The existing colposcope has served its purpose well; however, it has had its limitations with what can be seen through the cumbersome use of the duck-bill speculum. The Veda-Scope Mk II is an all-in-one device that obviates the need for a duck-bill speculum by gently inflating the vagina with air thereby allowing an unobscured view of not only the cervix, but, for the first time, the entire vaginal wall.
The cervix on the home page is an actual image of what can be seen on the high definition monitor. The high definition camera produces 1.6 million MEG resolutions. Note there are no duck bill blades in the way. When the Veda-Scope Mk II speculum is pivoted, any part of the cul de sac can be seen, but, more importantly, with a quick release syringe to spray the entire internal vagina with acetic acid this allows, for the first time, the observation of white patches or spots on the vaginal walls that can be seen just as clear as the cervix on the cover. This is a new level. A foot paddle will allow any image to be taken; in fact, up to 32 can be taken for later analysis. A patient is also able to look at the images in any discussion on what procedures need to be further carried out. In addition, as can be seen on the home page, filters allow a simple switch to green, red or blue light.
The imaging wavelength bands were selected based on in vivo fluorescence spectroscopic studies. The fluorescence images (both LIF image and LIFR image) clearly delineate the abnormal tissue areas for biopsy. Early cancer sites are better visualized under fluorescence imaging than under conventional white light examination. Initial clinical tests demonstrated the usefulness of the imaging prototype system for early detection of cervical and vaginal cancer.
