Embodiment Construction

[0030] Figure 1A An exemplary breathing resistance device 10 is shown in . The device has a body 11 made of a resilient material (e.g., or stainless steel or other similar material). The body provides the cover and base for the single use mouthpiece 12 . The mouthpiece and body are connected to each other by a simple form of fitting so that the mouthpiece can be easily attached to and removed from the body by a direct insertion and withdrawal action; preferably, no twisting or use of tools is involved. Any similar form or connection method may be applicable.

[0031] The mouthpiece 12 has substantially a tubular, hollow shape, with a proximal opening 121 adapted to be inserted into a patient's mouth, and a distal opening 122 providing a flow connection into the main body 11 .

[0032] However, it should be appreciated that the material, size and shape of the body 11 and mouthpiece can vary widely while still maintaining the function of providing resistance against free br...

Abstract

A method of and device for acquiring in-vivo images or quantitative / qualitative data (perfusion, blood flow, vascularization, contrast enhancement, selective blood supply management) of interior parts of the human body (20) is described, using an imaging system (21) and including the steps of positioning the body (20) relatively to the imaging system (21), applying a respiratory resistance device (10) to the respiratory system of the body (20), and performing an image acquisition step during or concomitantly an inhalation / inspiration / suction or exhalation / Valsalva / expiration phase, during which the body provides suction or exhalation against a resistance as provided by the respiratory resistance device (10).

Description

technical field [0001] The present invention relates to blood flow control systems, devices and methods, in particular to imaging systems for the human body, such as X-ray and related tomographic imaging systems. Background technique [0002] Images of the inside of the human body are well-established tools for providing graphical information in the form of pictures, printed photographs, and screen displays for subsequent interpretation by the skilled person. [0003] Detection of blood flow related states is an important part of such images for many purposes. In order to improve the detection of blood flow conditions, it is known that the injection of a contrast agent into the blood stream can increase the information. [0004] A well-known example of such a method is computed tomography (CT) angiography, which is generally accepted as an investigation for patients suspected of having pulmonary embolism and other vascular and parenchymal lesions. The advantages of CT are ...
