Problems solved by technology

[0010] A troublesome aspect of the technique described above (which is what the present invention addresses) is that the shape of the breast varies from patient to patient, and especially as the scan progresses from the chest wall towards the nipple, the shape of the breast changes dramatically

Embodiment Construction

[0029] Referring to Figure 1, an optical scanning apparatus 2, such as those described in US Patent Nos. 5,692,511 and 6,100,520, supports a patient 4 on a patient support surface 6, such as a table top. The patient's breast 8 is suspended in the scanning cavity 10, and the detector mechanism 12 revolves along various orbits around the breast. The table top 6 includes an opening 13 through which the breast protrudes into the scanning cavity 10 . The detector mechanism 12 typically orbits 360° around the vertical axis of the scan chamber 10 and moves incrementally vertically (elevating motion) between orbits to sequentially image successive slice planes. This action continues until all slice planes of the subject have been scanned.

[0030] figure 2 A top view of the detector mechanism 12 in FIG. 1 is shown. A laser source 14 illuminates the scan object, for example the breast 8 , at a point 16 . A plurality of detectors 18 define a circular arc around the object to be scan...

Abstract

A diagnostic computed tomographic imaging apparatus, comprises a patient support structure including a tabletop to support a patient in front-down, prone position. The tabletop includes an opening to permit a breast of the patient to be vertically pendant below the tabletop. A scanning mechanism is disposed below the opening and orbitable about the breast pendent through the opening to obtain perimeter data and image reconstruction data of the breast. The scanning mechanism rotates about an axis of rotation transverse to the tabletop. One of the tabletop and scanning mechanism is movable in x-y axes to center the breast about the axis of rotation.

Description

[0001] related application [0002] This application claims priority to US Provisional Patent Application No. 60 / 759,066, filed January 17,2006. technical field [0003] The present invention relates to a diagnostic optical imaging device that employs a near-infrared laser as a radiation source and an array of detectors with a limited field of view directed at the patch on the surface of the scanned object that they occupy to Simultaneously detecting the intensity of light emitted from the object is used to reconstruct an optical cross-sectional image of the object, in particular the object is movable relative to the radiation source and detector array to center the object relative to the scanning mechanism. Background technique [0004] Breast cancer is one of the leading causes of death among American women. If malignant tumors can be detected early, effective treatment of the disease can be easily achieved. The main work being done now is to provide mass screening of pe...
