OsiriX 3.3.2

OsiriX is an image processing software dedicated to DICOM images (".dcm" / ".DCM" extension) produced by medical equipment (MRI, CT, PET, PET-CT, ...) and confocal microscopy (LSM and BioRAD-PIC format). It can also read many other file formats: TIFF (8,16, 32 bits), JPEG, PDF, AVI, MPEG and Quicktime. It is fully compliant with the DICOM standard for image comunication and image file formats. OsiriX is able to receive images transferred by DICOM communication protocol from any PACS or medical imaging modality (STORE SCP - Service Class Provider, STORE SCU - Service Class User, and Query/Retrieve).

OsiriX has been specifically designed for navigation and visualization of multimodality and multidimensional images: 2D Viewer, 3D Viewer, 4D Viewer (3D series with temporal dimension, for example: Cardiac-CT) and 5D Viewer (3D series with temporal and functional dimensions, for example: Cardiac-PET-CT). The 3D Viewer offers all modern rendering modes: Multiplanar reconstruction (MPR), Surface Rendering, Volume Rendering and Maximum Intensity Projection (MIP). All these modes support 4D data and are able to produce image fusion between two different series (for example: PET-CT).

Osirix is at the same time a DICOM PACS workstation for medical imaging and an image processing software for medical research (radiology and nuclear imaging), functional imaging, 3D imaging, confocal microscopy and molecular imaging.

Osirix supports a complete plug-ins architecture that allows you to expand the capabilities of OsiriX for your personal needs! This plug-in architecture gives you access to the powerful Cocoa framework with an easy object-oriented and dynamic language: Objective-C.

A Wiki Manual is available.

Online music and its controversies are unavoidable, and with no end of hunger for access to tunes, the market has been an evolving battleground. With mavericks (in the non-Palin sense) like the aptly-named Grooveshark seeking to take a bite out of things, it’s refreshing to know that some services are using a lateral method — a “blue ocean” approach, you might say.

SoundCloud is one such service. Previously in invite-only beta, SoundCloud launched publicly in October. The service lets you “move music fast & easy. The platform takes the daily hassle out of receiving, sending & distributing music for artists, record labels & other music professionals.”

Anyone can sign up for a free SoundCloud account that includes five track uploads a month. They’re already distinguishing themselves by simplifying the process of sending demos to record labels, something which has historically been done by sub-optimal “attach an MP3″ email or form submission. I’ve done a lot of multimedia compilation, and all those extra steps to sort files gets tiring and dampens the joy of listening.

Beyond the usual...

Here’s where it gets really exciting: SoundCloud is exceptionally blissful to use. Not just pretty, but practical. Beyond the usual AJAX and Flash touches that reduce page reloads and imbue a sense of sheen, there are helpful features that are often found on desktop music apps but seldom on web ones.

For example, after a song’s uploaded, you can tap BPM (Beats Per Minute). Part of the reasoning behind this is because SoundCloud has started holding remix contests, where knowing the tempo is essential to syncing parts, also known as “stems”, with others. Even better, you get a true waveform with your beautifully embeddable widget — a pleasure to navigate, especially if you’ve ever been disappointed by all the pseudo-volume meters and fake waveforms out there (which is a Flash dev’s inside joke in some circles).

Even the upload process is a pleasure. While there’s no batch uploader yet — which would be highly time-saving for musicians with large catalogs who’ve upgraded to the somewhat confusingly-named “PRO Max” account @ €60/month — the uploader is as close to a practical flow as I’ve seen: you use a standard browser to select a file, a progress bar with countdown appears, and there are a few required fields.

Not just MP3s are uploadable: WAV, AIF, AAC, FLAC and OGG are supported. This is great news for professionals concerned about lossless fidelity. If desired, you can add genre details, and being forward-thinking, they’ve included Creative Commons as a licensing choice. The only unfriendliness I came across was getting a weird “(-280)” error after uploading that I wasn’t able to reproduce.

Feature request: as your music collection builds, it’d be great to mass-set permissions. And keywords should be clickable to find other stuff tagged similarly, as the similarly orange-and-purple Jamendo allows.

If you run a site and want to accept music, you can embed a SoundCloud DropBox in your sidebar, as Synthtopia has done. The first time I saw it, my first reaction was to drag an MP3 from my desktop to it — unfortunately that didn’t work, as it’s really just a button you click to get to the standard upload form. Nonetheless, I’ve noticed more of these popping up, suggesting they’re catching on.

What about the social aspects of SoundCloud?

You can add timed comments to a track, which is handy for calling out highlights like “OMG THIS BREAKDOWN ROX!” A few video-sharing sites like Viddler have a similar feature, and it’s not unlike adding markers or hit points in a full-fledged DAW.

You can choose whether your uploaded tracks are public or private. Interestingly, even if you’re on a free account, I discovered you can go above the five tracks/month limit by uploading to your own or other people’s DropBoxes, and I’ve asked SoundCloud about how this is intended to work. There’s a public gallery of Hot Music and Latest Tracks, and mandatory social networking features like adding friends are present. In this Rickroll Era, even MC Hammer is getting in on the fun:

And suitably, when they can’t build their own solutions, SoundCloud piggybacks on complementary companies, using Seesmic for video blog comments and Get Satisfaction for support. I’ve also noticed they have a running Flickr stream of photos tagged “soundcloud.” Observing what other companies SoundCloud is aligned with gives glimmers into their philosophy on creating community. I haven’t extensively tested their help yet, but have seen numerous positive experiences.

Kudos to SoundCloud for their excellent screencasts. They communicate well and compel you to try it out firsthand — with so many sites competing for your attention, a good video tutorial can really “sell” you what it’s all about in a couple minutes and drive your decision to get started.

3 things to look out for:

1. SoundCloud touts their API for plugging in custom apps to their tech. Well-documented, open APIs helped spread Flickr and Twitter’s popularity, so it’ll be intriguing to see what it does for this burgeoning audio service.

2. Copycats of their design by other sites. SoundCloud’s taken the usual “Web 2.0″ staples (starburst graphics, share-this buttons) and done an exemplary amount of going further and leading by unique example. But even if you can bite their style, you can’t steal their community.

3. Will SoundCloud’s freemium business model succeed in the long run? They currently don’t accept PayPal, but say it’s “coming soon.”

Give SoundCloud a go and share your experiences in the comments. Have a fave site that combines the best of substance + style? Let us know!

Hi,

I have started converting my library of FLAC audio files to ALAC used together with iTunes.

Is there an app out there that will check the integrity of the converted ALAC/FLAC files and compare it to the old FLAC file to verify that no artifacts were introduced when converting them?

Btw, I know FLAC to ALAC is lossless.

Many thanks in advance.
