“…Since percutaneous biopsy is faster, less invasive and less expensive than surgical biopsy, imaging-guided needle biopsy has increasingly become an alternative to surgical biopsy, in particular for the histologic assessment of small lesions such as breast tumors [23].…”

The purpose of this study was to develop a robotic system for ultrasound (US)-guided biopsy and to validate the feasibility, accuracy and efficacy using phantom tests. Twenty peas (mean diameter 9.3+/-0.1 mm) embedded within a gel-phantom were selected for biopsy. Once the best access was defined, the position of the US transducer was recorded by an optical tracking system. Positional data of the transducer and the corresponding US image were transferred to the roboter planning system (LINUX-based industrial PC equipped with video capture card). Once the appropriate position, angulation and pitch were calculated, the robotic arm moved automatically with seven degrees-of-freedom to the planned insertion path, aiming the needle-positioning unit at the center of the target. Then, the biopsy was performed manually using a coaxial technique. The length of all harvested specimens was measured, and the deviation of the actual needle tract from the center of the target was evaluated sonographically. In all targets, the biopsy specimen (mean length 5+/-1.2 mm) was harvested with only one needle pass required The mean deviation of the needle tip from the center of the target was 1.1+/-0.8 mm. Robotic assisted biopsies in-vitro using US-guidance were feasible and provided high accuracy.

“…conducted to confirm the proliferation of malignant cells [4]. To enhance sensitivity and specificity of the cancer screening and efficacy of the biopsy, the desired imaging modality should have a real-time guiding capability with high spatial and contrast resolutions for a deeply located lesion as well as no safety issues [5].…”

This paper investigates whether photoacoustic imaging (PAI) can provide the visualization of microcalcifications in breast tissue. For this, the geometrical correlation between the 3-D PA images of breast microcalcifications within ex vivo specimens and the corresponding mammograms was ascertained. Also, the optical absorbance of the calcification compositions (i.e., hydroxyapatite and calcium oxalate) was measured and compared with the PA responses of the microcalcifications. The experimental results demonstrated that the PA images discriminated between the microcalcifications and the surrounding tissue, and their locations in PA images reasonably meshed with those of the microcalcifications appeared in the mammograms. Also, the change in PA signal amplitude along the laser wavelength agreed with the absorbance of hydroxyapatite associated with the relatively high potential of malignant cancers, but not calcium oxalate with only benign cases.

“…A diagnosis of atypical ductal hyperplasia (ADH) in CNB results in an upgrade to ductal carcinoma in situ (DCIS) or invasive carcinoma during open surgery in up to 56% [15,[17][18][19]. DCIS, when diagnosed with CNB, is upgraded to invasive carcinoma during surgery in up to 50% [17,19,20]. Thus, regarding the higher accuracy of CNB in non-calcified lesions, the method is the standard diagnostic procedure in assessing masses and is commonly used under ultrasound guidance.…”
