| low-pass filter | A device or material with the opposite effect from a high-pass filter; most tissues act as low-pass filters of ultrasound signals. (05 Mar 2000) |

| high-pass filter | A device or material that allows high frequency signals to pass while attenuating other signals. (05 Mar 2000) |
| ventriculography, first-pass | Radionuclide ventriculography where a bolus of radionuclide is injected and data are recorded from one pass through the heart ventricle. Left and right ventricular function can be analyzed independently during this technique. First-pass ventriculography is preferred over gated blood pool imaging for assessing right ventricular function. (12 Dec 1998) |
| pass | 1. An opening, road, or track, available for passing; especially, one through or over some dangerous or otherwise impracticable barrier; a passageway; a defile; a ford; as, a mountain pass. ""Try not the pass!" the old man said." (Longfellow) 2. A thrust or push; an attempt to stab or strike an adversary. 3. A movement of the hand over or along anything; the manipulation of a mesmerist. 4. A single passage of a bar, rail, sheet, etc, between the rolls. 5. State of things; condition; predicament. "Have his daughters brought him to this pass." (Shak) "Matters have been brought to this pass." (South) 6. Permission or license to pass, or to go and come; a psssport; a ticket permitting free transit or admission; as, a railroad or theater pass; a military pass. "A ship sailing under the flag and pass of an enemy." (Kent) 7. A thrust; a sally of wit. 8. Estimation; character. "Common speech gives him a worthy pass." (Shak) 9. [Cf. Passus] A part; a division. Pass boat, a wooden or metallic box, used to carry cartridges from the service magazine to the piece. Pass check, a ticket of admission to a place of entertainment, or of readmission for one who goes away in expectation of returning. Origin: Cf. F. Pas (for sense 1), and passe, fr. Passer to pass. See Pass. Source: Websters Dictionary (01 Mar 1998) |
| absolute filter | <apparatus> A fine-pored, steam-sterilisable filter that is used to trap airborne microorganisms. The filter's pores are about 2 micrometres in diameter, smaller than the particles it is designed to remove. (06 May 1997) |
| bandpass filter | A device that allows a limited range of frequencies to pass. (05 Mar 2000) |
| Berkefeld filter | A bacterial filter used in 1891, made of earth known as Kieselguhr taken from the name of the mine in Hanover, Germany, from which the earth was found. Ground water at this mine had a clear blue colour suggesting the use of the earth as a filter. Origin: Berkefield, name of owner of the mine from which the material to make the filter was taken (05 Mar 2000) |
| bird's nest filter | A wire mesh vena cava filter. (05 Mar 2000) |
| bird's nest ivc filter | <radiology> Introduced 1982; Cook Inc., Bloomington, IN advantages, low profile: 14.5 Fr introducer sheath, low recurrent PE rates (1.1 - 2.7% by clinical history), low IVC thrombosis rates (2.9 - 5.0% by clinical history), placement in large diameter IVCs (not greater than40mm), free-form configuration does not require centreing in IVC disadvantages: stainless steel: ferromagnetic = magnetic susceptibility artifact, more operator dependent, difficult to place in short IVCs (need about 7cm for proper placement), prolapse of filter wires (? clinical significance) see also: indications (12 Dec 1998) |
| vena cava filter | A filter used for interruption of IVC to prevent pulmonary embolism; e.g., Greenfield filter. Synonym: venocaval filter. (05 Mar 2000) |
| vena-tech ivc filter | <radiology> Introduced as LGM (L.G. Medical, France), 1985; FDA aprroval 1991: Vena-Tech, Evanston, IL, 6-leg conical design with 6 stabilizing side bars, biocompatible metal known as Phynox (cobalt,chromium,iron,nickel,moly) Efficacy, recurrent PE: 2-6%, IVC occlusion: 8-24%, migration: 0-12% Advantages, ease of placement, excellent clot trapping efficiency, low profile, lacks ferromagnetic activity: minimal MRI artifacts Disadvantages, incomplete opening (6-19%): decreases clot-trapping efficiency, increased incidence from IJ approach, decreased with rapid deployment, increased IVC thrombosis rates: 8% initial reports; 22-24% on subsequent reports by ultrasound/MRI: 2-19% clinically symptomatic (12 Dec 1998) |
| venocaval filter | A filter used for interruption of IVC to prevent pulmonary embolism; e.g., Greenfield filter. Synonym: venocaval filter. (05 Mar 2000) |
| Rheinberg filter | <equipment> A colour-filter disk to be placed, as a dark field stop would be placed, below the substage condenser. The central circular area, that is filled with one of the two or three colour filters, should safely subtend the objective aperture. The annular quadrants around this are normally contrasting in colour. This is/are the colour shown by the organisms or other specimen detail against the coloured field. The effect is one kind of optical staining. (05 Aug 1998) |
| Greenfield filter | A multistrutted spring-styled filter usually placed in the inferior vena cava to prevent venous emboli from reaching the pulmonary circulation from the lower extremity. (05 Mar 2000) |
| micropore filter | A filter made of a meshwork of cellulose acetate or nitrate and with defined pore size. They can be autoclaved and the smaller pore sizes (0.22m,0.45m) are used for sterilising heat labile materials by filtering out micro organisms. Larger pore size filters are used in setting up Boyden chambers. They are about 150m thick and should be distinguished from Nucleopore filters. Millipore is a trade name for micropore filters.
