Embodiment Construction

[0026] US5692511, US6100520 and US6130958 all disclose a medical optical imaging device, which are hereby incorporated by reference.

[0027] Such as figure 1 As shown, the patient 2 is lying face down on the scanning table 4 , with the breast 6 hanging in the scanning cavity 8 . The medical optical imaging device 10 includes a collimator 12 fixed on an orbiting plate 14 and a lifting plate 16 . Collimator 12 links with detector 13 (see Figure 5 ). The orbiting plate 14 is rotated in a circle around the breast to obtain a portion of the data. The drive screw 18 moves the lift plate 16 vertically to position the orbiting plate 14 at different vertical positions and rotates in a circle around the breast in this position to obtain another portion of the data. The side barrier 20 is fixed on the lower side of the scanning table 4 and the lifting plate 16, thereby providing an external light for the scanning cavity 8 composed of the side barrier 20, the orbiting plate 14, the ...

Abstract

A scanner (10) for a medical optical imaging device, comprises an illumination source positioned to direct emitted light (40) into a breast (6) positioned below a support surface; a plurality of detectors (13) positioned to detect light emerging from the breast; and a container (21) disposed below the illumination source and the detectors (13) adapted to trap light reflected from the breast.

Description

[0001] related application [0002] This is a non-provisional application claiming priority from US Provisional Application 60 / 197,415, filed April 14, 2000, which is hereby incorporated by reference. technical field [0003] The present invention relates to a medical diagnostic imaging device, and more particularly, the present invention relates to a mammography device using a near-infrared laser as a radiation source. Background technique [0004] Breast cancer is a leading cause of death among American women. Early detection of malignant tumors can effectively treat the disease. At present, people mainly focus on the fluoroscopic examination of tumor masses for breast tumor symptom clusters. This fluoroscopic examination requires sophisticated automatic equipment to reliably complete the entire detection process. [0005] The x-ray absorption density resolution of current radiography methods is insufficient for reliable early detection of malignancies. Studies have sho...
