چکیده
We assess the application of microwave tomography (MWT) for detection axillary lymph nodes (ALNs) in breast cancer patients. numerically study effects limiting angular view MWT, as probes can only be placed on a limited arc around region. also possibility increasing amount retrievable information by acquiring data two consecutive steps, with single antenna set different positions. finally experimentally test MWT anthropomorphic phantoms levels anatomical fidelity, and ALN Our system (0.8–2.5 GHz) employs six monopole antennas transverse plane, facing The reconstruction algorithm implements distorted Born iterative method, combined two-step shrinkage/thresholding inversion (DBIM-TwIST). numerical results i) highlight challenges associated view, ii) show that performing measurements enhances imaging results, suggesting rotating between is an effective means to increase MWT. experimental our detect To best knowledge this first paper realistic 3-D scenario.

Prediction Axillary Lymph Node Involvement Status on Breast Cancer Data
Introduction: one of the foremost usual methods for evaluating breast cancer is the removal of axillary lymph nodes (ALN) which include complications such as edema, limited hand movements, and lymph accumulation. Although studies have shown that the sentinel gland condition represents the axillary nodules context in the mammary gland, the efficacy, and safety of the guard node biopsy need to be...

متن کاملLymph node shape in computed tomography imaging as a predictor for axillary lymph node metastasis in patients with breast cancer
The aim of the present study was to evaluate whether preoperative computed tomography (CT) is a useful modality for the diagnosis of axillary lymph node metastasis. The axillary lymph node status was examined in patients with primary breast cancer who had undergone surgery. In total, 75 patients were analyzed with preoperative contrast CT images, following which the patients underwent an intrao...
متن کاملAxillary lymph node dissection on the run?
The standard approach of performing a completion axillary lymph node dissection (cALND) after a positive sentinel node for breast cancer patients is no longer generally accepted. This study applied the criterion of a 27% risk of having residual positive lymph nodes calculated by the MD Anderson nomogram to perform a cALND. This 27% cut-off is based on the number of positive non-sentinels in the...
متن کاملthe accuracy of sentinel lymph node biopsy compared with axillary lymph node dissection in breast cancer
background : sentinel lymph node biopsy is used as an accurate staging procedure to detect early breast cancer. several studies have documented that sentinel lymph node biopsy can accurately determine the status of axillary nodes. sentinel node biopsy offers the advantage of accurately staging the axilla and eliminating the need for a full axillary dissection for patients who have a negative se...
