Medical emitter/detector imaging/alignment system and method

Номер: US20120022357A1
Автор: Alan Fischer, Andrew G. Fischer, David Chang, Nicholas Ransom Powley
Принадлежит: Individual

Improved methods and apparatuses for imaging during medical procedures in accordance with various embodiments of the present invention include use of an image correction algorithm. In various embodiments, an original image of a region of interest where a medical procedure occurring along a particular axis will be performed is created with a beam emitter and a generally planar detector. Due to the emitter not being aligned orthogonal to the detector, the original image will be skewed. Using a known location and orientation of the detector, a location and orientation of the emitter provided by a position monitoring system, and the original image, a processing system can execute the image correction algorithm to provide a corrected image to allow a surgeon to perform the medical procedure while viewing an accurate corrected image in real-time.

In an X-ray imaging system, an X-ray source has a lightweight and small-sized X-ray tube. The X-ray tube is a fixed anode X-ray tube without having a target rotating mechanism. The X-ray tube uses a cold cathode electron source, which does not need a filament and a heater. An image acquisition control device moves the X-ray source to each of plural positions predetermined on a cross bar of a holder by control of a drive source of a shift mechanism. Whenever the X-ray source reaches each position, the X-ray source emits X-rays to an object, and a cassette detects the X-rays transmitted through the object to take an image. Based on data of taken plural images, tomographic image, which puts emphasis on a region of interest inside the object, is produced.

Vascular roadmapping

Номер: US20120183189A1
Автор: Pierre Lelong, Raoul Florent
Принадлежит: KONINKLIJKE PHILIPS ELECTRONICS NV

Cardiac roadmapping consists in correctly overlaying a vessel map sequence derived from an angiogram acquisition onto a fluoroscopy sequence used during PTCA intervention. This enhanced fluoroscopy sequence however suffers from several drawbacks such as breathing motion, high noise level, and most of all suboptimal contrast-enhanced mask due to segmentation defaults. This invention proposes to reverse the process and to locally overlay the intervention device as seen in fluoroscopy onto an optimal contrast-enhanced image of a corresponding cycle. This drastically reduces or suppresses the breathing motion, it provides the high image quality standard of angiograms, and avoids segmentation defaults. This proposal could lead to a brand new navigation practice in PCI procedures.

Depth disambiguation of interventional instruments from a single x-ray projection image and its calibration

Номер: US20120190972A1
Автор: Nicolas Pierre Bruno Gogin, Pascal Cathier, Raoul Florent
Принадлежит: KONINKLIJKE PHILIPS ELECTRONICS NV

X-ray images are projective, meaning that the 3D geometry is flattened along projection lines going from the source to the detector. In particular procedures, such as mapping or ablation, the interventional instrument lies on the wall of the organ. Using a 3D segmentation of this organ registered to the x-ray, the instrument necessarily lies on the intersection of this surface with its projection line. The line and the surface typically intersect with a segmentation surface at a discrete number of points (typically 2 for shapes such as the anterior of the LA). One then has just to disambiguate between these different possible locations to determine the exact location of the instrument. In this invention, we propose to use the apparent width of the instrument measured in x-ray images to accomplish this task.

Surgical bolts are useful for solid visceral wound hemostasis. The devices utilize flexible, variable depth transfixing bolts that penetrate the viscera. These bolts bring the tissue into apposition and hold said tissue in apposition while the wound heals. These bolts, or soft tissue rivets, overcome the limitations of sutures that are currently used for the same purposes. The devices are flexible, bendable, and conformable in their wet or dry state. The bolts include pressure plates that are capable of exerting compressive pressure over broad areas of visceral wounds without causing tearing of the friable parenchyma. The bolts are placed and removed by open surgery or laparoscopic access. The bolts can be placed into tissue where both sides of the bolt are exposed, or they can be placed blindly into tissue where the bolt does not protrude out of the tissue at its distal end.

When a multi-system setting command switch, targeted rotating position information switches, and a command executing switch are pressed down, a CPU reads out a path of frontal and lateral systems from a current position to a setting position from a setting position information memory, and reads out rotation direction and angle from a targeted position information memory. The CPU moves the frontal and lateral systems horizontally along the read-out path until the commanded setting position information conforms to detected actual position information. When the setting position information conforms to the actual position information, the frontal and lateral systems are rotated successively until the commanded rotation direction and angle conform to the detected actual position information. Thereby a fluoroscopic X-ray system can be moved smoothly from a standby position via the setting position to a targeted rotating position.

Implantable in vivo sensors used to monitor physical, chemical or electrical parameters within a body. The in vivo sensors are integral with an implantable medical device and are responsive to externally or internally applied energy. Upon application of energy, the sensors undergo a phase change in at least part of the material of the device which is then detected external to the body by conventional techniques such as radiography, ultrasound imaging, magnetic resonance imaging, radio frequency imaging or the like. The in vivo sensors of the present invention may be employed to provide volumetric measurements, flow rate measurements, pressure measurements, electrical measurements, biochemical measurements, temperature, measurements, or measure the degree and type of deposits within the lumen of an endoluminal implant, such as a stent or other type of endoluminal conduit. The in vivo sensors may also be used therapeutically to modulate mechanical and/or physical properties of the endoluminal implant in response to the sensed or monitored parameter.

The present relates to a method and system for determining the position and orientation of implants located in a body part of a patient. The method and system comprise determining voxels having an intensity value corresponding to implants in a three-dimensional radiographic representation of the body part. The method and system further comprise generating multiple random virtual implants, providing a score for each virtual implant, until obtaining a score that identifies implants. The score is based on a number of voxels having an intensity value corresponding to implants contained in each generated virtual implant. And the method and system comprise determining, based on the score of virtual implants, the position and orientation of the implants located in the body part. 1.
