Repairs of cartilage defects or of cartilage/bone defects in human or animal joints with the help of devices including a bone part (1), a cartilage layer (2) and a subchondral bone plate (4) or an imitation of such a plate in the transition region between the cartilage layer (2) and the bone part (1). After implantation, the bone part (4) is resorbed and is replaced by reparative tissue only after being essentially totally resorbed. In a critical phase of the healing process, a mechanically inferior cyst is located in the place of the implanted bone part (1). In order to prevent the cartilage layer (2) from sinking into the cyst space during this critical phase of the healing process the device has a top part (11) and a bottom part (12), wherein the top part (11) consists essentially of the cartilage layer (2) and the subchondral bone plate (4) and the bottom part (12) corresponds essentially to the bone part (1) and wherein the top part (11) parallel to the subchondral bone plate (4) has a larger diameter than the bottom part (12). After implantation in a suitable opening or bore (20), the cartilage layer (2) and the subchondral bone plate (4) are supported not only on the bone part (1) but also on native bone tissue having a loading capacity not changing during the healing process. Therefore, the implanted cartilage layer cannot sink during the healing process.

The present invention relates to an apparatus, method, software algorithm and system for evaluating plants for conditions or characteristics. In one aspect, the method can include imaging at least a portion of the plant and evaluating the image for discriminating condition(s) or characteristic(s) of interest. In one example, soybean roots are imaged and the image is evaluated to discriminate between soybean cyst nematode (SCN) cysts and the plant roots to count the number of SCN cysts for the plant. In another embodiment, a plant is illuminated by a ultra-violet radiation selected to cause photo-induced fluorescence of a target, e.g. SCN cysts. The fluorescence emitted is collected and analyzed to discriminate between the target and the remainder of the plant.

The invention discloses an artificial lens with an iris diaphragm, comprising an optical zone (1) which is transparent at the center, the iris diaphragm (2) surrounding the optical zone (1) and a loop (3); the artificial lens is in an integrated style and is composed of an entire block of material, the material is selected from foldable materials such as hydrophobic acrylic ester, hydrophilic acrylic ester, silica gel, etc. The artificial lens with the iris diaphragm of the invention has soft texture, can be filled or implanted in the eyes by a small incision after being folded; in addition, the artificial lens has high refractive index, thin lens, small incision and slow formation of after cataract and can slowly restore in 2-30 seconds after being implanted, thus cyst membrane is not easy to be damaged; moreover, the artificial lens has the advantages of little astigmia developed in post-operation, quick healing, fast recovery of visual performance and little postoperative treatment; a brown iris, which is the natural color iris of Chinese, can be adopted, and the eye implanted with such an artificial lens looks more natural.

A system and method for generating a three-dimensional visualization image of an object such as an organ using volume visualization techniques and exploring the image using a guided navigation system which allows the operator to travel along a flight path and to adjust the view to a particular portion of the image of interest in order, for example, to identify polyps, cysts or other abnormal features in the visualized organ. An electronic biopsy can also be performed on an identified growth or mass in the visualized object. Virtual colonoscopy can be enhanced by electronically removing residual stool, fluid and non-colonic tissue from the image of the colon, by employing bowel preparation followed by image segmentation operations. Methods are also employed for virtually expanding regions of colon collapse using image segmentation results.

A fenestration system can be useful for draining cysts, abscesses, or other bodily cavities. A fenestration system can include: a drainage screwdriver; a drainage screw removably receivable onto the drainage screwdriver; and a drainage cap removably coupleable with the drainage screw when the drainage screw removed from the drainage screwdriver. The drainage screwdriver can receive the drainage screw so that the drainage screw can be screwed through tissue and/or cyst or abscess sac. The drainage screwdriver can then release the drainage screw so that it is inserted into the tissue, cyst, or abscess so as to be capable of drainage. A lumen in the drainage screw can function similarly to a drainage tube. The drainage cap can be applied to the drainage screw to close the lumen to inhibit other fluids or particles from entering into the tissue, cyst, or abscess via the lumen.

A system and method are provided for generating a three-dimensional visualization image of an object such as an organ using volume visualization techniques and exploring the image using a guided navigation system that allows the operator to travel along a flight path and to adjust the view to a particular portion of the image of interest in order, for example, to identify polyps, cysts or other abnormal features in the visualized organ; where imaging data sets are acquired using conventional two-dimensional scans of the object in both a supine and prone orientation, and correspondence between the respective data sets is determined to permit jumping from one visualization orientation to the other while remaining at the same virtual location within the organ.

A method is provided for treating pain in patients recovering from post-surgical trauma by administering between about 13 to about 30 mg of diclofenac potassium in a liquid dispersible formulation over a period of at least 24 hours, wherein the daily total amount of diclofenac potassium administered is less than or equal to about 100 mg. The method is particularly useful in treating acute pain in bunionectomy patients.

A quantification method and an imaging method are disclosed, capable of quantifying the margin feature, the cysts feature, the calcifications feature, the echoic feature and the heterogenesis feature of a tumor, and capable of imaging the margin feature, the cysts feature, the calcifications feature and the heterogenesis feature of a tumor. The quantification method and the imaging method calculate the moving variance of the gray scale of each of the pixel points based on the gradient value of the gray scale of these pixel points. Then, depending on the purpose of the quantification method or the imaging method, the maximum value, the minimum value, the mean value, and the standard deviation of the moving variance of the gray scale of these pixel points are calculated, respectively. At final, with the definition of the threshold value and the imaging rule, the above features of the tumor are quantified or imaged.

In NMR/MRI imaging, a location is noted for a point in the imaged space, and referred to a reference location so that the point in imaged space is known thereafter, without the need to locate the point again in further imaging steps. For breast cancer diagnosis and biopsy, a breast holding fixture immobilizes the breast. A volumetric image is taken encompassing a portion of the breast. In the same or a subsequent image, a fiducial mark is detected to determine the position of a holder for a biopsy tool or other modality. The tissue feature can be a tumor, cyst or tubal lesion, made temporarily visible in the image by perfusion with a contrast agent. After the contrast agent dissipates, the location of the tissue feature can still be determined by reference to the position of the fiducial marker, which is optional adjustable by post-imaging metered displacement.

A haptic sensor for performing palpation includes a deformable membrane having a reflective surface, a light source, a camera, and a processor. When the sensor is pressed against an object on a body, the deformable membrane deforms to contour to the shape of the object, light is reflected off the reflective surface, and captured by a camera. The reflected light is processed to reconstruct a 3-D image of the object. The rendered image can show abnormalities such as cysts, tumors, or other abnormalities, as well as arterial pressure pulses. In different embodiments, the sensor illuminates the deformed membrane from multiple directions, using shape-from-shading or grayscale mapping, or using video streams to provide more accurate images. The sensor is able to be included as part of a mobile device, such as a mobile phone, thereby making it compact and portable.
