A system and method for using pre-procedural images for registration for image-guided therapy (IGT), also referred to as image-guided intervention (IGI), in percutaneous surgical application. Pseudo-features and patient abdomen and organ surfaces are used for registration and to establish the relationship needed for guidance. Three-dimensional visualizations of the vasculature, tumor(s), and organs may be generated for enhanced guidance information. The invention facilitates extensive pre-procedural planning, thereby significantly reducing procedural times. It also minimizes the patient exposure to radiation.

A device for creating a channel between the stomach lumen and the abdominal surface of a patient. The device includes a tube and a first bolster. The tube has a proximal end, a distal end, and a wall, the wall having an inner surface and an outer surface, and each end having an opening therein. The first bolster is attached to the distal end of the tube and the tube is adapted to slidably receive a feeding device having a shaft, wherein at least a portion of the outer diameter of the shaft of the feeding device is substantially the same size as that of the inner wall of the tube. The first bolster is adapted to sealingly engage with the patient so as to minimize or avoid fluid leakage about the tube. The present invention is also directed to a method of using an artificial stoma.

The present invention provides a system for enabling the sensing of changes in pressure in response to uterine muscle tone changes relating to contractions, and for enabling the evaluation of contractions based thereon. The system enables a portion thereof to effectively and efficiently project at least partially below the non-compressed abdominal surface, and provides electrical isolation of the system elements. It enables ease of use and enhanced patient comfort. It also enables maximized sensitivity and minimized system loading retention pressure.

Provided are a remote fetal monitoring method and system. The remote fetal monitoring method comprises the following steps that pregnant woman abdominal surface image data are acquired and transmitted to a central station; the central station receives the image data and performs centralized processing on a plurality of pregnant woman abdominal surface image data and sends marked data of one or more positions guiding an operator to place a fetal monitoring detection probe to a remote fetal monitor; the fetal monitor places the fetal monitoring detection probe according to marked position points to obtain fetal monitoring signals and screens out a best-quality fetal monitoring signal and the fetal monitoring detection probe placement position point corresponding to the signal; the fetal monitoring detection probe is placed on the position point to perform continuous fetal monitoring. The remote fetal monitoring method and system conducts intelligent placement guidance on the fetal monitoring detection probe, the accuracy of the fetal monitoring detection probe placement position is greatly improved, accordingly a high-quality fetal monitoring signal can be obtained, the monitoring quality of the remote fetal monitoring system is improved, and the operating efficiency of the system is improved.

A non-invasive method and apparatus for monitoring the bladder volume in humans or animals. The monitoring measurements are based on the analysis of ultrasound signals from at least two individual ultrasound transducer arrays. Each one individual ultrasound transducer array has a contact face, which is arranged in order to transmit an ultrasonic signal through an abdominal surface of an individual being monitored. The method and apparatus includes the arranging of each individual transducer array on the abdominal surface around an axis which extends from a point on the abdominal surface through a point on or within the urinary bladder. The method and apparatus further comprises that each individual transducer array is arranged to scan the bladder using a two-dimensional scan plane which extends radially from the transducer array through the bladder.

The invention relates to a phase-staggered super-resolution method for respiratory motion signals on the surface of the chest and abdomen, which belongs to the technical field of precision instruments and thoracoabdominal radiotherapy; the method first converts the respiratory motion signal into a periodic signal through a signal conversion module, and then through a phase difference multi-output module , forming three outputs with equal phase difference with a phase difference of π / 2, and then forming five outputs with equal phase difference with a phase difference of π / 5 through the resistance chain multiphase generating module, and then forming a square wave through a multiphase sine square wave conversion module, And through the multi-phase fusion logic gate module to form the out-of-phase super-resolution square wave output, that is, to realize the transformation of one cycle of respiratory motion signal into a multi-cycle out-of-phase square wave signal, and the phase error phase super-resolution square wave output signal quarter cycle of .

The invention discloses an image guided registration system for abdominal surgery interventional operation, and a related device. An image guided registration method for the abdominal surgery interventional operation comprises the steps that firstly, the registration result of a physical space and a preoperative image space is obtained; then abdominal characteristic point sets corresponding to abdominal surface images when a patient is in different respiration states are obtained, a depth camera is utilized to conduct corresponding processing on the abdominal surface images and preoperative abdominal surface images, and thus multiple intraoperative characteristic point sets and multiple preoperative abdominal characteristic point sets are obtained; and finally, according to the registration result of the physical space and the preoperative image space, a reference system of the intraoperative characteristic point sets is transformed into an intraoperative image space, in the intraoperative image space, deformable registration is conducted on the intraoperative characteristic point sets and the multiple abdominal characteristic point sets, thus the purpose of real-time registrationof the intraoperative image space of the patient in the different respiration states and the physical space is achieved during operation, and the precision of image registration in the abdominal surgery interventional operation process is improved.
