This study is designed to evaluate the information provided to the clinicians by the surgical imaging device. It is also to gain insight on the user interface and how "user friendly" it is to the clinician.
Over the last decade, objective ways of measuring tissue oxygen have been introduced into the medical arena and are being used more and more for assessing ischemic events in tissue. Handheld Doppler ultrasound, infrared thermography, polarized spectral imaging, laser Doppler perfusion imaging, and fluorescence imaging have all been used with some degree of success. However, only a few have gained universal acceptance.  Multispectral imaging (MSI) which uses near-infrared (NIR) light to measure tissue oxygen levels in superficial tissue is another method that has been successfully used to assess tissue flap health.
The objective of this study is to conduct an evaluation of superficial tissue with Presygen™/si-1 in various patient types for surgical imaging during breast reconstruction. In addition, participating surgeons will complete a structured survey regarding their assessment of Presygen™/si-1 work station during the surgical procedure.
Primary Goal: Evaluation of superficial tissue in various patient types for surgical imaging during breast reconstruction.
Secondary Goal: Surgeon assessment of surgical work station during surgery through a prepared questionnaire.

Complications that affect patients during surgery. They may or may not be associated with the disease for which the surgery is done, or within the same surgical procedure.
The chilling of a tissue or organ during decreased BLOOD perfusion or in the absence of blood supply. Cold ischemia time during ORGAN TRANSPLANTATION begins when the organ is cooled with a cold perfusion solution after ORGAN PROCUREMENT surgery, and ends after the tissue reaches physiological temperature during implantation procedures. WARM ISCHEMIA TIME starts then and ends with completion of SURGICAL ANASTOMOSIS.
A method of delineating blood vessels by subtracting a tissue background image from an image of tissue plus intravascular contrast material that attenuates the X-ray photons. The background image is determined from a digitized image taken a few moments before injection of the contrast material. The resulting angiogram is a high-contrast image of the vessel. This subtraction technique allows extraction of a high-intensity signal from the superimposed background information. The image is thus the result of the differential absorption of X-rays by different tissues.
Pathologic processes that affect patients after a surgical procedure. They may or may not be related to the disease for which the surgery was done, and they may or may not be direct results of the surgery.
Neoplasm drug therapy involving an extracorporeal circuit with temporary exclusion of the tumor-bearing area from the general circulation during which high concentrations of the drug are perfused to the isolated part.
Surgery is a technology consisting of a physical intervention on tissues. All forms of surgery are considered invasive procedures; so-called "noninvasive surgery" usually refers to an excision that does not penetrate the structure being exci...
Radiology is the branch of medicine that studies imaging of the body; X-ray (basic, angiography, barium swallows), ultrasound, MRI, CT and PET. These imaging techniques can be used to diagnose, but also to treat a range of conditions, by allowing visuali...
