The feasibility of spatial frequency domain imaging (SFDI) for breast surgical margin assessment was evaluated in tissue-simulating phantoms and in fully intact lumpectomy specimens at the time of surgery. Phantom data was evaluated according to contrast-detail resolution, quantitative accuracy and model-data goodness of fit, where optical parameters were estimated by minimizing the residual su...

Monitoring and controlling respiratory motion is a challenge for the accuracy and safety of therapeutic irradiation of thoracic tumors. Various commercial systems based on the monitoring of internal or external surrogates have been developed but remain costly. In this article we describe and validate Madibreast, an in-house-made respiratory monitoring and processing device based on optical trac...

AbstractIntroduction Silicone gel breast implants are used for breast reconstruction post mastectomy. In the event of cancer recurrence, the radiation oncologists are forced to irradiate through the prosthesis device. Due to prosthesis higher atomic number dose perturbations occur during treatment. This study determined the influence of silicone gel thickness on the photon beam distribution. Ma...

Scherer et al.1 claim that the phantom study in our Article2 might not reliably model real microcalcifications in human breast and referred to previous publications3–5 to emphasize that the scattering signal depends on particle grain sizes. Specifically, they mention Michel et al.’s simulation results6, which report a larger scattering signal of calcium hydroxyapatite compared with calcium oxal...

This white paper summarizes a study comparing MicroDose Diagnostic Scan to geometric magnification for imaging fine image details, and explains the efficiency of the Diagnostic Scan functionality of the MicroDose system based on two phantom studies. Highlights of these studies reveal: • Diagnostic Scan, an exclusive feature of Philips MicroDose Mammography, helps discern fine details in spot co...

EPIDEMIOLOGY OF CHRONIC PAIN AFTER SURGERY The incidence of CPSP varies significantly by site of surgical procedure (Table 35-1); however, most reports support an incidence of at least 10% of patients having pain 1 year after surgery. Several high-quality reviews since the 1990s have highlighted the problem of chronic pain after sur...
