Acetowhitening Display Software for Cervical Colposcopic Examination

New software digitizes and memorializes acetowhitening to enhance physicians' viewing during cervical colposcopic exams.

The ImageSense software, available for the UltraSightHD digital colposcopy system, produces a digital output that depicts color differences of the cervix before and after the application of acetic acid during a colposcopic exam. By digitizing and memorializing an otherwise transient effect, and enabling on-demand viewing of the acetowhite process, the image can be used by clinicians to identify areas of the cervix possibly containing disease.

The UltraSight HD Digital Colposcopy System possesses an intuitive touch screen interface that offers an optimal viewing angle and an on screen display (OSD) menu that enables users to annotate high-definition (HD) images, and then save them as part of the electronic health record (EHR). An adaptable viewing screen controlled by the physician enables the patient to also see what the physician sees. The ImageSense software and the UltraSightHD digital colposcopy system are products of STI Medical Systems (Honolulu, HI, USA), and have been approved by the US Food and Drug Administration (FDA).

"Its high-definition imagery takes wonderful ‘archive quality' cervical exam images, and the ability to perform annotations during the exam on the device's touch screen saves physician time,” said Nathan Fujita, MD, of The Queen's Medical Center (Honolulu, HI, USA).

Acetowhitening refers to the blanching of skin or mucous membranes after application of 3% to 5% acetic acid solution, and indicates increased cellular protein and increased nuclear density. It is used particularly on genital skin and mucous membranes, including the uterine cervix, to identify zones of squamous cell change for biopsy and condyloma acuminatum for treatment.
