一種精細的膠片-轉(zhuǎn)-數(shù)字計算機輔助檢查(CAD)系統(tǒng)， 能夠?qū)⒁郧暗哪z片轉(zhuǎn)化為數(shù)字形式，從而可以將近期的影像資料與數(shù)字乳房系統(tǒng)進行比較。

通過將前幾年的膠片為基礎(chǔ)的乳房影像進行數(shù)字化，并輸送給用于檢查現(xiàn)在的數(shù)字影像系統(tǒng)的相同觀察平臺，這套叫做TotalLook的新型系統(tǒng)，能夠幫助放射科醫(yī)師逐年比較乳房影像資料，發(fā)現(xiàn)可能的細微的乳腺癌病變。

iCAD公司(Nashua NH, USA)研制開發(fā)了該系統(tǒng)，該公司總裁兼首席執(zhí)行官W. Scott Parr說：“我們相信在2005年9月公布的DMIST[數(shù)字乳房成像掃描篩查檢查]多年臨床研究，將會加速采用數(shù)字乳房影像檢查的步伐，iCAD公司的TotalLook系統(tǒng)為幾乎每一個數(shù)字乳房影像使用者都為碰到的難題--即如何閱讀以前膠片拍攝的資料--提供了一種快速解決方案。”

這種CAD系統(tǒng)將以前的膠片圖像轉(zhuǎn)化為數(shù)字形式，并且自動調(diào)節(jié)數(shù)字圖像正確的顯示在當前使用的數(shù)字乳房影像工作站之上。通過為放射科醫(yī)生提供“總體閱讀”乳房影像檢查患者多年的乳房檢查資料，該系統(tǒng)減少了光盒閃光，免除了在光盒與工作站之間來回切換的需要，加速了工作流程，提高了工作效率，減少了不舒適的感覺。

TotalLook CAD系統(tǒng)包括一套iCAD數(shù)字轉(zhuǎn)換器工作站以及軟件，能夠很方便的比較以前的膠片圖像與當前使用的數(shù)字圖像。 與iCAD的SecondLook CAD系統(tǒng)配套使用，該系統(tǒng)使得婦女健康中心將傳統(tǒng)的膠片資料轉(zhuǎn)變?yōu)閿?shù)字資料變得更加容易。

Digital CAD Mammography System
 
A comprehensive film-to-digital computer-aided detection (CAD) system converts previous film mammograms into digital form for comparison with more recent images from digital mammography systems.

By digitizing and delivering film-based breast images from prior years to the same digital viewing station used to examine current digital mammograms, this new imaging system, called TotalLook, assists radiologists in the important examination step of comparing breast images from year to year to detect potentially subtle changes that may be indicative of breast cancer.

“We believe the DMIST [Digital Mammography Imaging Screening Test] multi-year clinical study, released in September 2005, will accelerate the adoption of digital mammography,” said W. Scott Parr, president and CEO of iCAD, Inc. (Nashua NH, USA), which developed the system. “iCAD’s TotalLook provides an immediate solution to a problem experienced by almost every digital mammography user--how to view prior cases captured on film.”

The CAD system converts prior film images into a digital format and automatically adjusts the digitized images for correct display on the same workstation and in the same context as the current year digital mammogram. By providing radiologists with a “total look” at a mammography patient’s multi-year breast examinations, the system decreases light box glare and eliminates the need to shift back and forth from light box to workstation to speed workflow, improve productivity, and reduce discomfort.

The TotalLook CAD system includes an iCAD digitizer-based workstation and software that makes it easier to compare prior film images with digitally acquired current images. Working in conjunction with iCAD’s SecondLook CAD systems, the system makes it easier for women’s health centers to transition to digital mammography.
