyser l'organisation du Service de santé de l’armée impériale japonaise et les pratiques médicales qui en déroulent au tournant du vingtième siècle. En examinant la professionalisation de la médecine militaire pendant l’ère Meiji (1868–1912) et son implication pendant le conflit de 1904-1905, il est question de comprendre la production culturelle des discours, des objets et des images liées aux maladies et aux blessures de guerre. Cette analyse repose sur les regards croisés des différents acteurs (Japonais et observateurs internationaux) sur le corps blessé et malade, que les atteintes soient physiques ou psychiques. Les résultats montrent comment le bouleversement sur le champ de bataille, induit par l’augmentation de la puissance de feu et la réorganisation tactique et stratégique suscitée par cette dernière, est aussi le pendant d’une médicalisation des activités combattantes, de la recherche militaire et de la production d’expertises. Le paradigme du « combat asceptique » et le succès de la lutte contre les maladies servent à légitimer le rôle de la médecine dans les armées. Par ailleurs, la transformation des formes de violence de guerre accentue aussi la fragilité des médecins sur le champ de bataille, où les effets de l’industrialisation progressent. À l’épreuve de la professionnalisation, de la spécialisation et des pratiques individuelles, cette thèse discute les apports et les limites des stratégies adoptées par les médecins japonais pour préserver la santé des armées face à la violence de la guerre industrielle. / This thesis analyses the experiences of the Russo-Japanese War (1904-1905), bringing together two historical objects of inquiry: the history of warfare and the history of medicine. Its purpose is to document and understand the organization of the Imperial Japanese Army Sanitary Corps and the medical practices that unfolded within it at the turn of the twentieth century. Focusing on the creation and the institutionalization of the care of the war wounded and sick during the Meiji era (1868-1912) and its implications for the conflict of 1904-1905, this thesis highlights the institutional and social dynamics of military medicine and the cultural production of discourses, objects and images related to war diseases and wounds. Our theoretical framework articulates the entanglement of the various actors’ perceptions (Japanese doctors and international observers) on the wounded and/or diseased body. Our results show how the transformation of the battlefield, induced by increased firepower and the resulting tactical and strategic reorganization, was also a driving force for the medicalization of combat activities, military research and the production of expertise. These processes reshaped the paradigms of combat aimed at maintaining the competitiveness of the military, that the success of preventive medicine serves to legitimize. They also accentuate the fragility of the army and the structure of medicine on the battlefield, which were under increasing stress due to the rapid progress of industrialization. The professional specialization and individual practices observed during the war lead us to discuss the benefits and limits of the strategies adopted by Japanese military surgeons to resist the increasingly destructive realities of industrial warfare.
