A computational model of the internal human pelvic environment. The model comprises meshed finite element regions corresponding to internal tissues or organs selected from the group consisting of pelvic muscles, vagina, vaginal walls, intestinal tissues, bowel tissues, bladder, bladder walls, cervix, and combinations thereof.
摘要:
A computational model of the human vaginal environment is disclosed. The model comprises finite element analysis software, segmented tissue regions, at least one defined material parameter for each of said segmented tissue regions, and at least one boundary condition for each of said segmented tissue regions. At least one of the boundary conditions is subject to physiological condition changes and the model comprises computing means for manipulating the material parameters and the boundary conditions with the finite element analysis software.

In a method for fabricating a hearing aid device, a hearing impaired person visits an audiologist at a dispenser location, and is examined to determine electronic settings for a hearing aid to correct the person's hearing impairment. At the same visit, an ear mold of the patient is obtained, which is scanned to produce a three-dimensional data set. A prototype is produced from the hearing aid data set, that does not contain any electronic components, and the prototype is test fitted with the patient. By interaction between the patient and the audiologist, the prototype is modified as needed, with each modification resulting in an updated three-dimensional data set being generated. When the prototype is acknowledged by the patient as being a comfortable fit, the three-dimensional data that were used to create the acceptable prototype are electronically transmitted to a fabrication site, at which the hearing device is manufactured therefrom. The hearing device is then sent to a location at which it is available to the patient.

A switch enables a telephone to use one virtual circuit to connect through a packet switched network to any number of other telephones. The switch supports multiple network types, permitting, for example, the conversion of UDP and AAL5 data to AAL2 data. Multiple switches, each connected to several other switches by ATM virtual circuits, are used to form a telephone network. Each telephone connects to just one switch. When a telephone call is made, the call is sent to the associated switch, which then determines, based on destination, to where the call should be routed. The call is sent through the telephone network to the destination switch, which in turn sends the call down the one virtual circuit to the destination telephone. Header stripping using out-of-band signaling minimizes bandwidth wastage by not requiring the ingress and egress points of the packet-switched network to maintain a synchronized connection state that must be regularly validated and updated with state and error information.

摘要:
A seed point is selected inside a structure that is to be segmented in image data. An adaptive model is defined around the seed point, and a preprocessing filter is applied only within the bounding region. A presegmentation of the preprocessed result is performed, and the bounding region is expanded if necessary to accommodate the presegmentation result. An adaptive model for post-processing may be used. The model is translated, rotated and scaled to find a best fit with the pre-segmented data. Additional models can be grown based on testing performed on points on a perimeter of previous models to improve the segmentation of an object.
摘要:
A polymeric, surgical clip having first and second curved legs with each having a pair of opposing side surfaces joined at their proximal ends by a flexible hinge section and movable from an open position to a closed position for clamping a vessel between curved opposing inner surfaces. The first leg terminates at its distal end in a female locking member, and the second leg member terminates in a male locking member complimentary to the female locking member such that when the first and second leg members are moved from an open position to a closed position about the hinge section the male member is lockingly engaged in the female locking member. The clip has a détente positioned on the outer surface of the first leg between the hinge section and the female locking member which serves to urge the first leg to straighten during closure of the clip to reduce the force required to close the surgical clip.
摘要:
A system and method for utilizing a Digital Imaging and Communications in Medicine (DICOM) structured report (SR) for workflow optimization are provided. A method for providing a DICOM SR in an extensible markup language (XML) comprises: generating the DICOM SR; mapping attribute fields of the DICOM SR to an XML document; defining the XML document as a DICOM SR binary object; and storing the XML document in the DICOM SR.
