Abstract: System, apparatus, and method for automatic detection of arthritis according to temperature asymmetry estimation in contralateral joints is presented. Simultaneously recorded thermogram and the optical image of an inspected joint and its contralateral joint are sent to the processing unit, where they are stored, processed, and analyzed.

Grid of points of interest is distributed inside the inspected and the contralateral joint's outline. Temperature maps are calculated according to both grids points and the temperature disparity map is estimated. The set of inflammation regions is obtained by analyzing the temperature disparity map and collecting adjacent points containing temperature differences surpassing the threshold. The system, apparatus, and method are non-invasive and non-contact, and suitable for real world environments with natural home or health care institutions background.

Abstract: The present disclosure discloses a method and an apparatus for acquiring motion information. A frequency domain transformation is performed on a detection signal of a vibration propagating in a medium to obtain a frequency domain signal, then a signal that is outside of a defined vibration velocity range is removed from the frequency domain signal, that is, only a vibration signal is retained, and then a position-time diagram is obtained along a defined vibration propagation direction. It is not necessary to perform motion estimation on propagation of the vibration by a complicated calculation, and it is only necessary to determine the presence or absence of the vibration by processing in the frequency domain, and then the position-time diagram is obtained, which is a highly efficient method for acquiring motion information.

One or more template grids can have a plurality of apertures extending therethrough to receive and guide a biopsy needle along a trajectory associated with respective apertures when the template grid is fixed to the support and the biopsy system is positioned in the perineal area of a patient. Patient-specific template grids can also be developed and produced. This system enables fully transperineal prostate biopsy (i.e. both imaging and needle placement are perineal) and eliminates the need for an external racking device for image fusion as well as needle tracking. In addition, it reduces the infection risk associated to transrectal approach.

Abstract: A computer-controlled system determines attributes of a frexel, an area of human skin, and applies a modifying agent (RMA) at the pixel level, typically to make the skin appear more youthful and so more attractive. The system scans the frexel, identifies unattractive attributes, and applies the RMA, typically with an inkjet printer. The identified attributes relate to reflectance and may refer to features such as irregular-looking light and dark spots, age-spots, scars, and bruises. Identified attributes may also relate to the surface topology of the skin, for more precisely enhancing surface irregularities such as bumps and wrinkles. Feature mapping may be used, for example to make cheeks appear pinker and cheekbones more prominent. The RMA can be applied in agreement with identified patterns, such as adding red to a red frexel, or in opposition, such as adding green or blue to a red frexel, according to idealized models of attractiveness.

The caliper device is positioned around the region of body tissue within the primary plane fixation instrumentation. The caliper arms (and optionally, the center plate fixator) move together to “thicken” the region of tissue between them. The device is preferably constructed of radiotransparent material and for single-use applications.

Abstract: An ultrasound signal processing device includes a transmitter that causes transducers to transmit an ultrasound beam, a receiver that, based on reflected waves received by reception transducers, generates reception signal sequences corresponding to the reception transducers, and a delay-and-sum section that, for a reference observation point in a region of interest, calculates delay times of reflected wave arrival to each of the reception transducers from the reference observation point as reference delay times and generates acoustic line signals by using the reference delay times corresponding to the reception transducers. For one or more dependent observation points in the region of interest that are contiguous in a depth direction from the reference observation point, the delay-and-sum section generates acoustic line signals by applying the reference delay times corresponding to the reception transducers.

Abstract: An intraoperative imaging system combines a gamma probe and an ultrasound probe. The probes are linked to provide co-registration of gamma radiation detected by the gamma probe with an image acquired by the ultrasound probe. The gamma probe has a converging collimator made of a metal block having a plurality of channels therein, which converge from an output face toward an input face. Each channel extends between and opens out at the faces such that openings at the input face have smaller cross-sectional areas than openings at the output face so that each channel tapers inwardly from the output face to the input face. The collimator has an external focal point distant from the input face. The system improves identification and localization of cancerous cells, facilitating more accurate biopsy data and more complete surgical resection. The gamma probe increases sensitivity, while maintaining spatial resolution, and increasing depth of view.
