Noncontact diffuse correlation tomography (ncDCT) is an emerging technology for 3D imaging of deep tissue blood flow distribution without distorting hemodynamic properties. To adapt the ncDCT for imaging in vivo breast tumors, we designed a motorized ncDCT probe to scan over the breast surface. A computer-aided design (CAD)-based approach was proposed to create solid volume mesh from arbitrary ...

A 47-year-old woman was referred for the treatment to our Hospital because of a palpable nodule in the upper medial quadrant of her right breast. After tumor excision, pathohistological examination showed a follicular center cell lymphoma grade 2, B-cell type (CD20+, bc16+, CD10+, bcl2+). The final diagnosis was stage IEA primary extranodal non-Hodgkin s breast lymphoma. The involved breast was...

the cytology study is effective and reliable technique in intraoperative consultation. this study was performed to evaluate the accuracy of the cytology study in intraoperative consultation of the breast lesions. 125 specimens of the breast lesions were examined and studied in imam khomeini hospital during the years 1998-99. the sensitivity, specificity and accuracy for cytological method were ...

When we manipulate small objects, our fingertips are generally subjected to tangential torques about the axis normal to the grasp surface in addition to linear forces tangential to the grasp surface. Tangential torques can arise because the normal force is distributed across the contact area rather than focused at a point. We investigated the effects of tangential torques and tangential forces ...

Mammography remians the procedure of choice in screening asymptomatic women for breast cancer. However, in patients with symptoms, other types of imaging play an important role in the detection of malignancies. The high cost and lack of availability of PET and MRI largely precludes the use in this patient population. TI-201 is nbt the imaging agent of choice because of its wash-out and redistri...

‘I’/& paper proposes technique for automaticall~ identifying and modeling the kinematic wwtminta of manipulated objects. The existence of wn.druints is established by examination of the forces and torques normal and tangential to the object’s motion. Constraints are modeled as joints tuith wnfigumtion and history dependent forca. To illustmte these concepts, seveml experimental examples are pre...
