“…Optical and hyperspectral camera based techniques have been developed [13], measuring transverse stretching of a lesion for an applied load but, as the camera presents clinical privacy issues this method may face pushback from clinicians and patients when moved from academia to industry.…”

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.

“…Hyperspectral imaging (HIS) [37][38][39] has been recently applied to characterize canine mammary tumours of unknown histopathology (pre-surgery) and to correlate the results with the post-surgical histopathology outcomes. HIS allows for acquiring hundreds of images in many adjacent narrow spectral bands and compressing them into a single file-the hypercube.…”

Breast cancer frequency in human and other mammal female populations has worryingly increased lately. The acute necessity for taxonomy of the aetiological factors along with seeking for new diagnostic tools and therapy procedures aimed at reducing mortality have yielded in an intense research effort worldwide. Surgery is a regular method to counteract extensive development of breast cancer and prevent metastases provided that negative surgical margins are achieved. This highly technical challenge requires fast, extremely sensitive and selective discrimination between malignant and benign tissues even down to molecular level. The particular advantages of Raman spectroscopy, such as high chemical specificity, and the ability to measure raw samples and optical responses in the visible or near-infrared spectral range, have recently recommended it as a means with elevated potential in precise diagnostic in oncology surgery. This review spans mainly the latter 10 years of exceptional efforts of scientists implementing Raman spectroscopy as a nearly real-time diagnostic tool for clean margins assessment in mastectomy and lumpectomy. Although greatly contributing to medical discoveries for the wealth of humanity, animals as patients have benefitted less from advances in surgery diagnostic using Raman spectroscopy. This work also dedicates a few lines to applications of surface enhanced Raman spectroscopy in veterinary oncological surgery.

“…In recent years, HSI has been widely used to image human and animal tumors in brain [8,9,[11][12][13][14][15][16][17][18][19][20][21][22], breast [8,9,11,[23][24][25][26][27][28], colon [8,9,11,[29][30][31][32][33], prostate [8,9,11,34,35] and skin [8,9,11,[36][37][38][39][40][41][42]. The main shortcoming of most studies utilizing HSI is that they analyze images of histopathological slides to detect tumor cells ex vivo.…”
