A compact microwave breast imaging (MBI) Omni-directional antenna applications has been proposed. As a primary health observation, the built antenna is inexpensive and has no health risk. Two antenna designs have been used together with the viable signal processing technology to identify the tumor available in breast phantom. At the 3.3 GHz frequency band, the electric length of the antenna is 0.22 λ × 0.176 λ × 0.0088 λ antenna has been offering the bandwidth is 40.6%.

Set Up

In this paper we consider radar approaches for breast cancer detection. The aim is to give a brief review of the main features of incoherent methods, based on beam-forming and Multiple SIgnal Classification (MUSIC) algorithms, that we have recently developed, and to compare them with classical coherent beam-forming. Those methods have the remarkable advantage of not requiring antenna characterization/compensation, which can be problematic in view of the close (to the breast) proximity set-up usually employed in breast imaging. Moreover, we proceed to an experimental validation of one of the incoherent methods, i.e., the I-MUSIC, using the multimodal breast phantom we have previously developed. While in a previous paper we focused on the phantom manufacture and characterization, here we are mainly concerned with providing the detail of the reconstruction algorithm, in particular for a new multi-step clutter rejection method that was employed and only barely described. In this regard, this contribution can be considered as a completion of our previous study. The experiments against the phantom show promising results and highlight the crucial role played by the clutter rejection procedure.

AimTo measure the knowledge, perceptions, and practices of Jordanian primary healthcare practitioners (PHCPs) (physicians, nurses, midwives, and nurse aids) employed in Jordanian Ministry of Health (MoH) primary health clinics with respect to counseling on cancer (cancer screening, the signs and symptoms of cancer, and referral for specialized care).BackgroundIntegration of oncology services within primary care is a means of enhancing cancer early detection, and requires involvement of skilled. In the Middle East, little is known about PHCPs’ potential to be providers of such services.MethodsA questionnaire measuring PHCP perceptions and practices related to counseling on cancer screening and diagnosis was distributed to PHCPs across MoH clinics covering the main regions of Jordan.FindingsA total of 322 practitioners responded (75.1% response). Across most activities involving cancer detection, no more than 30% reported performing activities. Roughly half of PHCPs expressed discomfort at providing cancer-related counseling and at least 43% of non-physicians expressed limited confidence in cancer-related counseling. Confidence was a consistent predictor of provision of counseling and confidence in turn was associated with having greater knowledge, having positive a valuation of counseling, and being a physician. Results reveal points where educational efforts can strengthen PHCPs’ provision of cancer control-related services.

AbstractThis paper investigates the potential of magnetic modulated iron oxide nanoparticles in terms of a contrast enhancement for Ultra-wideband (UWB) breast imaging. The work is motivated by the low dielectric contrast between tumor and normal glandular/fibroconnective tissue. The influence of an external polarizing magnetic field on pure and coated magnetite nanoparticles is investigated in this contribution. Measurements were conducted using M-sequence UWB technology and an oil-gelatin phantom. It is shown that a coating, which is necessary for clinical use, results in a lower signal response, and thus leads to a lower detectability of magnetic modulated nanoparticles.

Reconstructed Breast

Advances in breast imaging over the last 15 years have improved early breast cancer detection and management. After treatment for breast cancer, many women choose to have reconstructive surgery. In addition, with the availability of widespread genetic screening for breast cancer, an increasing number of women are choosing prophylactic mastectomies and subsequent breast reconstruction. The purpose of this pictorial essay is to present the spectrum of imaging findings in the reconstructed breast.

Abstract Ultrasound is used for breast cancer detection as a technique complementary to mammography, the standard screening method. Current practice is based on reflectivity images obtained with conventional instruments by an operator who positions the ultrasonic transducer by hand over the patient’s body. It is a non-ionizing radiation, pain-free and not expensive technique that provides a higher contrast than mammography to discriminate among fluid-filled cysts and solid masses, especially for dense breast tissue. However, results are quite dependent on the operator’s skills, images are difficult to reproduce, and state-of-the-art instruments have a limited resolution and contrast to show micro-calcifications and to discriminate between lesions and the surrounding tissue. In spite of their advantages, these factors have precluded the use of ultrasound for screening. This work approaches the ultrasound-based early detection of breast cancer with a different concept. A ring array with many elements to cover 360◦ around a hanging breast allows obtaining repeatable and operator-independent coronal slice images. Such an arrangement is well suited for multi-modal imaging that includes reflectivity, compounded, tomography, and phase coherence images for increased specificity in breast cancer detection. Preliminary work carried out with a mechanical emulation of the ring array and a standard breast phantom shows a high resolution and contrast, with an artifact-free capability provided by phase coherence processing.
