  • Patent number: 9856454
    Abstract: A method for rapid mincing of adipose tissues to isolate live cells in vitro is disclosed to overcome the drawbacks of a lead procedure of isolating live cells by holding a knife to mince adipose tissues, which can only isolate a small number of live cells and obtain low cell viability. The method includes: providing an adipose tissue; mincing the adipose tissue homogeneously by a mincing device; adding a reagent into the minced adipose tissue to perform hydrolysis; performing centrifuge and isolation; and removing a supernatant to obtain a cell pellet. Therefore, the time of mincing adipose tissues can be shortened, and contaminations caused by repeated use of the knife can be avoided. The method can be used for isolating live cells of adipose tissues to improve the number of live cells per unit weight of adipose tissues without reducing the cell viability.

  • Publication number: 20170337732
    Abstract: For human body representation, bone length or other size characteristic that varies within the population is incorporated into the geometric model of the skeleton. The geometric model may be normalized for shape or tissue modeling, allowing modeling of the shape without dedicating aspects of the data-driven shape model to the length or other size characteristic. Given the same number or extent of components of the data-driven shape model, greater or finer details of the shape may be modeled since components are not committed to the size characteristic.

  • Publication number: 20170249423
    Abstract: In scan data retrieval, a mesh is fit (32) to surface data of a current patient, such as data from an optical or depth sensor (18). Meshes are also fit (48) to medical scan data, such as fitting (48) to skin surface segments of computed tomography data. The meshes or parameters derived from the meshes may be more efficiently compared (34) to identify (36) a previous patient with similar body shape and/or size. The scan configuration (38) for that patient, or that patient as altered to account for differences from the current patient, is used. In some embodiments, the parameter vector used for searching (34) includes principle component analysis coefficients. In further embodiments, the principle component analysis coefficients may be projected to a more discriminative space using metric learning.

  • Patent number: 9665936
    Abstract: A computer-implemented method for providing a see-through visualization of a patient includes receiving an image dataset representative of anatomical features of the patient acquired using a medical image scanner and acquiring a body surface model of the patient using an RGB-D sensor. The body surface model is aligned with the image dataset in a canonical/common coordinate system to yield an aligned body surface model. A relative pose of a mobile device is determined with respect to the RGB-D sensor and a pose dependent visualization of the patient is created by rendering the image dataset at a viewpoint corresponding to the relative pose of the mobile device. Then, the pose dependent visualization of the patient may be presented on the mobile device.
