An instrument-holding projection imaging vector guide and method of use is provided herein. In one embodiment of the present invention, a instrument-holding projection imaging vector guide is provided comprising a radio-opaque skin entry point member, a frame member and a diaphragm. The radio-opaque skin entry member is used to determine a skin entry point. The diaphragm is used to determine a diaphragm entry point. The radio-opaque skin entry point member and the diaphragm together determine the vector along which an appropriate medical instrument is to follow in order to contact a target inside a patient's body.

The present invention includes a stereotactic system and a method of use for determining vectors involving no electronic components. The stereotactic system comprises a lower plane device and an upper plane device, each having a pair of non-parallel image-conspicuous lines. The system can be used with magnetic resonance imagining (MRI), computed tomography (CT), plain film, radioscopy or fluoroscopy. The relationship of the lines enables a medical practitioner to accurately, directly, and easily determine the vector along which a medical device should be advanced to reach a target within the patients body using a minimized number of images. As an option, the system may include an additional disposable lower plane device having a pair of non-parallel image-conspicuous lines adapted to determine a skin entry point on the patient for the medical device.

Apparatus is disclosed for assisting in the location, vectoring, and insertion of a needle-like medical device relative to a patient's body using medical imaging equipment that produces patient cross-sectional images and that has a monitor which displays produced cross-section images. Included image-conspicuous, double-V reference patterns are sectioned and displayed at the equipment monitor in a manner readily identifying and quantifying position changes necessary to assure accurate needle-device location, vectoring, and insertion.

Apparatus for assisting in the manual location, vectoring, and insertion of a medical instrument relative to a patient's body using medical imaging equipment providing a cross-sectional imaging plane and a monitor which displays a distance calibrated cross-section imaged at the equipment imaging plane of the patient and an apparatus reference pattern. The displayed image sets forth the actual distance and angular orientation between the image plane and a reference axis of the device pattern to physically define a point on the pattern that corresponds to a point on the image.
