Non-local means (NLM) denoising has become widely accepted as a very effective denoising tool in the image processing community, and has yielded very promising results in lung and abdominal CT. However, NLM requires an... Read More
2011-176 – Calcitonin gene related peptide (CGRP) and Substance P (SP) were elevated in the nasal secretions of patients with postnasal drip who also have chronic cough compared to levels from nasal secretions from patients without cough. A point-of-care test which can assay the level of CGRP and SP may be helpful in predicting whether or not chronic cough is due to postnasal drip.

However, the long imaging time of 5-10... Read More
2010-296 – Communications between electronic components employ one of a number of signaling schemes. Generally, digital communications use one of two classes of signaling schemes: single-ended or differential signaling. A single-ended signaling channel employs transmission of n-level (typically 2-level) signals through a single signal conductor, using a ground or power conductor as the reference for... Read More
2010-294 – In laparoscopic radical prostatectomy (RP), the pedicle is transected, but care must be taken to preserve the adjacent neurovascular bundle. Electrocautery or other hemostatic energy sources are not used due to concerns over collateral thermal damage, adhesives or sutures alone have not been shown to provide reliable hemostatis, and existing clips can be difficult to place and adjust. A... Read More
Transpulmonary Induction of Therapeutic Hypothermia (In Collaboration with Minnesota High-Tech Resources LLC)
2010-284 – Therapeutic hypothermia is a widely accepted methodology for mitigating injury to vital organs following ischemic insults.

This device sits at the abdominal opening and remains stable by means of adhesive tape at the lower rim. There are no robotic mounts or arms holding... Read More
2010-233 – The inner ear vestibular system reflexively controls eye position in the orbits. For example, when the head is tilted to the side (ear moved toward the shoulder) the eyes roll in the opposite direction so that they stay oriented to the horizon. This eye movement is called head tilt induced ocular counter roll and is mediated in part by the otolith organs of the vascular system. Damage to... Read More
2010-220 – Radiation therapy treatment is used in nearly two-thirds of all cancer patients. Accurate targeting of the tumor over the treatment period is critical to effective therapy. Placement of permanent tattoos is the current standard practice to aid in the alignment and targeting of radiation therapy over multiple treatments. Existing tattoo methods involve the use of freehand needle sticks,... Read More
