Honors Theses
Kirschner Pins, known as K-wires, are smooth sharp stainless steel pins used in the field of orthopedics to stabilize bone fracture fragments in their correct position until they have fully healed. K-wires are most commonly used for comminuted metaphyseal fractures of the long bones, and fractures of smaller bones such as the phalanges. The wires are inserted into bone via a drill and the ends of the wire are bent and left outside of the body for easy removal once the bone has healed. The surgeon uses x-ray images to guide K-wire insertion, ensure proper internal alignment, and determine if …

Perceptually Improved Medical Image Translations Using Conditional Generative Adversarial Networks, Anurag Vaidya
Honors Theses
Magnetic resonance imaging (MRI) can help visualize various brain regions. Typical MRI sequences consist of T1-weighted sequence (favorable for observing large brain structures), T2-weighted sequence (useful for pathology), and T2-FLAIR scan (useful for pathology with suppression of signal from water). While these different scans provide complementary information, acquiring them leads to acquisition times of ~1 hour and an average cost of $2,600, presenting significant barriers. To reduce these costs associated with brain MRIs, we present pTransGAN, a generative adversarial network capable of translating both healthy and unhealthy T1 scans into T2 scans. We show that the addition of non-adversarial …
Designing A Low-Cost Ultrasound Pulser, Andrea Huey
Designing A Low-Cost Ultrasound Pulser, Andrea Huey
Honors Theses
Ultrasound imaging allows for those studying living beings to see inside a subject without causing it harm. This allows for real-time images to be taken, leading to ease of observational research. However, while this technology is beneficial to those who utilize it, the devices used to create and receive ultrasound pulses can be incredibly complex, allowing for precise adjustment of the output signal and various other functions, and therefore expensive. The focus of this senior project is the design of a low-cost pulser for use with an ultrasound transducer. While it does not have all the high-level functions of the …
Coupling Of Audio Signals Into Afm Images, Matthew Manning
Coupling Of Audio Signals Into Afm Images, Matthew Manning
Honors Theses
It is well known that Atomic Force Microscopy imaging is capable of yielding high resolution results with of surfaces at the nanoscale. However, despite the device capabilities and vast applications, AFM microscopy is possibly the most prone to the creation of image artifacts. AFM imaging can easily, and is often, corrupted by various external forces. The most obvious and measurable form of external interference is of course the presence of ambient noise. Most AFM manufactures attempt to counter the effects of such noise on the imaging process through use of noise-proof or noise-resistant shields that cover the microscope aperture. Without …
