“…More traditional methods of measuring elasticity using mechanically driven palpating elements [14] show more promise in terms of public acceptance however, the limitation of the 4x4 mobile tactile element array reduces the available spatial resolution compared with the fixed element implementation [8] with a 12x16 fixed element array in a similar area. This means that though an absolute elasticity value is obtained, size and shape information is lost which are each important diagnostic metrics [15].…”

Objective: This paper presents a novel soft tissue elasticity measurement technique based on the fusion of Magnetic, Angular Rate, and Gravity (MARG) sensors and fixe d tactile sensors. This work is intended both as a stand-alone technology, and as an extension of traditional tactile imaging of the breast to allow for accurate diagnosis of breast lesions. Methods: A series of artificial silicone materials known to imitate soft biological breast tissues are characterised using the proposed system and compared against an Instron® universal testing machine to determine system accuracy and repeatability. Results: Comparing the characteristics of 10 distinct materials , with elasticities in the range 9kPa to 90kPa, determined by the proposed system to those from the Instron® yields accuracy within 4% over the full-scale range. Interexperimental repeatability is within 1.5%. Conclusion: The proposed system delivers absolute elasticity of materials to within 4% which, whe n combined with its lack of moving parts and low implementation cost, can significantly improve the diagnostic capability of tactile imaging in the clinical environment. Significance: By applying this technique, to determine the background elasticity of breast tissue, in conjunction with the relative lesion elasticity result from tactile arrays, the full non-invasive diagnostic potential of tactile imaging can be realised with the effect of reducing benign biops y rates, secondary care costs, and patient stress.

Introduction: Breast cancer is the most common female cancer worldwide representing nearly a quarter (23%) of all cancers in women. In India, breast cancer is the leading site of cancer. Due to, point of care pre-screening tool operated by community health workers. limitations of resources in India, breast screening is not done at regular intervals and is inaccessible in most parts of the country. The study was conducted with the aim to assess the feasibility of iBreastExam (iBE), a radiation free, painless, portable. Materials and methods: 1300 female subjects, above 30years were enrolled in the study over 6months and underwent both iBE and Clinical Breast Examination. Results: Out of 1420 women who were approached for the study, 1300(91.5%) consented for the study, indicating acceptability rate for the technique. 146(11.2%) women were positive on either or both modalities and underwent breast ultrasonography. 18 patients were found to have significant lesions on USG, for which they underwent breast fine needle aspiration cytology or biopsy and 3 breast cancers were confirmed. All patients who consented for the study, were comfortable taking iBE test due to its radiation free and painless nature. Conclusions: Breast examination by a radiation-free and painless electro-mechanical hand-held breast palpation device (iBreastExam) is socio-culturally acceptable in the rural environment. The device detected all clinically significant lumps. This study highlights the successful implementation of iBreastExam in the community setting and its potential for mass breast cancer screening in rural environment.

“…17 It is important to catch breast cancer at its earlier stage as it leads to better survival rate, reduces the cost of treatment and the overall burden of breast cancer, which is especially needed in developing countries like ours. 19 The iBreast TM has a potential to be a promising tool in providing effective diagnosis after breast examinations even in young women with dense breasts. It can prove to be a boon in low-resource settings in catching breast cancer at its early stages.…”

Background: iBreastTM tool is simple, safe, a handy device which is designed for mass breast cancer screening tool in a community or hospital setting. This study determined the yield and basic characteristics of women attending the breast cancer screening programme. The study also determined the overall experience of women who underwent breast cancer screening using iBreastTM tool.Methods: This study was a multicentric, retrospective observational study conducted in Mumbai, Bangalore, Chennai and Hyderabad as a part of routine work-place breast cancer screening programme supported by Mfine. Screening was done by iBreastTM, which is a hand-held compression device. After proper clinical examination and iBreastTM scanning, results were confirmed by a consultant trained in interpretation of findings. The overall experience of the women who underwent screening was also determined using a questionnaire. Descriptive analysis was carried out by mean and standard deviation for quantitative variables, frequency and proportion for categorical variables. The qualitative assessment and thematic analysis of the qualitative data was done.Results: A total of 1080 eligible female employees were present in the approached IT companies and out of that 451 women (41.75%) had consented and participated in the screening program. The acceptance rate was highest in Bengaluru city (65%) followed by Mumbai (53%), Chennai (33%) and least in Hyderabad (18%). 31 participants documented positive findings had in the scan and were referred for further evaluation. The quantitative and qualitative data determined that iBreastTM scan was highly accepted by all participants. Customer service, screening location and overall experience was deemed good by the participants with an average score of 4.8.Conclusions: The iBreastTM has the potential to be a promising tool in providing effective diagnosis after breast examinations.
