A method and device for marking a patient's skin during an ultrasound examination to denote a feature of interest. The device comprises a first portion and a second portion. The first portion is adapted for attachement of the device to an ultrasound transducer. The second portion is adapted for marking the skin of the patient to denote the feature of interest. The first and second portions are rotatably attached to each other. During an ultrasound examination of the patient to locate the feature of interest, the second portion is rotated so that it is spaced away from the patient's skin. The ultrasound examination is conducted in the normal manner until the feature of interest is located, at which time the second portion is rotated so that it contacts and marks the patient's skin to denote the feature of interest.

1. An ultrasound accessory for marking a patient's skin comprising:(a) a first element adapted to be attached to an ultrasound transducer;(b) a second element adapted for rotation with respect to said first element, said 5 second element contacting a surface subject to ultrasound examination, wherein at least one of said first element and said second element are comprised of an ultrasound permeable material, and wherein at least one of said first element and said second element are rotatably attached by a hinge;(c) a marking element capable of marking a patient's skin with ink, paint, crayon or grease, said marking element attached to said second element, said marking element comprising a substantially perpendicularly-centered projection on said second element of said ultrasound accessory; and(d) a means for aligning said ultrasound accessory to assure a mark made by said marking element corresponds to an ultrasound image produced by said transducer. 2. The ultrasound accessory of claim 1, wherein said first element is comprised of ultrasound permeable material and said marking element is adapted to apply ink to the patient's skin when the patient's skin is covered with an ultrasound transmission gel. 3. The ultrasound accessory of claim 1, wherein at least one of said first element and said second element are rotatably attached by at least one spherical protrusion on said second element and snap-fit into at least one indentation on said first element. 4. The ultrasound accessory of claim 1, further comprising a means for aligning said ultrasound accessory to assure a mark made by said second element corresponds to an ultrasound image produced by said transducer. 5. The ultrasound accessory of claim 4, wherein said aligning means comprises a spatial ruler sticker indicating the center of the transducer when said second element is rotated to contact a surface subject to ultrasound examination. 6. The ultrasound accessory of claim 1, wherein said first element comprises a means for removable attachment to said ultrasound transducer. 7. The ultrasound accessory of claim 6, wherein said removable attachment means is selected from the group consisting of an adhesive sticker, hook and loop structure, a snap connector and a slide connector. 8. The ultrasound accessory of claim 1, wherein said first element comprises means for integrating with an attachment means present on said ultrasound transducer. 9. The ultrasound accessory of claim 8, wherein said integrating means comprises a counterpart to a coupling means present on said ultrasound transducer selected from the group consisting of a snap connector, a slide connector and a lock-joint. 10. The ultrasound accessory of claim 1, wherein said marking element makes an indentation in said surface subject to ultrasound examination. 11. The ultrasound accessory of claim 10, wherein said marking element comprises a hollow cylinder operatively associated with said second element of said ultrasound accessory, said marking element being mounted to a long side of said transducer. 12. The ultrasound accessory of claim 1, wherein said marking element is integral with said second element of said ultrasound accessory. 13. The ultrasound accessory of claim 1, wherein said device is made of disposable plastic. 14. The ultrasound accessory of claim 1, wherein said second element comprises a finger tab for controlling rotation of said second element relative to said first element. 15. The ultrasound accessory of claim 1, wherein said second element comprises a spring-loaded mechanism for rotation of said second element relative to said first element. 16. The ultrasound accessory of claim 1, wherein said marking element comprises a marking device having a singer portion/marking leaf. 17. The ultrasound accessory of claim 16, wherein said marking device is a retractable ink stamp. 18. The ultrasound accessory of claim 16, wherein said marking device is a pre-inked applicator mechanism. 19. The ultras ound accessory of claim 1, further comprising a ruler sticker attached to either of said first element or said second element. 20. The ultrasound accessory of claim 1, wherein said patient is a human patient. 21. A method of marking a patient's skin at a feature of interest during an ultrasound examination comprising:(a) locating a feature of interest by conducting an ultrasound examination of a patient using an ultrasound device, said device comprising an ultrasound transparent ultrasound accessory having a first element rotatably attached to a second element, a marking element capable of marking a patient's skin at a point directly beneath an ultrasound transducer attached to said second element, said first element being adapted for attachment to said ultrasound transducer and said second element being rotatable into contact said patient;(b) rotating said second element of said ultrasound accessory to contact said patient's skin with said marking element; and,(c) marking said patient's skin to denote a feature of interest. 22. The method of claim 21, wherein said ultrasound examination is an application selected from the group consisting of vein mapping prior to harvest, perforator vein marking prior to surgical ligation; locating lesser saphenous origin prior to surgical ligation; locating valves prior to valvuloplasty or transposition; denoting a proximal end of deep venous thromboses to monitor for propagation on follow up studies; denoting thrombus ength for investigational purposes to determine propagation patterns for various low molecular weight heparins; marking a subclavian or femoral vein for catheterization procedures, and denoting a venous malformation prior to percutaneous ablation. 23. The method of claim 21, wherein said ultrasound examination is an application selected from the group consisting of: marking the length of occlusion or site of arterial graft stenosis prior to focal surgical revision or prior to insertion of a stent or endostent; marking patent target artery prior to bypass; marking a fistula prior to focal surgical revision; marking for ultrasound-guided pseudoaneurysm repair by manual compression or thrombin injection; marking a small pseudoaneurysms for surgical repair; denoting Vasoseal™ migration; marking carotid bifurcation prior to endartectomy surgery; and marking an optimal transcranial doppler window. 24. The method of claim 21, wherein said ultrasound examination is an application selected from the group consisting of: marking a breast lesion prior to needle biopsy; marking breast implant leaks; marking a thyroid abnormality prior to needle guided biopsy; marking a tissue or cyst prior to biopsy, denoting fluid prior to aspiration; marking amniotic pocket prior to amniocentesis; marking a hernia prior to repair; denoting an extremity pathology; denoting a foreign object; marking for pericardiocentesis; marking for renal pelvis aspiration; and ultrasound contrast applications. 25. The method of claim 21, wherein said ultrasound examination is a veterinary ultrasound application selected from the group consisting of: initial diagnostic ultrasound; marking for liver aspiration, mass aspiration, cystocytesis, lung pathology; biopsies; denoting organ or tissue abnormalities; and assessing cysts and tumor sizes. 26. An ultrasound accessory for marking a patient's skin comprising, a marking element for marking a patient's skin attached to a body element adapted to be attached directly between an ultrasound transducer and a patient's skin, said transducer having a scanning face and said marking element adapted to mark the patient's skin with ink directly beneath said scanning face.
