Colorectal cancer (i.e., cancer of the colon or rectum) is one particularly important type of human cancer. Colorectal cancer is the second most common cause of cancer mortality in adult Americans (Landis, et al., 1999, CA Cancer J Clin, 49:8-31). Approximately 40% of individuals with colorectal cancer die. In 2001, it is estimated that there will be 135,400 new cases of colorectal cancer (98,200 cases of colon and 37,200 cases of rectal cancer) and 56,700 deaths (48,000 colon cancer and 8,800 rectal cancer deaths) from the disease (American Cancer Society). As with other cancers, these rates can be decreased by improved methods for diagnosis.
Although methods for detecting colon cancer exist, the methods are not ideal. Digital rectal exams (i.e., manual probing of rectum by a physician), for example, although relatively inexpensive, are unpleasant and can be inaccurate. Fecal occult blood testing (i.e., detection of blood in stool) is nonspecific because blood in the stool has multiple causes. Colonoscopy and sigmoidoscopy (i.e., direct examination of the colon with a flexible viewing instrument) are both uncomfortable for the patient and expensive. Double-contrast barium enema (i.e., taking X-rays of barium-filled colon) is also an expensive procedure, usually performed by a radiologist.
Because of the disadvantages of existing methods for detecting colon cancer, new methods are needed. The present embodiments relate to a lifting drive for a radiation filter in a mammography device. The present embodiments also relate to a mammography device with a lifting drive.
Mammography devices may be used for fluoroscopy of an object to be examined, for example, a female breast. Mammography devices may feature a radiographic source and a radiation detector. The object to be examined is positioned between the radiographic source and the detector. Scattered radiation is predominantly caused by deflection of the examination rays in the x-rayed object under examination. Scattered radiation is especially problematic when x-raying thicker objects. To reduce the radiation scattering at the detector, an anti-scatter grid is usually arranged behind the object under examination and in front of the detector.
Anti-scatter grids may cause stripes or grids of noise on the examination image recorded in the detector. To reduce or eliminate these disturbance stripes, the anti-scatter grid is

Digital rectal exams (i.e., manual probing of rectum by a physician), for model, although relatively inexpensive, are unpleasant and can be inaccurate. Fecal occult lineage testing (i.e., detection of blood in stool) is nonspecific because rake in the stool has multiple causes. Colonoscopy and sigmoidoscopy (i.e., direct examination of the colon with a elastic viewing instrument) are both uncomfortable for the patient and expensive. Double - contrast barium enema (i.e., taking X - rays of barium - filled colon) is also an expensive procedure, usually performed by a radiologist. 
 Because of the disadvantages of existing methods for detecting colon cancer, fresh methods are needed. The present embodiment relate to a lifting drive for a radiation filter in a mammography device. The present embodiments besides relate to a mammography device with a lifting campaign. 
 Mammography devices may be used for fluoroscopy of an aim to be examined, for example, a female breast. Mammography devices may feature a radiographic source and a radiation detector. The object to be examined is positioned between the radiographic source and the detector. Scattered radiation is predominantly cause by deflection of the interrogation rays in the x - rayed object under examination. Scattered radiation sickness is especially problematic when x - raying thick aim. To reduce the radiation scatter at the detector, an anti - scatter grid is normally arranged behind the object under examination and in front of the detector.
